Answer:
w=p/2-l
Step-by-step explanation:
you have to simplify the equation p=2(l+w).
1) Isolate the variables l and q
p/2=l+w
2) Subtract the length from the width.
p/2-l=w
3) The answer is b, or w=p/2-l
I'm assuming your allowed to use a calculator for this? That's what I would do.
To go about the fraction, take the whole number and times it by the denominator, then add in the numerator to create a new fraction(a whole one not mixed). Then simply divide the numerator by the denominator.
193 is the new numerator and the new whole fraction is this and dividing it out gives you,
For the third one, just input it into a calculator,
The answer is 8.
half of 16 is 8
Answer:
let x=distance 105 mph train traveled
(456-x)=distance 85 mph train traveled
Travel time = distance/speed (equal in both directions)
x/105=(456-x)/85
85x=105*456-105x
190x=105*456
x=105*456/190=252 miles
travel time=252/105=2.4 hrs
ans:
The two trains will meet in 2.4 hrs
