there are 90 pupils at primary school 48 of the are girls 1/3 of the girls and 2/3 of the boys play football complete the frequenxy tree

the answer to the expression is 83

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3

=

−37

−3

x=

37

3

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu

12 dolars one is cheaper becasue 3 pairs is 6 means is sock is 2 while the 12 is cheaper
