There are 632 fans at a concert if there are 3 seats in each row how many rows will be needed to seat all the fans

211

Step-by-step explanation:

Number of fans : 632

Number of seats per row : 3 seats

number of rows needed

= number of fans ÷ number of seats per row

= 632 ÷ 3

= 210.66666

because partial rows do not make sense, we round this number up to to the next largest whole number = 211 rows

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

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

)=(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.
