Can Someone Please Explain How They Got 12??

Answers

Answer 1

Answer:

They got 12 by multiplying 3 × 4

Step-by-step explanation:

They used distributive property to multiply the 3 by each number in the parentheses

3 × x/3 = 1x = x

3 × 4 = 12

x + 12 = 6 × 3

They mutliplied 6 × 3 to get 18

x + 12 = 18

They then subtracted both sides by 12 to isolate the variable

x + 12 - 12 = 18 - 12

x = 6

Answer 2

Answer:

hope this helps! lmk if you still dont understand it!

:)

Step-by-step explanation:

you do 3*4 which gives you 12 and 3*x/3, but you should keep it as x

6*3 is 18

x+12=18 (solve for x)

-12=-12

x=6

check the answer:

3*(6/3+4)=6*3

3(2+4)=6*3

6+12=6*3

18=18

Three consecutive odd numbers sum to 1,245. What are the three numbers? ​

Answers

Answer:

413, 415, 417

Step-by-step explanation:

Answer:

414, 415, 416

Step-by-step explanation:

Consecutive numbers means they come one after another, like 1,2,3,4,5... So they all follow the formula x, x+1, x+2, x+3...x+n.

Since there are 3, we can say that x+(x+1)+(x+2)=1,245.

Simplify that to 3x+3=1,245, and then subtract 3 from both sides.

We get 3x=1,242. Divide that by 3, and you get x=414.

Add 1 and 2 to 414, and you get 414, 415, and 416.

You can add them up to check.

Why is the relationship between surface area and volume central to many cellular processes? Leander was a youth of Abydos, a town of the Asian side of the strait [narrow ocean channel] which separates Asia and Europe. On the opposite shore, in the town of Sestos, lived the maiden Hero, a priestess of Venus. Leander loved her, and used to swim the strait nightly to enjoy the company of his mistress, guided by a torch which she reared upon the tower for the purpose. But one night a tempest arose and the sea was rough; his strength failed, and he was drowned. The waves bore his body to the European shore, where Hero became aware of his death, and in her despair cast herself down from the tower into the sea and perished. Source: Bulfinch, Thomas.
