Rasek [7]

Answer:

Student B

Step-by-step explanation:

Student B

Their wages increase at intervals of $6 each hour.

6*1 = $6

6*2 = $12

6*3 = $18

6*4 = $24

6*5 = $30

6*6 = $36

6*7 = $42

6*8 = $48

This shows a proportional relationship between the wages earned and the number of hours worked. 

Hope this helps!

John wrote that 5+5=10.
Anvisha [2.4K]

By the additive property of equality, the equations John wrote are equivalent.

<h3>Additive property of equality: Determining equivalent equations</h3>

From the question, we are to determine if the equations John wrote are equivalent.

From the given information,

John wrote that

5 + 5 = 10

Then,

He added n to both sides of the equation to get

5 + 5 + n = 10 + n

From the Additive property of equality, we have that

"<em>If we add or subtract the same number to both sides of an equation, the sides remain equal</em>."

Since, John added the same number, n, to both sides of the equation, the equations John wrote are equivalent.
