To find:
The equations for Nancy and Juan.
Solution:
Let x be the number of seconds.
Nancy is running 3 meters per second. So, the total distance covered by Nancy in the race is
[tex]y=3x[/tex]
Juan starts the same race 3 meters ahead of Nancy but he is going at 2 meters per second. So, the total distance covered by Juan in the race is
[tex]y=3+2x[/tex]
Therefore, the equations of Nancy and Juan are [tex]y=3x[/tex] and [tex]y=3+2x[/tex] respectively.

Dividing Fractions
The division of two fractions \frac{a}{b} and \frac{c}{d} is written as:
[tex]\displaystyle \frac{\frac{a}{b}}{ \frac{c}{d}}[/tex]
This division is usually easier done by multiplying the numerator by the reciprocal of the denominator:
[tex]\displaystyle \frac{\frac{a}{b}}{ \frac{c}{d}}=\frac{a}{b}\cdot \frac{c}{d}[/tex]
Jessie was dividing these two fractions:
[tex]\displaystyle \frac{\frac{1}{4}\ pounds}{ \frac{1}{8}\ quart}[/tex]
And got the incorrect result
[tex]\displaystyle \frac{1}{32}\ \text{ pound per quart}[/tex]
This mistake was probably the result of multiplying both fractions instead of dividing them.
The correct operation is:
[tex]\displaystyle \frac{\frac{1}{4}}{ \frac{1}{8}}=\frac{1}{4}\cdot \frac{8}{1}=\frac{8}{4}=2[/tex]
The correct result is 2 pounds per quart

Priya, and Jibran take 1 hour and 10 minutes working together to deliver all newspapers on their route. Priya, when working alone, can finish the delivery route 5 minutes faster than Jibran. How many minutes does it take each person to complete the route if they worked alone
Answer:
Priya takes 32 minutes and 30 seconds to complete the route and Jibran takes 37 minutes and 30 seconds to complete the route.
Step-by-step explanation:
We have that Priya (P) and Jibran (J) take 1 h + 10 min working together:
[tex] P + J = 60min + 10min = 70 min [/tex] (1)
Also, Priya can finish the delivery 5 minutes faster than Jibran:
[tex] P = J - 5 [/tex] (2)
By entering equation (2) into (1) we have:
[tex] (J - 5) + J = 70 min [/tex]
[tex] 2J = 75 min [/tex]
[tex] J = 37.5 min = 37 min + 30 s [/tex]
Hence, Jibran takes 37 minutes and 30 seconds to complete the route.
Now, by entering J into equation (2):
[tex] P = 37 min + 30 s - 5 min = 32 min + 30s [/tex]
Therefore, Priya takes 32 minutes and 30 seconds to complete the route.
I hope it helps you!
Answer:
Priya takes 32 minutes and 30 seconds to complete the route and Jibran takes 37 minutes and 30 seconds to complete the route.

FINDDD VALUE OF Y!!!!
Answer:
The sum of the internal ángles = 360°
(3y+40)° and (3x-70°) are suplementary angles = 180°
then:
(3x-70) + (3y+40) + 120 + x = 360 ⇒ first eq.
(3y+40) + (3x-70) = 180 ⇒ second eq
development:
from the first eq.
3x + x + 3y = 360 + 70 - 40 - 120
4x + 3y = 430 - 160
4x + 3y = 270 ⇒ third eq.
3y = 270 - 4x
y = (270 - 4x) / 3 ⇒ fourth eq.
from the secon eq.:
3y + 3x = 180 + 70 - 40
3y + 3x = 250 - 40
3y + 3x = 210 ⇒ fifth eq.
multiply by -1 the fifth eq and sum with the third eq.
-3y - 3x = -210 ⇒ (fifth eq. *-1)
3y + 4x = 270
⇒ 0 + x = 60
x = 60°
from the fourth eq.
y = (270-4x)/3
y = (270-(4*60)) / 3
y = (270 - 240) / 3
y = 30/3
y = 10°
Probe:
from the first eq.
(3x-70) + (3y+40) + 120 + x = 360
3*60 - 70 + 3*10 + 40 + 120 + 60 = 360
180 - 70 + 30 + 40 + 120 + 60 = 360
180 + 30 + 40 + 120 + 60 - 70 = 360
430 - 70 = 360
Answer:
y = 10

Find the values of x, y, and z. The diagram is not to scale.
Answer:
95 = x
85 = z
75 = y
Step-by-step explanation:
**remember** all triangles contain 180 degrees
this means that the triangle to the left should add up to 180 to we can set up this equation
180 = 60 + 25 + x
180 = 85 + x
95 = x
now **remember** a flat line is 180 degress so x + z is 180... we can set up this equation:
x + z = 180
plug in x = 95 from before
95 + z = 180
z = 85
**remember** again that a triangle in 180 degrees so for the right one we can set up this equation by pluggging in the z=85
180 = 20 + 85 + y
180 = 105 + y
75 = y
Answer:
first option
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , thus
x = 180° - (60 + 35)° = 180° - 95° = 85°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
z is an exterior angle of the triangle , thus
z = 60° + 35° = 95°
Using the sum of angles in a triangle, then
y = 180° - (95 + 20)° = 180° - 115° = 65°
Thus
x = 85°, y = 65°, z = 95°

Un apostador pierde en su primer juego el 30% de su dinero, en el segundo juego pierde el 50% de lo que perdió; finalmente en el tercer juego pierde el 40% de todo lo que ha perdido quedándole 37 soles para seguir apostando. Dar como respuesta el dinero que el apostador tenía al principio menos su 75%
Responder:
26,62
Explicación paso a paso:
Sea x el dinero original que tenía el jugador:
si un jugador pierde en su primer juego el 30% de su dinero, la cantidad perdida será;
[tex]= 30/100 \ of \ x\\= 0.3x[/tex]
Si en el segundo juego pierde el 50% de lo que perdió, entonces la cantidad perdida en el segundo juego será:
[tex]= 50/100 \ of \ 0.3x\\= 0.5 \times 0.3x\\= 0.15x[/tex]
Si en el tercer juego pierde el 40% de todo lo que ha perdido, la cantidad perdida en el tercer juego será:
[tex]=\frac{40}{100} \ of \ (0.3x+0.15x) \\= 0.4(0.45x)\\= 0.2025x[/tex]
Si la cantidad que le queda para seguir apostando es de 37 soles, entonces para calcular la cantidad original que tiene, sumaremos toda la cantidad perdida y la cantidad restante y equipararemos la cantidad original x como se muestra:
0,3x + 0,15x + 0,2025x + 37 = x
0,6525x + 37 = x
x-0,6525x = 37
0,3475x = 37
x = 37 / 0,3475
x = 106,48
La cantidad que tenía originalmente era de 106,48
75% de 106,48
= 75/100 * 106,48
= 0,75 * 106,48
= 79,86
Tomando la diferencia entre su monto original y su 75% será:
[tex]= 106.48-79.86\\= 26.62[/tex]

You are designing a hike that starts at the top of the canyon, above sea level. You plan to stop at three locations: •a scenic landmark, which is at sea level •famous boulder, which is below sea level •the bottom of the canyon, which is 600 feet below sea level
Answer:
Hello your question is incomplete attached below is the complete question and solution as well as the detailed solution
Step-by-step explanation:
The total change in elevation as represented in the number line is
600 - 600 = 0 ( sea level )
below sea level = 0 - 200 = -200 (where the famous boulder is located)
-200 -400 = - 600 feet ( bottom of canyon)
The variables y and x have a proportional relationship, and y = 24 when x = 16.
What is the value of x when y = 36?
x = 16
x = 24
x = 36
x = 54
Answer:
b) x = 24
Step-by-step explanation:
if y is 24 and x is 16, they make the fraction [tex]\frac{24}{16}[/tex]
this can be simplified to [tex]\frac{3}{2}[/tex] if you divide both sides of the fraction by 8.
36/3 is 12, and 12 * 2 = 24.
so, x = 24
Answer:
x=24 or B is the correct answer.

What is the equation in point-slope form of the line that passes through (-9, 12) with a slope of 5/6?
A. y-12=6/5(x+9)
B. y-12=5/6(x+9)
C. y-9=5/6(x-12)
D. y-12=6/5(x-9)
Answer:
The equation of the line is y - 12 = [tex]\frac{5}{6}[/tex] (x + 9) ⇒ B
Step-by-step explanation:
The slope-point form of the linear equation is
y - y1 = m(x - x1), where
m is the slope of the line(x1, y1) are the coordinates of a point lie on the line∵ The slope of a line is [tex]\frac{5}{6}[/tex]
∴ m = [tex]\frac{5}{6}[/tex]
∵ The line passes through point (-9, 12)
∴ x1 = -9 and y1 = 12
→ Substitute these values in the form of the equation above
∵ y - 12 = [tex]\frac{5}{6}[/tex] (x - -9)
→ Remember (-)(-) = (+)
∴ y - 12 = [tex]\frac{5}{6}[/tex] (x + 9)
∴ The equation of the line is y - 12 = [tex]\frac{5}{6}[/tex] (x + 9)

A triangle has all different side lengths and angle measures.
A triangle has all equal side lengths and angle measures.
A triangle has 2 equal side lengths and 2 equal angle measures.
A triangle has 2 equal side lengths and 2 equal angle measures.
Answer:
A
Step-by-step explanation:
A triangle has all different side lengths and angle measures have? 0 reflectional symmetries . Option A is correct.
Which triangle has 0 reflectional symmetries to determine.
The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
For a triangle that has 0 reflectional symmetries implies the triangle must be of irregular shape. Every measure must not be identical. If any measure in the triangle is not the same means every side and angle has a different measure. So it is impossible to find any axis of symmetry within the triangle
Thus, a triangle has all different side lengths and angle measures have? 0 reflectional symmetries. Option A is correct.
