Answer:
The cost of parts was $65.
Step-by-step explanation:
Let the cost of parts = x
35 + 21(3) + 1.10x = 169.50
98 + 1.10x = 169.50
71.50 = 1.10x
71.50/1.10 = 65
Step-by-step explanation:
Perimeter=2length+2width
=2×20 + 2×18
40+36

Answer:
ok so first we add 10 plus 7 together since if you don't show up you fail
which is 17
so out of 100 students 17 failed both
now we subtract 71 from 80 to get 9
so we add that together with 17 so
17+9=26 so 26 students failed both
Hope This Helps!!!
0.5(5-7x)=8-(4x+6)To start distribute the 0.5 and the negative to get 2.5-3.5x=8-4x-6
minus the 6 from the to get 2.5-3.5x=2-4x
subtract the 2 from both sides (it doesn't matter what side you choose to leave the x on when you solve, you will still get the same answerI) to get 0.5-3.5x=-4x
add the 3.5 to both sides to get 0.5=-7.5x
divide by -7.5 to get x=-0.066666666
