Answer:

$3x^2-3y-8x$

Step-by-step explanation:

We have been given an expression $7y+2x-10y+3x^2-10x$ .

To simplify our given expression, we will combine like terms as:

$3x^2-10y+7y-10x+2x$

$3x^2-3y-8x$

Therefore, simplified form of our given expression would be $3x^2-3y-8x$ .

In a toy store, the ratio of the number of dolls to the number of teddy bears is . If the store has 240 dolls, how many teddy

forsale [732]

Answer:

So, the way a ratio works is "for every 1 of this, we have 4 of this" for example. (the ratio I just described would be 1:4.)

I believe I've seen this question before. If the ratio of dolls to teddy bears is 9:3 then for every 9 dolls you have 3 teddy bears.

So, since we have 240 dolls and a 9:3 ratio to teddy bears, all we have to do is take how many dolls we have (240) and divide it by 3 to see how many teddy bears we have.

So:

240 ÷ 3 = 80

If your ratio is 9:3, then 80 is your answer.

Hope this helps and have a nice day!
