Answer: y = 11/8 +7x/8
process: add 7x to both sides of the equation 8y=11+7x
Divide each term in 8y=11+7x by 8 and simplify
Answer:
100 minutes
Step-by-step explanation:
To solve this, we can make a proportion.
The bike travels 5 miles in 20 minutes, and 25 miles in x minutes
5/20=25/x
Cross multiply
5*x=20*25
5x=500
Divide both sides by 5. This will cancel out the 5, and leave x by itself.
5x/5=500/5
x=100
There are 60 minutes in 1 hour. If we subtract 60 from 100,
100-60=40
So, this is also equivalent to 1 hour and 40 minutes.
It takes 100 minutes, or 1 hour and 40 minutes, to travel 25 miles.
Third quartile=20
median=17
difference=20-17=3
Percent is pars out of 100
40%=40/100=4/10=0.4
'of' means multiply
0.4 times something=56
divide both sides by 0.4
something=140
th enumber is 140
Hi there
To solve this question
0.03x+0.05 (6000-x)=220
Solve for x to know How much money was invested at 3%
First multiply the values
0.03x+0.05×6000-0.05x=220
0.03x+300-0.05x=220
Second calculate the difference and rearranging the values
0.03x-0.05x=220-300
-0.02x=-80
Divide both sides by-0.02 and divide the values
X=-0.02/-80
x=4000 invested at 3% this is the answer of your question
While the amount invested at 5% is
6000-4000=2000
Good luck!
