Add EF and DE together to equal 32
2x-10 + 4x = 32
Combine like terms;
6x-10 = 32
Add 10 to each side:
6x = 42
Divide both sides by 6:
x = 42/6
X = 7
EF = 2x-10 = 2(7)-10 = 14-10 = 4
DE = 4x = 4(7) = 28
Answer:
look at the picture i sent
65 lbs= 1040 oz
120 people x 6 oz = 720 oz
1040-720 = 320 oz or 20 lbs left
sum is an answer to an addition problem, so we have to add 43 and z. z+43=72.98
Subtract 43 on both sides.
z=29.98

hope it helps
So she cuts them so each one has 8 since there are two there will be 16 pieces
Out of those 16 she uses 12
So the fraction would be 12/16
But wait! We need to simplify it
Half it
6/8
Half it again
3/4
There ya go!
