Answer:

(2, 8)

Step-by-step explanation:

There are a couple of different ways to do this, but I am going to use substitution since we already have one of those equations solved for y. If y=3x+2, then we can sub 3x+2 in for y in the other equation:

-3x + 2(3x + 2) = 10 and

-3x + 6x + 4 = 10 and

3x + 4 = 10 and

3x = 6 so

x = 2. Now that we know x = 2, we can sub a 2 in for x in either equation to solve for y:

y = 3x + 2 gives us, with the substitution, y = 3(2) + 2 so y = 8. The solution set is (2, 8)

You find this by finding the number of yards in 15 feet (15÷3) and that number of yards in 24 feet (24÷3) and multiplying them together. 5X8=40sq yards.

Kira owes Mark $5, and Mark owes Kira $7. Which of the following statements means the same thing?

kvasek [131]

Answer:

Mark owes Kira $2.

Step-by-step explanation:

The correct answer is “Mark owes Kira $2” because first Kira owes $5 to the Mark and then Mark gives $7 to Kira. Here it can be seen that Mark is giving $2 extra and $5 is the amount which he is refunding. So the net amount $2 that the Mark gives to Kira. Therefore, the statement “Mark owes Kira $2” is justified and correct.
