#4(a)

row-seat: 3- 13, 4-15, 5-17, 6-19, 7-21

(b)

the equation works for row 1 but not for any of the rows after this

Ex: Row 2, S=7(2)+2, this would equal 14 but there isn't 14 seats in row #2

(c)

S=2(1)+7, there is 9 seats in row 1

2(2)+7=11,  there is 11 seats in row 2

2(3)+7= 13, there is 13 seats in row 3

(d)

2(15)+7=37

2*15=30, 30+7=37

(e)

91=2(r)+7

91-7=2(r)+7-7

84=2(r)

84/2=2(r)/2

42=r, the row with 91 seats is row 42

3x + 5y = 7<br> -3x - 2y = -1
Oksanka [162]

Answer:

(-1,2) y=2 x=-1

Step-by-step explanation:

This is a system of equations and in this you see there is 3x and negative three x. To solve this you need tp get rid of one of the variables. so we can add the two equations together to get 3y=6. This means that y=2 if we divide by 3 on both sides. Then we just plug 3 in for y and we get 3x+10=7. We subtract 10 on both sides to get 2x=-3 which means x=-1.

A factory uses 1/6 of a barrel of raisins in each batch of granola bars. Yesterday, the factory used 1/2 of a barrel of raisins.
balu736 [363]

1/6 = 1 batch, 2/6 = 2 batches and so on

if the factory used 1/2, the factory used 3/6 of a barrel, which equals to 3 batches.

<em>hope it helps :)</em>
