Answer:
2
Step-by-step explanation:
6y+1= -y+15
6y+y= 15-1
7y=14
y = 14/7
y=2
if y=2 this equation is correct
Answer:
The total cost = $90
Step-by-step explanation:
As, $75 is the cost of the meal
And tip is 20%
So 20% of $75 = 15
So, the tip = $15
So, total = Cost of meal + tip
= $75 + $15 = $90
You'll be solving:
-5t^2 + 20t + 15 = 3t + 3
5t^2 - 17t - 12 = 0
(t - 4)(5t + 3) = 0
t = 4 or t = -3/5, but let's assume t ≥ 0
Step-by-step explanation:
Y=55
Explanation:
If you’re looking to see how 11 and y would match -9 and -45 you would find the unit rate of -9 and -45.
-9/-9=1
-45/-9=5
So if the y is going up by 5’s it would be 55.
