Answer:

1: X= 8, 2: 2/5 or 0.4

Step-by-step explanation:

1: 2(2x + 1) + x = x + 2x + 18

5x + 2 = 3x + 18

2x = 16

x = 8

2: 2x + x + 2x = 10 + x

5x = 10 + x

4x = 10

x = 4/10

x = 2/5

x = 0.4

you have $18 to buy peppers. peppers cost $1.50 each. write and solve an inequality that represents the number of peppers you ca

Nezavi [6.7K]

At most 12 peppers can be bought with $18

Step-by-step explanation:

Given

Total amount for peppers = $18

Cost per pepper = $1.50

Let p be the number of peppers that can be bought from $18 at $1.50 per pepper

So,

$1.50p\leq 18$

Dividing both sides by 1.50

$\frac{1.50p}{1.50}\leq \frac{18}{1.50}\\p\leq 12$

Hence,

At most 12 peppers can be bought with $18
