Answer:

x = 2

Step-by-step explanation:

4(2x - 1) = 3x + 6

Simplify

8x - 4 = 3x + 6

Subtract 3x from both sides

8x - 3x - 4 = 3x - 3x + 6

5x - 4 = 6

Add 4 to both sides

5x - 4 + 4 = 6 + 4

5x = 10

Divide both sides by 5

5x/5 = 10/5

x = 2

At many bakeries, there are deals that if you buy twelve donuts, you get a thirteenth one at a discount. Sometimes "13" items is

Mariana [72]

Table

Number of donuts Price

1 $1.05

2 $ 2.1

3 $3.15

4 $4.2

5 $5.25

6 $6.3

10 $10.5

slope = (10.5 - 1.05) / 10 - 1

= 9.45 / 9

= 1.05

Equation

y - 10.5 = 1.05 (x - 10)

y = 1.05x - 10.5 + 10.5

y = 1.05x

For 40 donuts

y = 1.05(40)

y = $42
