5/6 - 2/3 divide by 4/5

5/24

Step-by-step explanation:

Start with the first part of the probelm 5/6 - 2/3

You need to find a common denominator of 6 nad 3

which is 6

so change 2/3 to 4/6

now you can subtract the top values and simplify if needed

5/6-4/6

= 1/6

cant simplify so you move on

Now divide 1/6  by 4/5

to divide you are going to multiply by the reciprocal

so 1/6 x 5/4

5x1=5 and 6x4=24

= 5/24

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.
