Answer:

x = 2

Table:

0,0

3,9

-2,-6

4,12

Step-by-step explanation:

distribute

3(2x+1)=15

6x+3 = 15

subtract 3 from both sides

6x + 3 = 15

6x + 3 - 3 = 15 - 3

simplify

6x= 12

divide both sides by 6

answer= x=2

"If an integer n is odd, then n+1 must be even."

gladu [14]

Answer:

True.

Step-by-step explanation:

Let me clear it to you by an example:

if you take n=1,3,5,7,...... which are odd numbers

then adding 1 with them will give you n+1=2,4,6,8.... which are even numbers.

That's how, if an integer n is odd, then n+1 must be even.

Similarly, if you let n as even numbers, then n+1 will be odd.

Double check your work:

7+16+11+12+10+16= 72

kupik [55]

Answer:

19.17 feet of lace will be leftover.

Step-by-step explanation:

Given:

Kaitlyn is making a quilt she purchased a 46 feet long piece of lace to sew around the edges of the quilt she needs 322 inches of lace for the quilt.

Now, to find the feet of lace will be leftover.

Total feet of lace = 46.

Kaitlyn needs lace for the quilt = 322 inches.

So, by using conversion factor we change inches into feet:

12 inches = 1 foot.

322 inches = $\frac{322}{12} =26.83\ feet.$

Feet of lace she need for the quilt = 26.83.

Now, to get the feet of leftover lace:

Total feet of lace - feet of lace she need for the quilt

$=46-26.83$

$=19.17\ feet.$

Therefore, 19.17 feet of lace will be leftover.
