What is the solution to the system of linear equations? Show your work using either substitution or elimination.

Problem:
3x-2y=7
y=x+2

please tell me how you got the answer.

Answers

Answer:

3x - 2y = 7

Where y = x + 2

3x - 2(x + 2) = 7

3x - 2x - 4 = 7

x = 11

Step-by-step explanation:

If you are solving for X and y = x+2 then you write the equation out like this.

3x - 2(x +2) = 7 …. You substitute the x + 2 for y and then solve for x.

2x - 2 times x + 2 times - 2 = 7. That becomes 3x - 2x - 4 = 7. You then subtract 2x from 3x to give you X. Then you add 4 on one side to zero it out and add 4 to the other side. 7 + 4 = 11. This gives you the answer X = 11.

A bakery sells chocolate, cinnamon, maple, honey, and jelly donuts. It currently has
48 total donuts in stock. If Xiwen picks one donut from the bakery at random, she
has a 1/4 chance of picking a chocolate donut. How many chocolate donuts does
the bakery have in stock?

Answers

Since the bakery has only 48 donuts in stock and Xiwen has a 1/4 chance of picking a chocolate donut, there are a dozen (12) chocolate donuts in stock.

1/4 = 0.25

Answers

Answer:

50L is larger than 500 ML because 1L=1000ml and. 1ML= 1 ML.

Step-by-step explanation:

Answer: 50 L

Step-by-step explanation:

In order to compare both, let's first transform 500 mL into L. We know that 1 L is 1000 mL. So 500 mL = 0.5 L. We should now look at both numbers. The answer would be 50 L, since 50 is superior to 0.5

Assume y=5x and dx/dt = 2 find dy/dt

Answers

The answer is “$10$”

Answer: 10

Step-by-step explanation: since dx/dt = 2, you have to create an equation. dx/dt = dy/dt * dx/dy is your equation. now we substitute. 2 = dy/dt *dx/dy. find the derivative of 5x in terms of y (dx/dy), which is 1/5. so now your equation is 2 = dy/dt * 1/5. solve for dy/dt and your answer is 10.
