I will mark as brainliest pls answer ASAP

let's devide the left equation by -1/2 to get it into a form that starts with y=...

y=-x-10

the right equation is

y=2x+2

since y=y the following must also be true (for the point where the two lines intersect):

-x-10=2x+2

add 1x on each side

-10=3x+2

subtract 2 on each side

-12=3x

devide by 3

-4=x

that's the x-information of the point. to get the y-information we plug it into one of the two function, any is fine actually, because the point we are looking for is on both of them after all.

I plug x = -4 into the second equation and get

y = 2*(-4) +2

y = -6

the two lines intersect at (-4,-6)

the answer is 31.27mph

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
