Answer:
Rather than just multiplying 5/4 with 8, she has to multiply it with 3 + 8. She could put parentheses around the 3 + 8, according to PEMDAS, this would mean that the parenthesis must be solved before multiplication. The correct answer would be:
4/5x - 8 = 3
4/5x = 3 + 8
x = (3 + 8)5/4
x = 11 x 5/4
x = 55/4 or 13.75
Answer:
w=3 h=4
Step-by-step explanation:
14=2w+2h w=(3/4)h
substitute
14=2(3/4)h+2h
distribute
14=1.5h+2h
simplify
14=3.5h
divide both sides by 3.5
4=h
plug into original equation
w=(3/4)4
w=3
Answer:
