How long is the line between the two cities on the map? I see that you wrote 15/8 inches. That can't be right. If it is then the correct answer is not one of the choices. If it's really 15/8 inches then their average speed would be 48 miles per hour.
We know that the original price is 160 and has increased to 248. To calculate the increase, divide. But first lets find the difference 248-160 =88
The percentage increase is 55%.
<span>2x+3y=7
x-y=1
</span>2x+3y=7
x=1+y
2*(1+y)+3y=7
x=1+y
2+2y+3y=7
x=1+y
5y=5 |(:5)
x=1+y
y=1
x=2
CHECK:
2x+3y=7
x-y=1
2*2 + 3*1 = 7
x-y = 1
2-1 = 1
Okay, so basically all you need to do is combine like terms!
in this case, 4y and -3y are like terms... and -1 and 2 are like terms
so, 4y - 3y is 1y or y
and -1 + 2 is 1
so your simplified answer is y + 1
I hope this helps!!
It’s the 2nd your welcome
