Step-by-step explanation:
x = -4y + 6
Now,
Substituting the value of x on 2x + 9y = 16, we get -.
2(-4y + 6) + 9y = 16
-8y + 12 + 9y = 16
y = 16 - 12
<h3>y = 4</h3>
Now,
Substituting the value of y on 2x + 9y = 16, we get -
2x + 9(4) = 16
2x = 16 - 36
2x = -20
<h3>x = -10</h3>
Hence,
The value of x is -10 and y is 4.
For this question, you're required to work backwards....
Average monthly salary= $4560
Yearly Salary= $4560 x 12
= $54,720
Hope this helps :))
Answer:
55 = 5x
Step-by-step explanation:
Sadie had 55 stickers. Each day she gave away 5 stickers to her friends.
Write an equation to model this situation in the form y = mx + b, but do not
include any spaces in your answers. (for example y=6x+1)
Equation to model this situation in the form y = mx + b,
y = Total number of stickers she had
x = Number of days that she gave away sticker
b = Fixed value = 0
Hence:
55 = 5x + b
b = Fixed value = 0
Therefore, the situation is represented as:
55 = 5x
Answer: 110
Step-by-step explanation:
Given;
Total cost C = $151
Enrollment fee E = $30
Charge per 10 test t = $11
n is the number of packet of test taken.
The questions can be represented by the equation below;
30 + 11n = 151
Substracting 30 from both sides.
11n = 151-30 = 121
n = 121/11
n = 11
Since the number of packet of test is 11 and each packet contains 10 tests. The number of test N is given by;
N = 10 n = 10 ×11 = 110
N = 110
Answer:
286 in³
Step-by-step explanation:
7×5 = 35
35×2 = 70in
9×5 = 45
45×2 = 90in
9×7 = 63
63×2 = 126in
70+90+126
=286in³
