New type of pump can drain a certain pool in 5 hours. an older pump can drain the pool in 15 hours. how long will it take both p
Leno4ka [110]
New pump:
5 hours = 1 pool
1 hour = 1/5 pool

Old pump:
15h = 1 pool
1h = 1/15 pool

If both work together
1h = 1/5 + 1/15 = 4/15 pool

4/15 pool = 1 hour
1/15 pool = 1/4 hour
15/15 pool = 1/4 x 15 
1 pool = 3.75 hours or 3 hours 45 mins

I need answer on this graphing va substitution.Problem 7 I tried to solve it but not sure that’s correct
Bond [772]

Given the system of equations:

\begin{gathered} 2x+9y=27 \\ x-3y=-24 \end{gathered}

To solve it by substitution, follow the steps below.

Step 1: Solve one linear equation for x in terms of y.

Let's choose the second equation. To solve it for x, add 3y to each side of the equations.

\begin{gathered} x-3y=-24 \\ x-3y+3y=-24+3y \\ x=-24+3y \end{gathered}

Step 2: Substitute the expression found for x in the first equation.

\begin{gathered} 2x+9y=27 \\ 2\cdot(-24+3y)+9y=27 \\ -48+6y+9y=27 \\ -48+15y=27 \end{gathered}

Step 3: Isolate y in the equation found in step 2.

To do it, first, add 48 to both sides.

\begin{gathered} -48+15y=27 \\ -48+15y+48=27+48 \\ 15y=75 \end{gathered}

Then, divide both sides by 15.

\begin{gathered} \frac{15y}{15}=\frac{75}{15} \\ y=5 \end{gathered}

Step 4: Substitute y by 5 in the relation found in step 1 to find x.

\begin{gathered} x=-24+3y \\ x=-24+3\cdot5 \\ x=-24+15 \\ x=-9 \end{gathered}

Answer:

x = -9

y = 5

or (-9, 5)

Also, you can graph the lines by choosing two points from each equation, according to the picture below.

A boogie board that has a regular price of $69 is on sale at a 35% discount. What is the sale price with a 7% tax?
san4es73 [151]
You take 69 * 0.35 and then take that total (24.15) so 60-24.15= 35.85 then to find the tax take 35.85*.07=2.51 so your answer is 35.85+2.51=38.36
