How do i solve this using elimination to get an ordered pair?

The ordered pair would be (-2, 1)

Step-by-step explanation:

To solve and get an ordered pair, we need to get a term to cancel. We can do this by multiplying the entire second equation by 2

4x + 3y = -5

-4x + 4y = 12

7y = 7

y = 1

Now that we have the value of y, we can use it to find x.

-2x + 2y = 6

-2x + 2(1) = 6

-2x + 2 = 6

-2x = 4

x = -2

117

Step-by-step explanation:

Okay, the problem is asking that we find the hypotenuse of this triangle (AKA, the lake.)

a²+b²=c²

A= 75

B= 90

C is always the hypotenuse.

75²+90²= c²

5,625+8,100= 13,725

√13,725= 117.15374513859981591194584103639

To the nearest whole number: 117

To the nearest tenth: 117.2

Hope this helps!
