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
It would be 2.31 i think.. If not i apologize.
Two possibilities:
28^2 + x^2 = 96^2
OR
28^2 + 96^2 = c^2
784 + x^2 = 9216
subtract 784 from both side
x^2 = 8432
Take the square root of both sides
x = 91.83 NOT an Integer
28^2 + 96^2 = c^2
784 + 8216 = c^2
10,000 = c^2
Take the square root of both sides
c = 100 HYPOTENUSE
A dozen eggs is 12 eggs.
Divide 1.12 by 12
1.12/12=0.93
Then multiply it by 3
.093*3=.28
3 eggs would cost you 28 cents.
