Can someone please help me? I don't understand this. A system of equations is given below:

y = –2x + 1
6x + 2y = 22

Which of the following steps could be used to solve by substitution? (4 points)

Select one:

a. 6x + 2(–2x + 1) = 22

b. –2x + 1 = 6x + 2y

c. 6(–2x + 1) + 2y = 22

d. 6(y = –2x + 1)

Answers

Answer 1

Answer: Substitution is when you take the x (or y) value in the first equation and insert it into the second equation, and solve for both values.

y = –2x + 1
6x + 2y = 22

Now, given the y value (first equation), we can insert that into the SECOND equation.

6x + 2(-2x + 1) = 22

the only choice that demonstrates the above equation is A)

So, here's your answer ⇒ a. 6x + 2(–2x + 1) = 22

Good luck with your assignment!

Find the sum of 362+265. Explain why you did or did not regroup.

Answers

Answer:

627

Step-by-step explanation:

We have to find the sum of the given expression which is:

We start adding from right hand digits

we will first add right most digit of 362 and 265

which is 2+5=7

Now, the previous right most digit from both the numbers which is 6+6=12

Now, since, we are getting a two digit number we will consider right digit from the resultant which is 2 and 1 will be taken as carry to the next two digits that are to be added

Now, we will ad next two digits that are left which is 3+2=5 and 1 carry will be added

Hence,6

Final result is written as in sequence they were added which is 627

The answer would be 627. You would have to regroup because when you add 6+6 the number has two digits so you have to carry the one.
I hope this helps!
