Step-by-step explanation:

-9(2)-(-6)(2)+3(-20)

(−9)(2)−(−6)(2)+(3)(−20)

=−18−(−6)(2)+(3)(−20)

=−18−(−12)+(3)(−20)

=−6+(3)(−20)

=−6+−60

=−66

The ratio of boys to girl in a school is 5:7 if there are 600 students, how many girls are there

larisa86 [58]

Answer:

350 girls

Step-by-step explanation:

So,

The secret to solving problems with ratios is to find the value of one unit.

5:7 = 12 units total

To find one unit, divide the total number of students by the total number of units.

600/12 = a

Simplify

50/1 = a

50 = a

The value of each unit is 50.

Now, multiply the units by the numbers in the ratio.

50(5) = b

250 = boys

50(7) = x

350 = x

There are 350 girls.
