Answer: 2 + 4d

Step-by-step explanation: In this problem, we're asked to simplify 2 + 3d + d. Notice that the 3rd term in this problem, <em>d</em>, has no coefficient. In this situation, we can give it a coefficient of 1.

Now, when simplifying this problem, it's important to understand that we can only combine like terms. Like terms are terms that have the same variables so we have 3d + 1d which is 4d. Since 2 has no like terms to combine with, it stays the same so we have 2 + 4d.

So our answer is 2 + 4d and we must stop here because these are not like terms since 2 does not have a variable.

Lucy earns $15.75 per hour. Last week she worked 25 hours. What is her gross pay:
Bumek [7]

Lucy's gross pay per week is $393.75.

Lance's tax payment amount is $10983.

Lance's net pay is $41,317.

Lance's every paycheck of two will be around $2179 per month.

<h3>How find the pay?</h3>

1) Lucy earns $15.75 per hour.

Last week she worked 25 hours.

Solution:

Lucy's gross pay per week is $15.75 * 25 hours.

Lucy's gross pay per week = 15.75 * 25  =  $393.75

2) Lance has a yearly salary of $52,300

He pays 21% as taxes.

Solution:

a) Lance tax pay amount = 21/100*52,300 = $10983

b) Lance's net pay =  $52,300 - $10983 =  $41,317

c) Per month salary = $52,300/12 =  $4358

Each paycheck will be 4358/2 = $2179

Gracie is buying new jackets for her dance squad. She will pay $26.50 for each jacket
Mariana [72]

Answer:

y=26.50x + 15.99

Step-by-step explanation:

Each jacket costs $26.50 so x is the variable to depict how many jackets she is buying because it does not tell us in the question. There is a one-time fee of $15.99 so that is added on to the total to find the total cost which is y.
