Answer:337.5 miles
Step-by-step explanation:
Find the unit rate 135/6 = 22.5/1
He can drive 22.5 miles on 1 gallon of gas
Then multiply by 15
22.5x15= 337.5
x + y= 9 and x - y= 3
rearrange the second equation:
x - y= 3
x = 3 + y
x -3 = y
substitute y with "x-3" in the first equation and solve
x + y= 9
x + (x-3)= 9
2x -3 = 9
2x = 12
x = 6
you could also start with the first equation and substitute y in the second.
graphically speaking, it's the intersection point of to lines, at least the six-part of the point.
Area of circle= 153.93804
(38.485/153.93804)*360=90.00114592
so about 90 degrees or 10.99557429
Hope this helps and feel free to leave a rate, thanks and brainliest (it would really help me get to virtuoso I would appreciate it a lot) ;)
Answer:
Step-by-step explanation:
Answer:
Step 2.
Step-by-step explanation:
When you have a coefficient on a side of the equation that you need to get rid of, you must divide by the number. For example, in the problem:
3(x+8)² = 75
Here, you need to divide both sides by '3' instead of multiplying, which was done instead. Then you get:
(x+8)² = 25.
Therefore, his mistake was made at Step 2.
