You can turn them into decimals:
3 1/4 = 3.25 1/4 = .25
3.25 divided by .25 = 13

Bogdan [553]

Let x represent the number of liters of 50% acid Theresa puts into the mix. The the number of liters of 30% acid will be (420-x). The total amount of acid in the final solution will be ...
0.50x + 0.30(420-x) = 0.45(420)
0.20x + 126 = 189 . . . . . . . . . . . . . . . simplify
0.20x = 63 . . . . . . . . . . . . . . . . . . . . . subtract 126
x = 63/0.20 = 315 . . . . . . . . . . . . . . . liters of 50% solution
(420-x) = 420-315 = 105 . . . . . . . . . liters of 30% solution

Theresa should mix ...
105 liters of 30% solution

Solve for x. Your answer must be simplified. 17r > -17

Snowcat [4.5K]

Hello :D

Answer:

$\boxed{R>-1}$

The answer should have a negative sign.

Step-by-step explanation:

First, you do is divide by 17 from both sides of an equation.

$\frac{17r}{17}>\frac{-17}{17}$

Then, you simplify and solve to find the answer.

$-17\div17=-1$

$\boxed{R>-1}$ , which is our answer.

I hope this helps you!

Have a great day! :D

What is the solution of 2m=-6n-5 when n=1,2,3

Travka [436]

Answer:

Step-by-step explanation:

Simplifying

2m + -6n + 5n + 3m = 0

Reorder the terms:

2m + 3m + -6n + 5n = 0

Combine like terms: 2m + 3m = 5m

5m + -6n + 5n = 0

Combine like terms: -6n + 5n = -1n

5m + -1n = 0

Solving

5m + -1n = 0

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add 'n' to each side of the equation.

5m + -1n + n = 0 + n

Combine like terms: -1n + n = 0

5m + 0 = 0 + n

5m = 0 + n

Remove the zero:

5m = n

Divide each side by '5'.

m = 0.2n

Simplifying

m = 0.2n
