Answer 1

Answer:

Graph 3

Step-by-step explanation:

Given : Jamal earns $7 an hour Helping his neighbors.

             He wants to earn more than $105 altogether.

             He has already earned $63.

To Find:  Which graph shows the remaining number of hours Jamall could work to earn more than $105?

Solution:

Let x be the number of  the remaining number of hours Jamal could work to earn more than $105.

He earns in 1 hour = $7

He earns ion x hours = $7x

He already has money = $63

He wants to earn more than $105 altogether

So, equation becomes : $63+7x\geq 105$

$7x\geq 105-63$

$7x\geq 42$

$x\geq \frac{42}{7}$

$x\geq 6$

Thus the remaining number of hours Jamal could work to earn more than $105 must be 6 or more than 6 hours .

Since 6 is included . So, Graph 3 is correct.

Hence Graph 3 shows the remaining number of hours Jamal could work to earn more than $105 must be 6 or more than 6 hours.

Answer 2

Your inequality is 63 + 7h is equal or greater than 105. Subtract 63 to both sides to get 7h is greater than or equal to 42. 42/7 = 6, so the answer is 6 or greater. The answer is the third one. Hope this helped, and have a great day!
