Answer:
[tex]n = \frac{49}{2x}[/tex]
Step-by-step explanation:
1) Simplify [tex]\frac{4}{7}[/tex] xn to [tex]\frac{4xn}{7}[/tex]
[tex]\frac{4xn}{7}[/tex] = 14
2) Multiply both sides by 7.
4xn = 14 × 7
3) Simplify 14 × 7 to 98.
4xn=98
4) Divide both sides by 4.
[tex]xn = \frac{98}{4}[/tex]
5) Simplify [tex]\frac{98}{4}[/tex] to [tex]\frac{49}{2}[/tex]
[tex]xn = \frac{49 }{2}[/tex]
6) Divide both sides by x.
[tex]n = \frac{49}{2} / x[/tex]
7) Simplify [tex]\frac{49}{2} /x[/tex] into [tex]\frac{49}{2x}[/tex]

FINDDD VALUE OF Y!!!!
Answers
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

y = 10

Answers
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.

Answer:
Kindly check explanation
Step-by-step explanation:
Given the information above :
A) Cost equation for Newton Telephone company :
y = 8x
Where x = number of minutes used
y = total cost for x minutes
Cost equation for Tryus telephone company :
y = connection fee + (fee per minute * number of minutes)
y = 42 + (2x)
Where x = number of minutes used
y = total cost for x minutes

Answers
Answer:
10.5 = x
Step-by-step explanation:
7:x = 2:3
can be rewritten as
7/x = 2/3
because, a proportion is the same as a fraction, which is the same as division
so now use cross products to solve the equations
7/x = 2/3
7 * 3 = 2 * x
simplify

10.5 = x
7/2 = 3.5
3.5 x 3 = 10.5

12x35=420
Answer:
Distance = 420cm/s
Step-by-step explanation:
We have been given that Insect is crawling in a straight line at a speed of 12cm/s.
We have the following outcomes from the question.
Speed of insect = 12cm/sSo, We need to find the distance which can be reached out by insect in next 35 Seconds.
We are familiar with distance formula which is given by , Distance = Speed × Time
Distance = Speed × Time
Or, Distance = 12cm/s × 35
Or, Distance = 420 cm/s
Therefore, Insect is crawling in a straight line at a speed of 12cm/s, 420cm/s will the insect travel in 35 seconds.

We can rearrange it in a way that would make it easier to solve our problem:

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
Answers
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.
Step-by-step explanation:
Find the values of x, y, and z. The diagram is not to scale.
Answers
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°

The denominator represents the number of components into which the whole has been subdivided. It is positioned below the fractional bar in the lower section of the fraction.The numerator specifies how many fractional parts are depicted or selected. It is positioned above the fractional bar in the upper section of the fraction.We have to divide 3/8 by 2/3
So, 3/8 ÷ 2/3
