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!!

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.

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)

The newest phone by Samsung finally came out and costs $499. You were one of the first people in line to buy it so you got a 15% discount and there was a 8.5% tax. What was the total cost of the phone?

Answers
