Answer:
-9
Step-by-step explanation:
Replace x with -7 in the expression:
x^2 + 5 / x + 1
-7^2 + 5 / -7 + 1
49 + 5 / -6
54/-6
simplify the fraction
9/-1 = -9
Translate the statements into equations. We can use 'x' for dimes and 'y' for quarters.
"<span>A boy has 11 coins in dimes and quarters"
"</span><span>Their value is $1.70"
</span>
<span>
To solve this, we can first solve for one of the variables in the first equation, and then plug that into the second equation:
Subtract 'x' to both sides:
Now plug this value of 'y' into the second equation:
</span>
So this equation could be used to solve the problem.

Thanks for making it more clear
Answer:
x = -17
Step-by-step explanation:
-17 + 5 = -12
-12 ÷ 4 = -3
50+75= 125$
125 divided by 65 = 1.92
1.92 rounds up to 2, so it would take approximately 2 hours.
If you need to find an exact number then we need to find a number greater than 125 that both 50 and 65 can fit into.
125+ 50 + 50 + 50 + 50= 325
325 divided by 65= 5
So it would take 4 hours of work with Abe to cost 325 and 5 hours of work with the other service.
