Y = 3x

SAT
1 answer:
Anna71 [15]2 years ago
3 0

Answer:

-12

Explanation:

We are given information to solve for 2 variables x and y. To solve this I substituted 3x for y in the equation 5x - 4y = 21

So substituting gets us 5x - 4(3x) = 21

and we can solve the equation for x

5x - 12x = 21

-7x = 21

x = -3

Now that we have found x, we can find y simply by putting it in the equation y = 3x

y = 3(-3) = -9

Once we have both variables, we can find the answer to x + y

-3 + -9 = -3 - 9 = -12

So the answer to the question

x + y = -12

USPshnik [31]

Assuming $20,000 represents uncollected november sales. The total cash collected during january by lagrange corporation would be:$331.500.

<h3>Total cash collected</h3>

First step

Total Credit Sales in December= $50,000/40%

Total cash collected during January=$70,000+204,000+37,500+$20,000

The correct answer is A)

Explanation:

This is because the chances that the company will prevent additional expenses on the treatment of the ailment is 75% which is higher than that of the other drug whose effectiveness is at best 40% less than the expected results and 15% reduced than drug A.
