Hello!

Answer:

$\Large \boxed{\sf CD= 18}$

Step-by-step explanation:

→ We want to calculate CD.

We know that CD = DE.

→ So we have this equation:

$\sf 3x-6 = 2(x+1)$

→ Let's solve this equation to find the value of x to find CD:

◼ Simplify the right side:

$\sf 3x-6 = 2x+2$

◼ Add 6 to both sides:

$\sf 3x-6+6 = 2x+2+6$

◼ Simplify both sides:

$\sf 3x = 2x+8$

◼ Subtract 2x from both sides:

$\sf 3x-2x = 2x+8-2x$

◼ Simplify both sides:

$\sf x = 8$

→ Now, let's calculate CD, let's replace x by 8:

$\sf CD = 3x-6\n\n= 3 * 8 - 6\n\n= 24 - 6\n\n\boxed{\sf= 18}$

Check:

$\sf CD = DE\n\n3x-6 = 2(x+1)\n\n3 * 8 - 6 = 2(8+1)\n\n24 - 6 = 2 * 9\n\n18=18$

So the check is good.

Conclusion:

CD is equal to 18.

A basketball player has already scored 56 points in a game. The team record for points in a game is 72. Which equation would allow you to find out how many more points the player needs to tie the record?a. 72 + x = 56
b. 56 − 72 = x
c. 56 + x = 72
d. 56 + 72 = x

Answers

C. 56 + x =72 because the team player already scored 56 points you would need to add an unknown amount of points in this case x to find out how many points you need in order to reach 72 points and if you are curious how many points you need in order to get to 72 you need 16 points.

Answer:

C. 56 + x =72

What number is midway between 2/3 and 1?

Answers

5/6 is about midway through 2/3 and 1. It helps if you lay everything out in a number line like below:

0______________1/4______________ 2/4______________3/4___________1

0____________________1/3___________________2/3________________ 1

0________1/6________ 2/6________3/4_________4/6________5/6_______1

Additionally, 2/3 = .66 so the distance from 2/3 to 1 is approximately .34. If you divide that by 2 to see what the middle is you get .17, which you then add to .66.

.66 + .17 = .83

.83 = 5/6

Answer:

5/6

First of all, she wants to INCREASE her steps per day. A, B, and C all have the same number of steps or fewer steps. I can further prove that the answer is D because if she stars walking 10 extra steps per day, 10 times 100 = 1000 and 5000 + 1000=6000. Please correct me if I am wrong because everybody makes mistakes sometimes. Also, thanks so much for giving me brainiliest!
