Solve by elimination -3x+2y=10 -2x-y=-5

Nataly [62]

First you need to get two similar terms to eliminate, I'll do y:
-3x + 2y = 10
-4x - 2y= -10
And then you minus
x = 20
Now you can substitute x in to one of the equations to find y:
-60 + 2y = 10
+ 60
2y = 70
÷ 2
y = 35
So your values are y = 35 and x = 20. Hope this helps!

Can y’all help find the surface area please and thank you

solong [7]

To find the area of a complex shape:

⇒ must cut the whole shape into a simpler shape

square with side lengths of 4 in
2 triangles with a base of 4 in. and a height of 8 in.
2 triangles with a base of 4 in. and a height of 10 in.

Let's calculate:

Area of 2 triangles with a base of 4 in. and a height of 8 in.

$Area = \frac{1}{2}*4*8 + \frac{1}{2}*4*8=16+16=32\\$

2 triangles with a base of 4 in. and a height of 10 in.

$Area = \frac{1}{2}*4*10 + \frac{1}{2}*4*10=20+20=40$

square with side lengths of 4 in

$Area = 4 * 4=16$

Total Area: 32 + 40 + 16 = 88 in²

Answer: 88 in²

Hope that helps!
