Three rectangular prisms have combined volume of 518 cubic feet prism a has one third the volume of prism b and prisms b and c have equal volume what is the volume of each prism

Translating the given problem into equation form:

Let A = volume of prism A

B = volume of prism B

C = volume of prism C

Eqn 1: A + B+ C = 518

Eqn 2: A = (1/3)B

Eqn 3: B = C

There are 3 equations and 3 unknowns, the system of linear can be solved. Using a calculator (preferably Casio 991-ES), yields:

A = 74 cu.ft

B = 222 cu.ft

C = 222 cu.ft

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.
