Answer:

30 liters of 50% acid solution!

Step-by-step explanation:

x-liters of 50% acid solution

We need a total of 60*0.6 liters of acid

    *36 liters of acid

0.5x+0.7(60-x)=36 (liters of acid)

Expand

0.5x+42-0.7x=36

0.2x=6

x=30

(To solve this informally you can think that you need equal amounts of both solutions since 0.6 is the average of 50% and 70% acid solutions)

2/3x - 1/2y = 3
nevsk [136]
2/3x - 1/2y = 3    |multiply both sides by 6

4x - 3y = 18

1/2x + y = 5    |multiply both sides by 2

x + 2y = 10

Answer: 4x - 3y and x + 2y = 10.

Three bags of chips and sodas cost $12.50. Four bags of chips and two sodas cost $10.00. What is the cost of each item? ASAP pls
Helen [10]

Step-by-step explanation:

3c + 3s = 12.50

4c + 2s = 10.00

3S = 12.50-3c

s = 4.17 - c

4c + 2 (4.17-c) = 10.00

2c + 8.34 = 10.00

2c = 1.66

chips = 0.83

soda = 3.34

The sides of a rectangle are 3t - 2 and 5t + 7. Write an expression for the perimeter of the rectangle.
natka813 [3]
How does this have anything to do with factoring?
Perimeter of the rectangle would just be 2(3t-2)+2(5t+7)
Simplify that to get 6t-4+10t+14, then 16t+10
