Question

Please help me with this one

Answer 1

1. 43

2. 360

3. 105

Explanation:

1.

We don't know what the 4 hearts are, so we can write an algebraic expression and solve for it

`4x=172`

Divide by 4

`x=43`

2. We don't know what the arrows are, so we can write an algebraic expression and solve for it.

`x-85=275`

Add 85 on both sides

`x=360`

3. We don't know what the box is, so we can write an algebraic expression and solve for it.

x + 47 = 152

Subtract 47 on both sides

`x=105`

Answer 2

43, 360, 105

Explanation:

For the first one, simply divide 172 by 4 and you will have your answer

172/4 = 43

For the second one add 85 and 275 for the answer

275 + 85 = 360

For the last one subtract 47 from 152 for the answer

152 - 47 = 105
