The subtraction property of inequality can be used to proof that x = 7 from x + 8 = 15
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Given that x + 8 = 15
Hence:
x + 8 - 8 = 15 - 8 (subtraction property of inequality)
x = 7
The subtraction property of inequality can be used to proof that x = 7 from x + 8 = 15

Answer:
Y=2.50x+3
Step-by-step explanation:
Because the $3 fee is not changing but the 2.50 is changing every pound that they get.
So the ratios are 5:5 and 3:5 so the fractions are 5/10 (1/2) for 7th grade and 5/8 for 8th grade
Just multiply across which is
8*5 = 40
21*16 = 336
40/336 = 5/42
This is correct answer
I hope this answer helped you!!! Thank you!!!
