Answer:
A) 160 minutes
Step-by-step explanation:
First we write an equation
0.05x + 24 = 32
Subtract 24 from both sides
0.05x=8
Divide by 0.05 on both sides
x=160
So that mean at 160 minutes the plans will cost the same!

Answer:
- 26 ounces of 55% solution
- 104 ounces of 80% solution
Step-by-step explanation:
Let x represent the quantity of 80% solution. Then 130-x is the amount of 55% solution. The total amount of salt in the mix is ...
0.80x +0.55(130 -x) = 0.75·130
0.25x = 0.20·130 . . . . . . . subtract 0.55(130)
x = 0.20/0.25(130) = 104
130-x = 26
She should use 26 ounces of 55% solution and 104 ounces of 80% solution.
It is a down shift of 3.
Also written as (x, y-3)
Answer:
Figure out what x is for both equations, then you can tell if the equations are the same
Step-by-step explanation:
1. 4x+1=9
x = 2
4 x 2= 8
2x+1=5
x = 2
2 x 2 = 4
4 does not = 9 so no.
75,000 divided by 150, is 500, meaning they allow 500 people per acre. 500 times 145 is 72,500, meaning the capacity for a park your size should be 72,500 people.
