Answer:

By solving the equation with the order of operations, the correct answer is: 80

Hey there! I'm happy to help!

Sum means to add. Let's call our number n.

n+15

We multiply this whole thing by 6.

6(n+15)

And this is -42.

6(n+15)=-42

We use distributive property to undo the parentheses.

6n+90=-42

We subtract 90 from both sides.

6n=-132

We divide both sides by 6.

n=-22.

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:

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:

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

Answer:

I think its $120

Step-by-step explanation:

there are 20 players each having 2 slices. Meaning that they'll need 40 pizzas. each box has 8 slices so theyll need 5 boxes for 40 pizzas. each box costs $24 so that will be $24 x 5 =$120

Answer:

y = -2

Step-by-step explanation:

First, we subtract 2y on both sides:

-24 = 12y

Then, we divide 12 on both sides:

y = -2

Answer:

  m∠MON = 99°

Step-by-step explanation:

A "straight angle" has a measure of 180°, so the two given angles will have that value as their sum.

  m∠MON +m∠LOM = m∠LON

  (8x -13°) +(7x -17°) = 180°

  15x -30° = 180° . . . . collect terms

  x -2° = 12° . . . . . . . . divide by 15

  x = 14° . . . . . . . . . . . add 2°

Now we can find the measures of the angles.

  m∠MON = 8x -13° = 8(14°) -13°

  m∠MON = 99°

_____

Check

m∠LOM = 7x -17° = 7(14°) -17° = 81°

The sum of 81° and 99° is 180°, as it should be.

A linear pair of angles is formed when two lines intersect.

A linear pair of angles must add up to 180°.

angle MON = 8x - 13°

angle LOM = 7x - 17°

The measure of angle MON .

angle MON + angle LOM = 180°

or, (8x - 13°) + (7x - 17°) = 180°

or, 15x - 30°= 180°

or, 15x = 180° + 30°

or, x = 210/15 = 14°

angle MON = 8x - 13°

By putting the value of x, we get

angle MON = 8(14) - 13°

angle MON = 99°

Answer:

14.99s-15g

Step-by-step explanation:

Answer:

Step-by-step explanation:

If B is the midpoint of AC, where the coordinate of the midpoint B is (6, 4) and endpoint C is (9,2). To get the other coordinates A, we will use the midpoint formula;

B(X,Y) = (x₁+x₂/2, y₁+y₂/2)

From the formula;

X = x₁+x₂/2 and Y = y₁+y₂/2

From the coordinaes given X = 6, Y = 4, x₂ = 9 and y₂ = 2

To get x₁:

From X = x₁+x₂/2

6 = x₁+9/2

cross multiply

12 = x₁+9

x₁ = 12-9

x₁ = 3

Similarly for y₁;

Y = y₁+y₂/2

4 = y₁+2/2

cross multiply

8 = y₁+2

y₁ = 8-2

y₁ = 6

Hence the coordinates of the missing endpoint A(x₁,y₁) is (3, 6)

Answer:

Correct answer is A 2:1

Step-by-step explanation:

When writing a unit rate the denominator is always 1

If you want to obtain a unit rate you divide both quantities by the second one.

what is a unit rate?

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

Answer:

2/4

Step-by-step explanation:

half/whole for any number really

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:

-26.75

Step-by-step explanation:

So what I did is I took away the minus sign and put it in front of 8.5 instead so the equation became: 35.25-8.5. Then, I subtracted which gave me 26.75 and then I added the minus sign back in which gave me -26.75.

Answer:

Step-by-step explanation:

10-1.25 = 9.75 (1 hour) 9.75-1.25=8.50(2 hour) 8.50-1.25=7.25(3rd hour)

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.

Answer:

a TENTH OF THE VALUE

Step-by-step explanation:

Answer:1,500 kg • m/s

Step-by-step explanation:

took the quiz

The momentum of the object after the collision is 1500 kg.(m/s).

Momentum is the product of a particle's mass and velocity. As a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force acting on the particle equals the time rate of change of momentum.

As per the given data:

[tex]m_A = 200 kg\\v_A = 15 m/s\\m_B = 150 kg\\v_B = -10 m/s[/tex]

Law of conservation of momentum:

Initial momentum = Final momentum

[tex]m_Av_A + m_bv_b[/tex] =  Final momentum

Final momentum = 200(15) + 150(-10)

= 3000 - 1500

= 1500 kg.(m/s)

Hence, the momentum after collision is 1500 kg.(m/s).

x=40

Step-by-step explanation:

2x+5=85

2x+5-5=85-5

2x=80

\frac{2x}{2}=\frac{80}{2}

x=40

The value of x for the given expression in angles will be 40. The correct option is B.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet. The supplementary angles are defined as when the sum of the angles is equal to 180 degrees.

Given that ∠2 equals (2x+5)degrees and ∠3 equals 85 degrees. The value of x will be calculated by using the supplementary property of angles.

2x+5=85

2x+5-5=85-5

2x=80

x=40

Therefore, the value of x for the given expression in angles will be 40. The correct option is B.
