-7 cuz -39.9 divided by 5.7 is -7
Answer:
$14
Step-by-step explanation:
After Shanice spent half of her allowance and earned $7, she is left with $14.
This means the remaining of her weekly allowance is $7, This can be derived by subtracting $7 from 15 - $14 - $7 = $7
This means that it is $7 that remains after spending half of her weekly allowance
her weekly allowance = $7 x 2 = $14
<span>Is this part of the problem?
The table is
x=2.5 y=6.25; x=9.4 y=88.36; x=15.6 y=243.36
In solving for x and y of an experiment, first is to get the slope and y-intercept of the line using the first and second points:
y=mx + b
6.25 = m*(2.5) + b
88.36 = m*(9.4) + b
Solving for the two unknowns using systems of linear equations (substitution or elimination method):
m= 11.9; b=-23.5
y=11.9x - 23.5
y=11.9*4-23.5
y=24.1
Therefore when x=4, the approximate value of y is 24.1
