The boy walks at a constant speed V=3 m/s where V is his velocity
1 minutes has 60 seconds
Thus we conclude during 1 minute he travels :
60 seconds × 3 meters/second = 180 meters
OK, so for this equation, your goal is to get the d, and ONLY the d, on one side of the equation. So, to start out, you need to multiply the entire equation, meaning both sides, by 8 because we are trying to get rid of those pesky fractions.
8(1/8(3d-2)=1/4(d+5))
The equation then turns into this because the 8 and 4 cancelled out with the 8.
1(3d-2)=2(d+5)
Now, we need to distribute the left over numbers into the parenthesis.
3d-2=2d+10
And finally, we need to get the d's on one side, and the numbers on the other, so we subtract 2d from both sides and add the 2 to both sides. They then cancel out to make
d=12
Hope it helps! :)
if you add 4 to it then you would get 8
Answer:
6/1
Step-by-step explanation:
He read 90 pages in 3 hours so it's 30/1 pages/hour
Then he reads 180 pages in 5 hours so it's 36/1 pages /hours
the rate of difference is 30/1 ÷ 36/1 is 6 pages per hour
Tot ratio=11
330/11=30
So Ed pay 7x30=210
Fay pays 4x30=120
For Ed to give Fay money so they r equal, he would need to give $45 so that they both are at 165.
