11d + 17b = 95
d + b = 7
Answer:
{d,b}={4,3}
Step-by-step explanation:
[1] 11d + 17b = 95
[2] d + b = 7
Graphic Representation of the Equations :
17b + 11d = 95 b + d = 7
Solve by Substitution :
// Solve equation [2] for the variable b
[2] b = -d + 7
// Plug this in for variable b in equation [1]
[1] 11d + 17•(-d +7) = 95
[1] -6d = -24
// Solve equation [1] for the variable d
[1] 6d = 24
[1] d = 4
// By now we know this much :
d = 4
b = -d+7
// Use the d value to solve for b
b = -(4)+7 = 3
Solution :
{d,b} = {4,3}
Answer:
B = 3
d = 4
Step-by-step explanation:
You can use elimination method. Multiply (d + b = 7) by -11.
11d + 17b = 95
-11d - 11b = -77
add together. D’s will cancel
6b = 18
divide by 6
b = 3
plug in 3 for b in the equation of your choice
d + (3) = 7
subtract 3
d = 4

Answer:
im sure its [tex]\frac{1}{6}[/tex]
Step-by-step explanation:
hope it helps and Merry Christmas xx
Answer:
[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
Proabability = favorable outcomes / total outcomes
A die has a total of 6 possible outcomes: 1 to 6
You want to roll a 3, so the number of favourable outcomes is 1.
[tex]\therefore[/tex] P(3) = [tex]\frac{1}{6}[/tex]

Answer:
7 miles per hour.
Step-by-step explanation:
Right now, the relationship in the problem represents 3[tex]\frac{1}{2}[/tex] miles in hours. To find out what the unit rate is (number of miles per mile), we need to multiply both sides of the equation show BeLoW:
3[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{2}[/tex]
7 miles = 1 hour
Therefore, Doug's average speed in miles per hour is 7 (7 miles per hour).

The Science Club went on a two-day field trip. The first day the members paid $70 for transportation plus $19 per ticket to the planetarium. The second day they paid $100 for transportation plus $16 per ticket to the geology museum. Write an expression to represent the total cost in dollars for two days for the n members of the club.
Answer:
$170 + $35n
Step-by-step explanation:
Given that:
First day:
Transport fare = $70
Fee per ticket = $19
2nd day:
Transport fare = $100
Fee per ticket = $16
Total cost in dollars for the two days for n members
Number of members = n
First day:
70 + 19n
Second day :
100 + 16n
Totak cost :
(70 + 19n) + (100 + 16n)
70 + 100 + 19n + 16n
170 + 35n
$170 + $35n
0=(2y−1)(8−y) Let y=u, y=d. What is the value of u×d
Answer:
The value of uxd=4
Step-by-step explanation:
since y=u, y=d, y=y
y=1/2 and 8
2y-1=0
2y=1
y=1/2
8-y=0
8=y
1/2*8=4
Answer:
4
Step-by-step explanation:
0=(2y−1)(8−y)
Using the zero product property
2y-1 =0 8-y =0
2y =1 8=y
y =1/2 y= 8
Let y=u, y=d
u = 1/2 d = 8
We want the value of u*d
u*d = 1/2 *8 = 4

(triangles) if FGH= QRS, find the measure of
Answer:
Option (4)
Step-by-step explanation:
From the picture attached,
ΔFGH ≅ ΔQRS
Therefore, ∠F ≅ ∠Q
m∠F = m∠Q
(2x + 10)° = (3x + 1)°
3x - 2x = 10 - 1
x = 9
m∠Q = (3x + 1)°
= 27 + 1
= 28°
Option (4) will be the correct option.

Answer:
D.) This system has no solutions (The one you chose is correct)
Step-by-step explanation:
y = 8x + 9
-8x + y = -1
-8x + y = -1
y = 8x - 1
These two lines will also never meet as the slope are both 8, but the y-intercept is different, to check, look at the graph below.
Answer:
You're right, the system has no solutions
Step-by-step explanation:
y=8x+9
-8x+y=-1
-8x+y=-1
y=-1+8x
8x+9=1+8x
9≠1
The system has no solutions

Evaluate y = 2x + 1 when x= -1
Answer:
y = -1
Step-by-step explanation:
We Know:
y = 2x + 1, and x= -1.
Substitute:
y = 2(-1) + 1
Multiply:
2 * -1 = -2
y = -2 + 1
Add:
-2 + 1 = -1
So,
y = -1.
