If 9 is 1/3 of the problem, then 9 x 3
= 27 would be the answer
Answer:
3
Step-by-step explanation:
$1.75 (ice cream) + $0.35 (topping) * x (some toppings) = $2.80, so I can rewrite it like that: 1.75+0.35x=2.80
1) Move the constant to the right side and change its sign: 0.35x=2.8-1.75
2) Substract the numbers: 0.35x=1.05
3) Divide the both sides of the equation by 0.35
4) x=3
4 yards x 36inches = 144
144/15inches=9.6
So the maximum is 9 ribbons with a little material left over.
