help me pleaseeeeeeeeeeeeeee?

The resulting equation after substitution is

5x + 4(-2x + 6) = 3

quite literally you replaced y with what it equals (as said in the second equation)

you then distribute the 4 within the parenthesis

5x + -8x + 24 = 3

You make it easier

5x - 8x +24  = 3

you combine like terms

-3x + 24 = 3

you subtract 24 from both sides

-3x = -21

you divide both sides by -3

meaning x = 7

you then use that value x = 7 and substitude it for the x in the other equation.

That makes the y equation

y = -2(7) + 6

you then solve

y = -14+6

y = 6 - 14

y = -8

Your pay rate is:  

$ 7  per hour

Your friend's pay rate is  :

$ 9  per hour

Explanation:

So if it takes you  8  hours to make  $ 56 , you can just divide the total money earned by the time.  So it would be  56 ÷ 8  which is  7 .

And if takes your friend  4  hours to make  $ 36 , you can divide like we just did . So it would be  36 ÷ 4  which is  9 .

So you make  $ 7  per hour and your friend makes  $ 9 per hour.

Answer:

62 weeks

Step-by-step explanation:

What we need is to represent the ratios in expression

For example if we have 992 gallons and the leaking is 5 gallons per week, the expression for the gallons after every week is

992-5x

x is the weeks

And the other case the expressions is

1240-9x

The question is the weeks for the amount being the same, then every equation can be equal to Y and it represent the same amount

992-5x=y

1240-9x=y

in both the y is the same, then

992-5x=1240-9x

992-1240=-9x+5x

-248=-4x

-248/-4=x

62=X

and that is the weeks we need for the amount being the same in both tanks

Answer:

62 weeks correct me if i'm wrong

Answer:

First answer = 36

Second answer = 9

Third answer =1/4

Step-by-step explanation:

The probability of rolling an even number and then an odd number is 1/4.

Probability is simply the chance of getting an event from a sample space. Total probability of all the outcomes in an experiment will be always 1.

Probability of an event can be found by dividing the number of desired outcomes with the total number of outcomes.

Here two number cubes are rolled. Each number cube has total 6 outcomes.

If the sample space consists of all the outcomes of first and second number cubes,

Size of sample space = 6² = 36

We have to find the probability of rolling an even number on the first cube and then an odd number on the second cube.

There are 3 chances of having an even number for the first cube which are 2, 4 and 6.

There are 3 chances of having an odd number for the second cube which are 1, 3 and 5.

Therefore number of desired outcomes = 3² = 9

Probability (first is even and second is odd) = Number of desired outcomes / Size of the sample space

Probability (first is even and second is odd) = 9/36 = 1/4

Hence the probability of getting an even number on the first number cube and then an odd number on the second cube is 1/4.

Answer:

Step-by-step explanation:

If the original triangle length of Side A to C is 4, then the answer is two. If the original traingle length is Side A to C on the original triangle is 8, then the answer is 1/2.

The scale factor of the dilation is 1/2.

Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object. The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Given:

Before dilation

AC= 8, BC= 10 abd AB= 6

After dilation

AC= 4, BC= 5 and AB= 3

Now, scale factor

Scale factor = Dimensions of the new shape / Dimensions of the original shape.

So,

scale factor = 4/8  or 5/10  or  3/6 = 1/2

Hence, the scale factor is 1/2.
