This to numbers are equal
Answer:
A. P/2 - L = W
B. 9/5C + 32 = F
Step-by-step explanation:
A. P = 2L + 2W
P = 2(L+W)
P/2 = L + W
(P/2)-L = W
B. C = 5/9(F - 32)
9/5C = F - 32
9/5C + 32 = F
Answer:
My answer is that x = 4.4
Step-by-step explanation:
The answer to the equation is 6, so the false one is the last one. All the other ones are true.
Answer $100 each
Step-by-step explanation:
2500/25
The equation is
time= distance/rate
and the train is going 300 miles
the car is going 200 miles
the train goes 20 miles faster than the car
fitting the numbers into the equation
200/r=300/(r+20)
cross multiply
200/r = 300/(r+20)
200(r+20) = 300r
distributive property
4000+200r=300r
subtract 200r from both sides to add like terms
4000=100r
divide 100 from each side to get r by itself
40 = rate of car
60 = rate of train
