Step-by-step explanation:

A = ½ h (b₁ + b₂)

Multiply both sides by 2:

2A = h (b₁ + b₂)

Distribute the h:

2A = h b₁ + h b₂

So the second option is not correct.

Instead of distributing, divide by h:

2A/h = b₁ + b₂

Subtract b₂ from both sides:

b₁ = 2A/h − b₂

Third option is correct.

Next, use common denominator to combine.

b₁ = 2A/h − h b₂/h

b₁ = (2A − h b₂) / h

Factor out 2.

b₁ = 2 (A − ½ h b₂) / h

Fourth option is correct.

Answer:

x + 3 + [tex]\frac{13}{x-3}[/tex]

Step-by-step explanation:

Using long division

                  x + 3  ← quotient

        --------------------------

x - 3 | x² + 0x + 4

          x² - 3x    ↓

        ------------------------

                3x + 4

                 3x - 9

        -----------------------

                        13 ← remainder

Thus

[tex]\frac{x^2+4}{x-3}[/tex] = x + 3 + [tex]\frac{13}{x-3}[/tex]

Answer:

y=x*6

Step-by-step explanation:

it is y=x*6 because the y axis is every x's six times.

Answer:

y=6x

Step-by-step explanation:

Frist, you are going to use y=mx+b

M= the slope of the line.

B= the y-intercept( where the line crosses the y-axis).

Slope= [tex]\frac{Rise}{Run} =\frac{30}{5}[/tex] the you simplify it to [tex]\frac{6}{1}[/tex]= 6

Now, you plug in your equation for m.

y=6x+b

Y-Intercept= where the line crosses the y-axis.

In this case it is at 0. Now plug it in.

y=6x+0

Whenever your "b" is 0 you don't need to add +0 in your equation.

Answers

Answer:

14.99s-15g

Step-by-step explanation:

Jemila has $10, $5, and $1 bills in her piggy bank. Their total value is $63. If she has two more $5 bills than $10 bills, and three more $1 bills than $5 bills, how many of each bill does Jemila have?

Answers

Answer:

She has 3 $10 bills, 5 $5 bills and 8 $1

3 times 10= $30

5 times 5 = $25

8 times 1 = $8

$30 + $25 + $8 = $63

A system of equations is a group of equations that can be solved simultaneously. Here we can find one that allows us to solve the given question.

We will see that: Jemila has 8 $1 bills, 5 $5 bills, and 3 $10 bills.

First, let's define the variables:

x = number of $1 bills in the piggy bank.y =  number of $5 bills in the piggy bank.z =  number of $10 bills in the piggy bank.

Then the total amount of money in the piggy bank is:

$1*x + $5*y + $10*z

And we know that the total value is $63, then one equation is:

$1*x + $5*y + $10*z = $63

We also know that she has two more $5 bills than $10 bills, then:

y = z + 2

We also know that she has three more $1 bills than $5 bills, then:

x = y + 3

So  our system of equations is:

$1*x + $5*y + $10*z = $63

y = z + 2

x = y + 3

To solve this, we need to isolate one of the variables in one of the equations. We can see that some variables are already isolated, like on the second or third equations.

For example, we can replace the second equation into the first and third ones:

$1*x + $5*y + $10*z = $63

x = y + 3

$1*x + $5*(z + 2) + $10*z = $63

x = (z + 2) + 3

Now we can simplify these to get:

$1*x + $15*z + $10 = $63

x = z + 5

Now we can replace the second equation on the first one:

$1*x + $15*z + $10 = $63

$1*(z + 5) + $15*z + $10 = $63

Finally, we can solve this for z.

$16*z + $5 + $10 = $63

$16*z = $63 - $15

$16*z = $48

z = $48/$16 = 3

z = 3

Now that we know the value of z, we can use it in the equations:

x = z + 5 = 3 + 5 = 8

y = z + 2 = 3 + 2 =5

Then the solution is:

x = 8y = 5z = 3

Then Jemila has 8 $1 bills, 5 $5 bills, and 3 $10 bills.

Point V is on line segment \overline{UW}

UW

. Given UV=6,UV=6, UW=5x,UW=5x, and VW=4x-1,VW=4x−1, determine the numerical length of \overline{VW}.

VW

.

Answers

Answer: VW = 19

Step-by-step explanation: The segment UW has a point V between them, so:

UV + VW = UW

6 + 4x - 1 = 5x

4x + 5 = 5x

x = 5

The numerical length is

VW = 4x - 1

VW = 4(5) - 1

VW = 19

The measure, numerically, of VW is 19

You want to paint a piece of pottery at an art studio. The total cost is the cost of the piece plus an hourly studio fee. There are two studios to choose from. For studio a: The vase is $10 and the studio fee is $8 per hour. For studio b: The vase is $16 and the studio fee is $6 per hour. After how many hours of painting are the total costs the same at both studios?

Answers

Answer:
3 hours

Explanation:
1) Set an expression for each of the studios we can set out variable as h for hours because that is the unknown value.

Studio A: 10+8h
Studio B: 16+6h

To find out how many hours would pass for their costs to equal each other, we have to make them literally equal each other.

10+8h=16+6h

Now that we have an equation, we can start solving.

10+8h=16+6h
Combine like terms
10-16=6h-8h
-6=-2h
2h=6
Divide both sides by 2 to isolate h
2h/2=6/2
h=3
