Answer:
54
Step-by-step explanation:
since n = 3
= -2n ( 5n+n-8-3n)
= -2 (3) ( 5+(3)-8-3(3) )
= -6 (5+3-8-9)
= -6 (5-5-9)
= -6 (-9)
= 54.
It seems to me this just wants you to add the 3 equations.
2m + 2n +5p
Use a variable to represent the number of hours the technician will work, plus the $50.
50+25x
This would be the expression used to find the amount of money the technician needs.
Answer:
$20.16
Step-by-step explanation:
First we need to find 12% of his current hourly rate, 12% is our decimal multiplier here so we use 0.12. In order to get 12% we need to multiply our decimal by $18 which is:
$18 × 0.12 = $2.16
Now let's add this 12% on top of his current hourly rate.
$18 + $2.16 = $20.16
And that's the final answer.
