Y = 500x + 38000 would be the first step, as that sets up the equation. Then, 45500 = 500x + 38000 would be the next. Third would be 7500 = 500x, as that is where we subtract 38000 from both sides. Then, finally the answer is x = 15.
To put it in a list
1. Y = 500x + 38000
2. 45500 = 500x + 38000
3. 7500 = 500x

Answers

Answer:

Pretty sure it's 6.4 lbs

Step-by-step explanation:

We have to set up a proporion. So ?/40 and 16/100 because 16% of 100. Since we can't cross multiply 100 and ?, we have to cross multiply 16 × 40 = 640. We have 100 leftover, so 640÷100=6.4

Ok so I did the work and it’s definitely 6.4

20+60+100=180 so its not c

Answer:

D

To be a triangle, you have to have 180 degrees. if you add up all of the sides, it should give you 180. If it doesn't, it isn't a triangle. I hope that helped! :)

m22 + m23 = 180°

m2l + m23 = 180°

Answers

Answer:

Because linear pairs of angles are  supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.

Because angles that are  supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.

Step-by-step explanation:

The correct question is attached.

Linear pairs angles are angles which are formed from the intersection of two lines and they are adjacent to each other. Linear pair angles are supplementary.

If angles are supplementary to the same angle, then they are congruent.

∠1 and ∠3 are vertical angles

∠1 and ∠2 form linear pairs while ∠2 and ∠3 form linear pairs. Therefore:

m∠1 + m∠2 = 180° (linear pair angles are supplementary)

m∠2 + m∠3 = 180° (linear pair angles are supplementary)

Hence using transitive property of equality:

m∠1 + m∠2 = m∠2 + m∠3

Using subtraction property of equality by subtracting m∠2 from both sides gives:

m∠1 = m∠3

∠1 ≅ ∠3 (vertical angles are congruent)

Because linear pairs of angles are  supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.

Because angles that are  supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.

Triangle A) perpendicular cross section of a cylinder
Rectangle B) shape created when a right triangle is rotated about the y-axis
Circle C) shape created when a rectangle is rotated about the y-axis
Cylinder D) parallel cross section of a sphere
Cone E) perpendicular cross section of a pyramid

Answers

Answer:

Step-by-step explanation:

Perpendicular cross section of a pyramid -------   triangle.  

Imagine you cut pyramid like that. Height of pyramid would be height of your triangle. and sides of pyramid would be sides of triangle.

Perpendicular cross section of a cylinder -------  rectangle

diameter of a base of cylinder would be one side of rectangle and height of cylinder would be other side of rectangle. (pair of sides)

parallel cross section of a sphere ------ circle

when you cut sphere a side would appear with shape of circle.

shape create....    -----    cylinder.  

one side of rectangle would be high of cylinder and other would be radius of it.

last one is cone.  If you place right angle in coordinate beginning (0.0) and one of shorter sides to lie on y axis other would be on x axis. when rotated you get cone.

Solve the system by substitution.
x= -5y - 6
5x – 3y = -2
What’s is the solution?

Answers

The value of x is -1 and value of y is -1.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equations are

x+5y=-6...(1)

5x – 3y = -2...(2)

Multiply equation 1 with 5

5x+25y=-30..(3)

Subtract equation 2 and equation 3

5x-3y-5x-25y=-2+30

-28y=28

Divide both sides by 28

y=-1

Now plug in y value in equation 1

x=5-6

x=-1

Hence, the value of x is -1 and value of y is -1.

A class of 25 children is having a pizza party. Each child will eat 3/8 of a pizza. How many pizzas do they need to order?

Answers

A. 8 pizza pies at 10 pc. per pie = 80 available pieces

B. Let X be the number of children. Number of pieces eaten = 5 per child = 5X.

c. 22 pieces are left over.

D. Combine line A and line C. Total number of pieces eaten = 80 original minus 22 left over. Result 58 pieces were eaten by X children: 58 = 5X.

E. Solve the equation 58 = 5X by dividing both sides by 5.

WHOOPS! Is this a trick question? Solving the above results in the answer that there are 11.6 children at the party. Hmmm. That 0.6 child is a question mark for me.

Looks like someone miscounted the pizza slices. Or omitted some pertinent information. But, I’m sure there is a logical answer.

3/8 * 25 = 9.375

You can't buy .375 of a pizza so you round it up and get 10.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Chrissie says that the equation of the line shown on the graph is y = 1/2x -5. George says that the equation of the line is y = 1/2x + 5.

From the graph, the y-intercept of George's equation is positive then George's equation is correct.
