Answer:
100*24 = 2400
Step-by-step explanation:
when doing simple multiplication problems like this, you have an equal number of zeros before and after the equals sign. so you can break it down to 1*24 which is just 24, and then adjust it to 2400 since it was 100 and not just 1.
245
let 'c' = total coins
2/7 = 70/c
2c = 490
c = 245
the whole exam will be 100%, and let's say that's "x" questions, but we also know that 9 is 60% of that so
the x s are the independent variable so any direct change to them is changing the independent. like the second one has -5 on the x
50
