IXL math problem

……………..

FI = 48

Step-by-step explanation:

We know that FI and IH are equal. so we can build an equation to solve this tricky and messy question which tries to scare you by giving additional information.

z + 22 = 4z -56

z - 4z = -56 - 22

-3z = -78

z = -78 / -3

z = 26

so we know FI = z + 22

                         = 26 + 22

                        = 48

FI = 48

Step-by-step explanation:

We know that FI and IH are equal. Sk we ca. build an equation to solve this question .

z + 22= 4z - 56

z- 4z = -56-22

-3z = -78

z= -78/-3

z= 26

So we know,

FI = z+ 22

= 26+22

=48

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
