Can someone help me with this problem 3(x+1)=11 I need it step by step

Nataly [62]

Answer:

x = 2.66666667

Step-by-step explanation:

3(x + 1) = 11

We multiply both x and 1 by 3 and get

3x + 3 = 11

Now we subtract 3 from both sides

3x + 3 - 3 = 11 - 3

3x = 8

Now divide both sides by 3

3x/3 = 8/3

x = 2.66666667

Write an equation that relates the number of peppers, n, and the<br><br> cost, C.

SCORPION-xisa [38]

Complete Question:

The local Farm Market sells peppers at five for $2.25. Write an equation that relates the number of peppers, n, and the cost, C.

Answer:

$C = 0.45n$

Step-by-step explanation:

Given

$5\ peppers = \$2.25$

Required

Determine the relationship between C and n

$5\ peppers = \$2.25$

Divide both sides by 5, to get the cost of 1 pepper

$\frac{5\ peppers}{5} = \frac{\$2.25}{5}$

$1\ pepper = \frac{\$2.25}{5}$

$1\ pepper = \$0.45$

Multiply both sides by n to get the cost of n pepper

$n*1\ pepper = \$0.45*n$

$n\ pepper = \$0.45n$

So, we have:

$C = 0.45n$
