The ratio of boys to girls in year 8 is 5: 6
if there are 72 girls in year 8, what is the total number of students is the year level?

132

Step-by-step explanation:

We can use proportions to solve this.  Set up as follows, with boy stuff on top and girl stuff on bottom.  We are looking for the number of boys when the number of girls is 72:

Cross multiply to get 6x = 360

and x = 60.

When there are 72 girls, there are 60 boys and

72 + 60 = 132 students total.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
