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
Answer:
24
Step-by-step explanation:
the question translates to asking how many times does 7/8 fit in 21, so 21 divided by 7/8.
when we divide by a fraction, we can multiply by it's inverse, so 21 divided by 7/8, is 21 multiplied by 8/7. so:
21×8/7 = (21×8)/7 = (21/7)×8 = 3×8 = 24
