Answer:
-1 1/2
same as -1.5 but since you are dealing with fractions you should put it in fraction form unless told otherwise.
Answer:
Step-by-step explanation:
Let M = total amount of money earned
M = 12x+8y
To make more than $190, the equation is:
190<12x+8y
Since Trevor is going to scoop ice cream for 20 hours, the equation is:
190<12x+8(20), which simplifies to 190<12x+160.
Isolate x to find the amount of hours that Trevor needs to tutor.
190-160<12x
30<12x
30/12<x
2.5<x
Trevor must tutor for more than 2.5 hours to make more than $190.
Let that be x

Answer:
13
Step-by-step explanation:
Explanation:
Use the absolute value definition to rewrite the absolute value equation as two separate equations.
k-10=3
k-10=-3
Solve the equation for k
k=13
k-10=-3
k=13
k=7
The equation has 2 solutions, meaning k1=7,k2=13. Which gives you the answer of: 13 (K1=7,k2=13)
