Hello,
Assume v the speed of the eastbound train,
v-14 the speed of the westbound train
v*4+(v-14)*4=800
==>8v=800+56
==>v=107 (mi/h)
Speed of the westbound train: 107-14=93 (mi/h)
Hello.
Each side I believe would be 3 in.
Hope it helps!
The equation is

×

First, you need to solve the bases/exponents

is 5×5×5=125
Then you solve the second base/exponent but know that with negative exponents, you divide 1 by the number rather than multiplying

= 1÷5÷5=.04
So now the equation is 125×.04=5
Answer: 5
Answer:
None answer applicable, answer would be 2.05882353 incorrect question or no answer given with A.B.C.D
Step-by-step explanation:
4 * 105 = 420

420 / 204 = 2.05882353
Answer:
n = 20
Step-by-step explanation:
n/2 - 9 = 1
Add 9 to each side
n/2 -9+9 = 1+9
n/2 = 10
Multiply by 2 on each side
n/2*2 = 10*2
n = 20
