Answer:
correct answer is A
She chose C because she added the numerators and the denominators
Step-by-step explanation:
7/5x5/10=35/50 or 7/10
Answer:
x = 20
Step-by-step explanation:
the angles shown are supplementary
supplementary angles add up to 180°
hence, 5x - 7 + 3x + 27 = 180
==> combine like terms
8x + 20 = 180
==> subtract 20 from both sides
8x = 160
==> divide both sides by 8
x = 20
Answer:
I dont know for sure, but maybe try B
