before school began mrs. weeks bought a total of 86 balls us the information below to help you write a numerical expression

STALIN [3.7K]

For this case we have that the total of the balls is 86. We know there are 8 footballs then:

Basketball: Two more than twice the number of footballs are basketballs, that is:

$2 + 2 (8) = 2 + 16 = 18$

There are 18 Basketballs.

Baseballs: Four less than 5 times the number of footballs are baseballs, that is:

$5 (8) -4 = 40-4 = 36$

There are 36 Baseballs.

Softballs: Six more than half of baseballs are softballs. That is to say:

$6+ \frac {36} {2} = 6 + 18 = 24$

There are 24 Softballs

If we add we must get 86.

$8 + 18 + 36 + 24 = 86$

ANswer:

There are 8 Footballs

There are 18 Basketballs.

There are 36 Baseballs.

There are 24 Softballs
