Solve the system of equations (show ALL work!). What is the value of x? y = x - 10
5x + y = 32
A. 8
B. 7
C. -2
D. -3
I

B) 7

Step-by-step explanation:

y = x -10   (I)

5x + y = 32 (II)

Substitute y = x - 10 in equation (II)

5x + (x - 10) = 32

5x + x - 10 = 32

    6x - 10  = 32

Add 10 to both sides

6x - 10 + 10 = 32+10

            6x    = 42

Divide both sides by 6

           x = 42/6

x = 7

Plugin x = 7 in equation (I)

y = 7 - 10

y = -3

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
