Angle 1 is vertical to Angle 2. Angle 1 =94, Angle 2 = 2(x-13), Find the value of x.
rodikova [14]

Answer:

x= 56

Step-by-step explanation:

86+94= 180 which if supplementary angles have to equal 180°

I don't know if you can tell but what's in red means distribute

then I added 26 on both sides with like terms

on the left side 86+26=112 and right side is left with 2x

then divide both sides by 2 to leave x by itself

112/2= 56 and 2x/2=x

so 56=x

Help me solve please! The math club has 57 members who are in sixth or seventh grades. There are twice as many sixth graders as
saul85 [17]
We know there is 57 members are in the math club and there is twice as many sixth grades than the seventh. To find out how many sixth graders are in the club, we do:

x = seventh graders
2x = sixth graders

2x + x = 3x

57=3x
57 ÷ 3 = 3x ÷3
19 = x

So there is 19 seventh graders and 19×2= 38 sixth graders
