A. To answer this item, we let x be the number of aluminum cans and y be the number of plastic bottles. With this representation, the total money that is gained from the sales is 0.10x and 0.05y. The equation then becomes,

                   0.10x + 0.05y = 500

B. If the value of y is 6000 then,

                   0.10x + 0.05(6000) = 500

The value of x is 2000.

Solve for the unknown.

Based on the balance sheet of Company MSK, we can find the unknown amount of Net Income (loss) to be $18,843.

<h3>What is the Net Income (loss)?</h3>

The Assets as at 2021 should be equal to the sum of liabilities and equity.

The Equity is:

= Issued stocks + Net income - Dividends

The missing figure is therefore:

35,564 = 15,721 + 1,400 + Net Income - 400

Net Income = 35,564 + 400 - 15,721 - 1,400

= $18,843

A pharmacist has a 12% solution and a 20% solution of boric acid. How much of each should she use to make 80 grams of a 15% solu
nlexa [21]

Step-by-step explanation:

If x = the amount of 12% and y = the amount of 20%, then x + y = 80

Since we need 80 grams of 15%, 80(.15) = 12.

We are given that .12x + .20y = 12.

We can solve the first equation for x or y. Let's do x.

x = 80 - y

.12(80 - y) + .20y = 12

9.6 - .12y + .20y = 12

.08y = 2.4

y = 30

x = 80 - 30 = 50

Eight less than a number is six more than twice the same number.<br> I need the number.
mariarad [96]
The answer is -14


Explanation:

x - 8 = 2x + 6

We move all term to the left

x - 8 - ( 2x + 6 ) = 0

We get rid of parentheses

x - 2x - 6 - 8 = 0

We add all the numbers together, and all the variables

-1x - 14 = 0

We move all terms containing x to the left, all other term to the right

-x = 14
x = 14/-1
x = -14
