84 is 75% of what number?

Let x be the number required,

x * 75% = 84

x = (100*84) /75

x = 112.

Therefore 84 is the 75% of 112.

should be 112 :)

Step-by-step explanation:

84 = 75%

so 25% = 84÷3=28

28=25%

25% + 75% = 100% (the whole)

so 28+84=112.

You can use the inverse to work this out also :)

If 112 = 100%

56=50%

28=25%

Add the 50% to the 25% to get the 75%, which gives us 84 :)

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
