Answer:

Lawns ---Earnings

1 ----------------- 10

2 ----------------- 20

3 ----------------- 30

5 ----------------- 50

Step-by-step explanation:

Given

Earnings = $10 per lawn

Required

Complete the table

Let y be the earnings for x number of lawns

Since he earns $10 per x lawns, then the expression is:

y = 10x

To complete the table, we have the following:

When x = 1

y = 10 * 1 = 10

When x = 2

y = 10 * 2 = 20

When x = 3

y = 10 * 3 = 30

When x = 5

y = 10 * 5 = 50

So, the complete table is:

Lawns ---Earnings

1 ----------------- 10

2 ----------------- 20

3 ----------------- 30

5 ----------------- 50

What number is x if the equation is 2x-7=3
Elanso [62]

Hello there!

2x - 7 = 3

Solve for x

2x = 3 + 7

2x = 10

x = 10/2

x = 5

Therefore, the number of x in the equation is 5

Let me know if you have additional question!
