4x - 3y = -28<br>x + 5y = 39 cant seem to be able to figure the answer for this

Rus_ich [418]

value of x = -1 and value of y=8

Step-by-step explanation:

We need to solve the system of equations:

$4x - 3y = -28\,\,\,(1)\\x + 5y = 39\,\,\,(2)$

Multiply eq(2) with 4 and subtract with eq(1)

$4x-3y=-28\\4x+20y=156\\-\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\\--------\\-23y=-184\\y=\frac{-184}{-23}\\y=8$

So, value of y=8

Now, finding value of x by putting value of y in equation 2

$x+5y=39\\x+5(8)=39\\x+40=39\\x=39-40\\x=-1$

So, value of x = -1

value of x = -1 and value of y=8

Ella practices piano for 45 minutes she spends m minutes longer working on her homework than she does practicing the piano

babymother [125]

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but let's assume that you want to know the amount of time that she spends working on her homework.

Since we are informed that Ella practices piano for 45 minutes and that she spends m minutes longer working on her homework than she does practicing the piano, the expression to get the number of minutes that she uses on her homework will be:

= 45 + m

For example let's say that she spends 7 minutes more in her homework. Therefore, the total minutes spent on the homework will be:

= 45 + 7

= 52 minutes

Ava’s aquarium is 95% filled with water. The tank holds 1,120 gallons of water. Which is the remaining number of gallons of wate

Stels [109]

Answer:

The aquarium needs 56 more gallons to be completely filled.

Step-by-step explanation:

To get the amount remaining you have to first divide 1120 by 100

1120/100=11.2

Then multiply it by 95

11.2*95=1064

You take the maximum amount (1120) and subtract the amount in the tank (1064) to get the amount left.

1120-1064= 56

With 56 gallons as your final answer.
