Answer 1

Answer:

8

Step-by-step explanation:

you want to set it up like this

8/20   and   6/2x-1

then you cross multiply

so 8(2x-1)  = 16x-8

and 20*6 = 120

then you do 120= 16x-8

add 8 to both sides   (you want x by it's self so to get rid of a -8 you have to add 8)

128= 16x  

(divide both sides by 16)

128/16= 8

8=x

Answers

Answer:

5 felt pads.

7 cards.

Step-by-step explanation:

Remark

The total number of items is 12 So let the felt sheets be xLet the cards = y

Equations and Solution

x + y = 12

Now the price is 7.75 that she has to pay for the 12 items. She wants to come back with 0 dollars.

0.5x + 0.75y = 7.75             Multiply this equation by 2

x + 1.5y = 15.50                    write the first equation underneath and subtract.

x +    y =   12

      .5y =  3                          Divide by 0.5

y = 3/0.5

y = 7

So she can get 7 cards.

x + y = 12

x + 7 = 12

x = 12 - 7

x = 5

So she can buy 5 felt pads.

what do I do for this​

Answers

Answer:

The answer is C

Step-by-step explanation:

OK, so you know the equation y = mx + b?

To find the slope, divide rise/run

Since the line is going down, that means the slope is negative.

See which y has x = 0

In this case it’s -1

so it has to be C

C

Step-by-step explanation:

A water tank already contains 56 gallons of water in Baxter begins to fill it. water flows into the tank at a rate of 8 gallons per minute. write a linear equation to model this situation. Find the volume of the water in the sink 5 minutes after Baxter begins filling the tank.

Answers

Answer:

Equation: y = 8x + 56

After 5 minutes, the volume of the water was 96 gallons

Step-by-step explanation:

Use y = mx + b to create the linear equation, where m is the slope and b is the y intercept.

Since the water flows in at 8 gallons per minute, 8 will be the slope. The variable x will represent the number of minutes.

There are already 56 gallons of water in the tank, so b will be 56.

Plug in these values into the equation:

y = 8x + 56

So, the linear equation is y = 8x + 56

Using this, plug in 5 as x to find the volume of the water in the sink after 5 minutes:

y = 8x + 56

y = 8(5) + 56

y = 40 + 56

y = 96

So, after 5 minutes, the volume of the water was 96 gallons
