210 kilometers. You can do this by taking the distance divided by the time. In this case it would be 840/4 which would be 210 kilometers an hour.

Which property is used to simplify the expression 5(3x +18) to 15x+90
natka813 [3]

Answer:

Distributive

Step-by-step explanation:

You distribute the 5 into 3x+18, multiplying it by each part of the equation (each part is separated by one of these signs: +, -, x, or /) to get 15x (from 5 x 3x) plus 60 (from 5 x 18).

There are 100 balloons in total the ratio between the yellow and blue balloons is 8 to 12 how many are yellow
Virty [35]

If you have 8 yellow balloons for every 12 blue balloons, then if you have 20 balloons in total, 8 out of 20 of those balloons will be yellow. Then you can set up this ratio.

Then, you can use either cross multiplication or multiply the numerator and denominator by the same number to help solve for x. Personally, I prefer cross multiplication.

Finally, solve for x and if you had 100 balloons, you will have 40 yellow balloons.
