The ratio of the number of boys to the number of girls in the class is 5: 7. if there are 600 students, how many girls are there?

There are 350 girls

Step-by-step explanation:

boys: girls: total

5            7     5+7

5           7        12

We can use proportions to solve this.  Put the number of girls over the total number.

girls            7 girls      x girls

= =

total            12total     600 total

Using cross products

7 * 600 = x*12

Divide each side by 12

7*600/12 = x

350 = x

There are 350 girls

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
