Answer:
The numbers are -14,-13 and -12
Step-by-step explanation:
<u><em>The correct question is </em></u>
Find three consecutive integers such that the sum of the first, twice the second and three times the third is -76. What is the number?
Let
x ----> the first consecutive integer
x+1 ---> the second consecutive integer
x+2 ---> the third consecutive integer
we have that

solve for x
apply distributive property

Combine like terms

subtract 8 both sides


Divide by 6 both sides

so


therefore
The numbers are -14,-13 and -12
This equation can be set up letting x be the hourly rate:40x+1.5x(52-40)=638 [40 times the rate, plus 1.5 times the rate for the hours over 40 equals the pay]40x+78x-60x=63858x=638x=11 hourly rate is $11/hr
Simplifying is basically 1 + 1, so the answer is 2, or 8/4 whichever you prefer.
It can also be 4/2, or 2/1...
