"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
Answer:
twelve decreased by twice a number > 12 - 2x
8 times the sum of number and 4 > 8 (x + 4)
12 - 2x = 8 (x + 4) then 12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)

Answer: 1:2
Step-by-step explanation: you have to subtract 80 from 120 to get 40. Then you would have the ratio 40:80. Then when you simplify it would be 1:2.
The visual work:
120-80=40
40:80=1:2
i know u didnt need the explanation and all that but just wanted to show you how i got it- lol
Answer:
Answer down below!
Step-by-step explanation:
If there were 80 blue marbles, but the amount of red marbles isn't stated. First, you need to figure out how many there are. 80 + Number = 120
Number = 40
The ratio is 80:40
Cutting that in half would be 40:20
We're getting closer
20:10
This is starting to get pretty obvious what our answer could be!
If we kept cutting we would get 2:1
Your answer is 2:1!!

−2(5r+ 3) + 9r?
A) −19r – 3
B) −10r – 6
C) −10r + 3
D) −r– 6
Answers
if you distribute the -2 to the 5r and 3 you get -10r and -6.
-10r + 9r = -r (then just add on the negative 6)
-r-6

Answer:
10 + (2 x 3) {2} divided by 4 x (1/2) {3} = 2.375 (2 3/8)
Step-by-step explanation:
2 x 3 is 6 and 6 to the power of 2 is 36, and PEMDAS makes it where you divided 36 by four instead of 46 (10 + 36) divided by 4. 36 divided by 4 = 9. 10 + 9 = 19. Then 1/2 to the third power is 1/8. 19 times 1/8 = 2.375 (2 3/8)

Tatiana is buying b number of books and m number of magazines at the book fair. The books cost $4 each and the magazines cost $2 each. Tatiana's total purchase can be shown with this expression: 4b + 2m. Which expression is equivalent to 4b + 2m?
Answers
Answer:
2(2b + m)
Step-by-step explanation:
We can simplify the expression given in the question using factoring:
4b + 2m
(2 x 2)b + (2 x 1)m
2(2b + m)
The equivalent expression is 2(2b + m).
What is meant by an expression?It is a sentence with a minimum of two numbers or variables and at least one math operation.
Given that b is the number of books and m is the number of magazines.
The cost of a book = $4
The cost of a magazine = $2
The given expression for Tatianan's total purchase is 4b + 2m.
The given expression can be simplified as
4b+2m = 2(2b+m)
Hence, 2(2b+m) is the equivalent expression of 4b+2m.
