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
Answer:
3/5 y +9/10 z
Step-by-step explanation:
4/5 y + 7/10 z - 1/5 y + 1/5 z
4/5 y - 1/5 y + 7/10 z + 1/5 z
We need to get a common denominator for the z term of 10
4/5 y - 1/5 y + 7/10 z + 1/5 *2/2 z
4/5 y - 1/5 y + 7/10 z + 2/10 z
3/5 y +9/10 z
