Alexis and martin the school set chairs in rows for an assembly. they put the same number of chairs in each row. using 92 chairs available, alexis made 4 rows with 2 chairs left over while martin made 5 rows with no chairs left over. write and solve an equation that can be used to find the number of chairs in each row.

4c + 5c = 92 - 2

9c = 90

c = 10

22 chairs were not used in the assembly.

x/7.50 = 15

x= 7.50 / 15 divide

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
