Answer:
60°
Step-by-step explanation:
The sum of angles in a triangle is 180°.
∠R + 88° + 32° = 180°
∠R = 60° . . . . . . subtract 120° from both sides of the equation
Answer:
D
Step-by-step explanation:

Share: Subtracting a number is the same as adding its opposite. So, subtracting a positive number is like adding a negative; you move to the left on the number line. Subtracting a negative number is like adding a positive; you move to the right on the number line.
Step-by-step explanation:
2x - 3y = -24
x+ 6y = 18
you solve the first one by the x:
2x = -24 + 3y
x = (-24+3y)/2
then you substitute what you found in the other equation and you solve by y
(-24+3y)/2 + 6y = 18 multiply everything by 2
-24 + 3y + 12y = 36
3y + 12y = 36 + 24
15y = 60
y = 60/15
y = 4
Good job! You found your y! :D
Now let's substitute the y in the first equation with 4:
2x - 3(4) = -24
2x - 12 = -24
2x = -24 + 12
2x = -12
x = -12/2
x= -6
Done!! ;) <span />
6w-y=2z
6w=2z+y
w=(2z+y):6
w=(z:3)+(y:6)
