Hope this helps.
Answer:
Step-by-step explanation:
x->5
y->2
x*5+y*2=60
if x=10——> y=5 ——> 50+10=60
if x=8——> y=10——> 40+20=60
if x=6——> y=15 ——> 30+30=60
if x=4——> y=20 ——> 20+40=60
if x=2——> y=25 ——> 10+50=60
So 3 is 3 and then .3 is 3/10 so fraction is 3 3/10
Answer:
y=6
Step-by-step explanation:
y=kx
3=9k

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
