B If It’s Wrong I’m Sorry
4 x 8 = 32
X essentially means “groups of”. So we have 4 groups of 8.
8+8+8+8
We can then add those
16+16
=32
1: Bettina's 60, and Melvina's 20.
2: 4.5 gallons
Answer:
x=10
Step-by-step explanation:
these are similar triangles
8 12
------ = -----------
x+4 2x+1
using cross products
8* (2x+1) = 12(x+4)
distribute
16x + 8 = 12x+48
subtract 12x from each side
16x-12x +8 = 12x-12x+48
4x+8 = 48
subtract 8 from each side
4x+8-8 = 48-8
4x = 40
divide by 4
4x/4 = 40/x
x =10
