Hello from MrBillDoesMath!

Answer:

-30

Discussion:

-3b -3y -3a -3x => (rearrange terms so a,b and x,y together)

-3a - 3b - 3x - 3y => (factor 3 from each term)

-3(a+b) - 3(x+y) => (substitute values provided by problem)

-3(9) - 3(1) =>

-27 - 3 = -30

Regards,

MrB

Lee buys a computer and a printer for $2,028 The printer costs 30% the price of the computer. What is the price of the computer?

lisov135 [29]

Answer: $1,560

Step-by-step explanation:

Assume the computer's price is x.

This means that expressing the printer in terms of x would be:

= 30% * x

= 0.3x

These two put together represent the cost of $2,028

Expression is:

x + 0.3x = 2,028

1.3x = 2,028

x = 2,028/ 1.3

x = $1,560

Computer was $1,560

Printer was therefore:

= 1,560 * 30%

= $468

combine like terms to simplify each expression. 1: 3/4z(3)+4-1/4z(3). 2: 3.4m+2.4m. 3: 4.2n+5-3.2n. 4: q(5)+q(5)+q(5). 5: 3x+1/4

Temka [501]

Explanation and steps to the expressions are marked in order in the images below.

1. Answer is 3z/2 + 4

2. Answer is 5.8m

3. Answer is n + 5

4. Answer is 15q

5. Answer is 10x + 1/2 + y

6. Answer is 8z + 4.2

The maximum is five images, so I cannot add the last explanation and steps for the last expression.

Solve. Tell whether the equations have all real numbers or no solutions.
