Answer:

y= (C -Ax)/B

x= (C -By)/A

Step-by-step explanation:

Ax+ By = C

solve for y

Subtract AX from each side

Ax+ By - Ax = C-Ax

By = C -Ax

Divide by B

By /B= (C -Ax)/B

y= (C -Ax)/B

solve for x

Subtract By from each side

Ax+ By - By = C-By

Ax = C -By

Divide by A

Ax/A= (C -By)/A

x= (C -By)/A

5. Carla babysits and tutors to make extra money. She babysits for $5 an hour and tutors for $10 an hour.
HACTEHA [7]

Carla can babysit for 5 hours and tutor for 7 hours or babysit for 8 hours and tutor for 5.5 hours

<h3>How to graph the inequality?</h3>

Let x represents hours babysitting and y represents hours tutoring

So, we have:

Earnings = Rate of babysitting * x + Rate of tutoring* y

This gives

Earnings = 5x + 10y

He wants to earn at least $95.

This means that:

5x + 10y ≥ 95

See attachment for the graph of the inequality

From the attached graph, two possible solutions are: (5, 7) and (8, 5.5)

This means that Carla can babysit for 5 hours and tutor for 7 hours or babysit for 8 hours and tutor for 5.5 hours

Hatshy [7]
2 workers, each 8 per hour, for 40hrs a week, so one earns 8 * 40, or 320 bucks, is two workers, so 320 + 320 or 640 bucks

if 2000 is the 100%, how much is 640 in percentage off of it?

well   \bf \begin{array}{ccllll}&#10;amount&\%\\&#10;\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\&#10;2000&100\\ 640&x&#10;\end{array}\implies \cfrac{2000}{640}=\cfrac{100}{x}

solve for "x"
