That's a vertical line, no slope, so no y=something.
Answer: x = -9
Answer:
28 miles in 7 minutes, 240 miles in an hour
Step-by-step explanation:
We can first simplify the rate to miles per minute. Since the plane goes 12 miles in 3 minutes, we can divide it by 3 to find how much it travels in one minute. 12 divided by 3 is 4 and 3 divided by 3 is 1
The plane travels 4 miles a minute
To find how much it travels in 7 minutes, multiply by 7
4x7 is 28
28 miles in 7 minutes
To find an hour, multiply by 60
4x60= 240
240 miles in an hour
(3/4*4)+(3/4*-x)= (3)+(-3/4x) = -3/4x+ 3
X= 3
Cancel 3 out by subtracting it by itself, then subtract 3 from 18 to get 15. Now that you have 5x= 15, just divide 15 by 5x to get x= 3
First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
83÷31
Applying the fractions formula for division,
=8×13×3
=89
=89
