Answer:
373248 cm³ of wax
Step-by-step explanation:
If the crayon is 90 millimeters long, how many cubic centimeters of wax is used to make a box of 8 crayons?
1 crayon = 90mm
8 crayons = x
Cross Multiply
x = 8 × 90mm
x = 720mm
Converting to cubic mm
= (720mm)³ = 373248000mm³
Converting to cubic centimeter
1 mm³ = 0.001 cm³
373248000 mm³ = x
Cross Multiply
373248000 × 0.001 cm³
= 373248 cm³ of wax

Y+3x=2----equation1
y-2x=-3-----equation 2
e1-e2
(y+3x)-(y-2x)=2-(-3)
y+3x-y+2x=5
5x=5
x=1
sub x=1 into equation 1
y+3(1)=2
y=-1
