Question

Translate the word phrase into a math expression. Sheila buys some boxes of pens, with 20 pens in each box. A. 20 + p B. 20 ÷ p C. 20 – p D. 20p

Answer 1

For each box she buys, she gets 20 pens. Therefore, it's a multiplication problem, so the answer is 20p.

Answer 2

thanks

Answer 3

this one is a big question

Answer 4

Which is an everyday situation for the math expression with the context provided?


; sharing something equally

A.
Each player in the league was given 100 tickets to sell. If there are p players in the league, the total number of tickets to sell is

B.
The coach received 100 tokens for the amusement park rides. If there are p players on the team, each player will receive tokens.

C.
After the league had supplied each player with a uniform there were 100 uniforms left over. If there are p players in the league is the total number of uniforms the league had.

D.
One hundred more players signed up for soccer than the league had planned for. They had p uniforms in stock. The number of uniforms they need to buy to make up the difference is .

Answer 5

Which expression describes the total accumulation of snow that fell at a rate of 3 inches each hour for h hours?

A.
3 + h

B.
3h

C.
3 – h

D.
h – 3

Answer 6

I don't really understand it.

Answer 7

For the first question, you can look at each problem in terms of its basic math concept.

A involves giving 100 of something to each person. It can be rewritten as x = 100p

B involves sharing 100 of something among several people. You can write this as x = 100/p

C involves reducing something from an unknown number to 100, so that's x - p = 100

D involves increasing something from a starting amount by 100, making it p - x = 100

"Sharing" is usually done via division, so I'd say the answer is B. The coach has to share the tokens among all the players.

Answer 8

For the second question, you can think of it like this:

Snow is falling at 3 inches per hour. After zero hours, you have no snow. After one hour, you have three inches of snow. After two hours, you have six inches of snow.

The only equation that gives you 3 inches of snow for every hour that passes is 3h. The others start out at the wrong number (some have 3 inches, some have negative 3 inches (!)) and have the wrong rate.

Answer 9

Oh! I see. Thank you!

Answer 10

Ok

I got a 100% on my test

Answer 11

Thanks so much!

Answer 12

Translate the phrase into a math expression.

twelve more than the quotient of six divided by three

A.
(6 ÷ 3) + 12

B.
6 ÷ (3 + 12)

C.
(3 ÷ 6) + 12

D.
3 ÷ (6 + 12)

Answer 13

When writing out an expression, consider the order of operations:

Parenthesis/exponentials ---> multiplication/division ---> addition/subtraction

In this case, you can break the statement down into two parts:

"twelve more than" ---> addition
"quotient of six divided by three" ---> division

The problem wants you to indicate which operation happens first. Since division comes before addition, you'll want to enclose six divided by three in parentheses.

Remember: These are the same thing-\[4\div2 + 3 = 5\]\[(4\div2) + 3 = 5\]The parentheses have no effect, since the order of operations already put division before addition.

On the other hand, this does have an effect:\[(4\div2) + 3 = 5\]\[4\div(2 + 3) = 0.8\]The order of operations changes due to the parentheses.
