Answer:
20x-21y+14
Step-by-step explanation:
1/5(100x-105y+70)
20x-21y+14
The volume is 675 because when you multiply 20x15 you get 300 and when you multiply 25x15 you get 375. When you add 375+300 you get 675 as your volume.
112 is 80% of 140.
80% can be written as 0.80 or 0.8.
how i got 140 is by finding the x value of this equation: 0.8x=112
to find the x, i divided 0.8 from both sides,
0.8 divided by 0.8 cancel out.
112 divided by 0.8 is 140.
therefore, 112 is 80% of 140
8 / 10 = 1/5 = 0.2
