Girls :Boys = 9:10

Total girls= 225

9=225

10=10/9×225

=250

NB: It will 250 because 9 is going to cancel 225

Answer:

250 boys

Step-by-step explanation:

We know that the ratio is 9:10 from girls to boys

Take 225 and divide it by 9

225 ÷ 9 = 25

So we know that 25 is a factor of 225

We can the number of boys and multiply it by 25 to get 250

If we put it in the ratio form:

225:250 = 9/10

Check work:

25 x 9 = 225

25 x 10 = 250

Find the slope of the line that goes through (0, 2) and (4, −2).

zmey [24]

M = (y2 - y1) / (x2 - x1)

m = (-2 - 2) / (4 - 0)

m = -4 / 4

m = -1

The slope of the line that goes through (0, 2) and (4, -2) is -1.
