White shapes and black shapes are used in a game. some of the shapes are circles. All the other shapes are squares. The ratio of the number of white shapes to the number if black shapes is 3:7. The ratio of the white circles to the number of white squares is 4:5z The ratio of the number of black circles to the number of black squares is 2:5. Work out what fraction of all the shapes are circles.

step-by-step explanation:

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.
