How can I make this equation into an ordered pair

Mathematics
1 answer:
Novay_Z [31]4 years ago

I'd suggest re-wording your question:
"How do I find the ordered pair (x,y) that solves this system of linear equations?"

One way of doing that would be to substitute y=5x+7 into the other equation:

-3x - 2(5x+7) = -12.  Solve this for x.  Once you have a value for x, subst. that value into y=5x+7 to find the corresponding y value.

Then write the ordered pair (x,y).  That's it.

The school band director has a budget $4,428.00 to spend on the band room, instruments, music, and uniforms. There are four sect
galina1969 [7]

Answer:

The amount of money left for each section to spend from the budget in additional costs if they follow exact of the options is

Option 1 - $497.5

Option 2 - $494.5

Option 3 - $500.5

The image to show the amounts to match to isn't attagged to the question, but these are the answers and they should be matched accordingly.

Step-by-step explanation:

We first calculate the amount left per section after following each of the options.

Budget $4,428.00

Option 1.

Repair and replace uniforms at $564.00 per section and spend $182.00 on music.

There are 4 sections, hence, total amount spent in this option:

4(564) + 182 = $2438

Amount of money left from the budget after spending = 4428 - 2438 = $1990

Amount left per section = (1990/4) = $497.5

Option 2

Repair and replace uniforms at $593.00 per section and spend $78.00 on music.

There are 4 sections, hence, total amount spent in this option:

4(593) + 78 = $2450

Amount of money left from the budget after spending = 4428 - 2450 = $1978

Amount left per section = (1978/4) = $494.5

Option 3

Repair uniforms at $287.00 per section, spend $856.00 for improving the acoustics in the band room, and spend $422.00 on music and repairing instruments.

There are 4 sections, hence, total amount spent in this option:

4(287) + 856 + 422 = $2426

Amount of money left from the budget after spending = 4428 - 2426 = $2002

Amount left per section = (2002/4) = $500.5

STatiana [176]
The answer is 38,016. You have to multiply 4800 by 6 which equals 28,800. then multiple 0.32 times 4800 which equals 1538. multiply 1538 by 6 which equals 9,216 and then add 28,800 which equals it to 38,016.
