use cross products
(3r+6) *2 = 9*(2r-4)
6r+12 = 18r-36 distribute
12 = 12 r -36 subtract 6r from each side
48 = 12r add 36 to each side
4=r divide by 12
FALSE, there are 80 cups in 5 gallons and 88 cups in 22 quarts
Answer:
(6)
Step-by-step explanation:
Since it is an isosceles trapezoid the length of the two legs (i.e. AB = 5y-10 and CD = 2y+8) are equal. In other words,
5y - 10 = 2 y + 8
Subtract 2y from each side:
5y - 2y - 10 = 8
Now add 10 to each side
5y - 2y - 10 + 10 = 8 + 10 =>
3y + 0 = 18 =>
3y = 18 =>
y = 6
Answer:
The GCF of 27 and 72 is 9
Step-by-step explanation:
prime factorization of 27 is 3*3*3
prime factorization of 72 is 2*2*2 by 3*3
3*3 is in both, and so we need to multiply that to get our GCF. 3*# is 9, so the GCF of 27 and 72 is 9
