Mathematics

Is there supposed to be a attached file? Or are you confused about the topic in general. I can help if need be. I’ll start off with saying that a system of equation is two equations that either have infinite, no, or one solution. This solution makes x true for both equations. x will be the same value for each equation.

I need help!!! Brainliest for anyone who answers correctly on both!!!
timama [110]

Answer:

The first answer: 390m The second answer: x = 7; m<1 = 17; m<2 = 73

Step-by-step explanation:

First problem:

It's asking for the distance he walks by walking around a rectangular box which is the perimeter.

Two of the sides will have length 115m and two will have length 80m. So this perimeter is 115 + 115 + 80 + 80 = 390m.

Second problem:

Complementary angles add to 90 degrees. So m<1 and m<2 added together will equal 90

-4x +45 + 7x + 24 = 90

3x + 69 = 90

3x = 21

x= 7.

Plug back x into both m<1 and m<2 to find the measure of the angles.

m<1 = -4(7) + 45 = 45-28 = 17

m<2 = 7(7) + 24 = 49 + 24 = 73
