20% of a number is 1/5th of it so 50 × 5 is 250
A=binomial
B=trinomial
C=polynomial
D=binomial
E=trinomial
F=binomial
B = 0.5A + 30
C = 1.5A + 20
If B = C, that means we can set the two equations equal to each other.
0.5A + 30 = 1.5A + 20
A = 10... Plug that into one of the equations to find B or C (they are the same)..
B = 0.5 * 10 + 30 = 35
35 + 35 + 10 = 80 total.
Answer:
She has 4 pieces of pipe
Step-by-step explanation:
You have to just simply see how many 2 3/8 are in 9 1/2:
(9+1/2)/(2+3/8)=(19/2)/(19/8)=(8×19)/(2×19)=4
