Answer:

-2

Step-by-step explanation:

-7 + 5 = -2

If you have negatives and then add, the negative number will decrease.

if the question was -7 - 5, the answer would be -12. This is because when you subtract a number from a negative, the negative number becomes bigger.

n200080 [17]

Answer:

It is possibly: 19h+28 and if she worked 6 hours after she got the raise she would earn $142.

Step-by-step explanation:

I’m not quite sure what you are asking but here my best answer:

$16 per hour plus an extra $3 from the raise. 16+3= 19. And $5+$23 in bonus earnings for $28. So the new equation for her earnings is; 19h+28. If she works 6 hours; 19 (6) +28. 19 times 6 is 114. 114+28=142.
