Answer:x<-3
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
3(x+2) = 2(x+5)
Distribute
3x+6 = 2x+10
Subtract 2x from each side
3x-2x+6 = 2x-2x+10
x +6 = 10
Subtract 6 from each side
x+6-6 = 10-6
x = 4
Answer:
114
Step-by-step explanation:
Supplementary means that all the angles in your givens add up to 180 degrees.
Givens
<A + <B = 180
<A = 2x + 6
<B = x + 3
Solution
<A + <B = 180 Substitute for <A and <B
2x + 6 + x + 3 = 180 Combine like terms on the left.
3x + 9 = 180 Subtract 9 from both sides
3x = 180 - 9
3x = 171 Divide by 3
x = 171/3
x = 57
That's not your answer.
<A = 2x + 6
<A = 2*57
<A = 114
