Order of Operations: BPEMDAS Equality Properties

Algebra I

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

5x + 3y = 26

-2y = 6x - 4

Step 2: Rewrite systems

5x + 3y = 26

y = 2 - 3x

Step 3: Solve for x

Substitute: 5x + 3(2 - 3x) = 26Distribute 3: 5x + 6 - 9x = 26Combine like terms: -4x + 6 = 26Subtract 6 on both sides: -4x = 20Divide -4 on both sides: x = -5

Step 4: Solve for y

Define: -2y = 6x - 4Substitute: -2y = 6(-5) - 4Multiply: -2y = -30 - 4Subtract: -2y = -34Isolate y: y = 17

And we have our final answer!

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

We have been given that Three concert tickets cost $45.

To determine the cost per ticket.

Therefore,

45$ = 3 Tickets

For the unit cost of the concert ticket.

45 / 3 = 1 Ticket

1 Ticket = 15

Twenty percent of a mixture of pure milk and water is water. Half a litre of wine is added to one litre of the mixture of water and milk and throughly mixed. What percentage of the new mixture is water?

Answers

Answer:

In the new mixture, the percentage of water with respect to its total is 13.33%.

Step-by-step explanation:

Given that in a liter of mixture 20% of it was water and the remaining 80% was pure milk, and that half a liter of wine was added to that liter of mixture, to determine the percentage of water in the new mixture is necessary to perform the following calculation:

20 + 80 + 50 = 150

150 = 100

20 = X

((20 x 100) / 150) = X

2,000 / 150 = X

13.33 = X

Thus, in the new mixture, the percentage of water with respect to its total is 13.33%.

Answer: Nonlinear; power of x is greater than 1 (Bottom right corner)

Explanation:

The equation y = x^2 - 1 is known as a quadratic since the largest exponent here is 2. This equation cannot be written in slope intercept form y = mx+b, so that's why it's not linear. You can also graph y = x^2-1 to get a curved parabola. The graph must be a straight line if you want a linear equation.

Look at the system of equations in the box at
the right. Kevin stated that the equations in this system
have the same slope, so there will be infinitely many
solutions. Does Kevin's statement make sense?

Answers

Answer:

No.

Step-by-step explanation:

No, Kevin’s statement doesn’t make sense. He is correct that since the two equations have the same slope. Thus, they are parallel to each other.

However, since they are parallel, they will never touch. Therefore, there is no solution.

They will be infinitely many solutions if they are parallel and they have the same y-intercept.

Answer:

No it does not make sense

Step-by-step explanation:

If 2 linear equations have the same slope, then they represent two parallel linesParallel lines never cross, so they cannot have any solution

Which of the following explains how ΔBEI could be proven similar to ΔCEH using the AA similarity postulate?

A segment connects points A and D, a segment connects points B and C, a segment connects points I and H, and a segment connects points F and G. Segments AD, BC, FG, and IH all intersect at point E. ∠BEI ≅ ∠CEH because vertical angles are congruent; rotate ΔCEH 180° around point E, then translate point C to point B to confirm∠IBE ≅ HCE. ∠BEI ≅ ∠CEH because vertical angles are congruent; reflect ΔCEH across segment FG, then translate point C to point B to confirm∠IBE ≅ HCE. ∠BEI ≅ ∠CEH because vertical angles are congruent; rotate ΔCEH 180° around point E, then dilate ΔCEH to confirm segment EB ≅ segment EC. ∠BEI ≅ ∠CEH because vertical angles are congruent; reflect ΔCEH across segment FG, then dilate ΔCEH to confirm segment EH ≅ segment EI.

The measures are WS=39, WY=78, WZ=58, ZR=29, ZT=16 and YZ=32

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

Z is the centroid of triangle.

The centroid is the centre point of the object. The point in which the three medians of the triangle intersect is known as the centroid of a triangle.

WR=87 SY=39 and YT=48

We need to find WS,WY,WZ,ZR,ZT and YZ

WS=39

As WS=WR

WY=WS+SY

WY=39+39=78

WZ=58

ZR=WR-WZ

ZR=87-48=29

ZT=16

YZ=YT-ZT

=48-16=32

YZ=32

Hence, the measures are WS=39, WY=78, WZ=58, ZR=29, ZT=16 and YZ=32

Please help The profit P, of a fundraising event can be modeled by the equation p= 50x-2000, where x is the number of tickets sold. What does the 50 in this expression represents?
A. The number of tickets sold
B. The number of people that attended
C. The profit from the event
D. The cost per ticket

Answers

Answer:

D. The cost per ticket

Step-by-step explanation:

You might remember that an equation in the form [tex]y=mx+b[/tex] is in slope-intercept form, where m is the slope and b is any number constant.For this equation, [tex]p=50x-2000[/tex] , y is p, the slope m is 50 and b is -2000The slope tells how much the profit is changing with each ticketSlope simply means "the amount of change"So if we have 2 tickets sold, the profit is [tex]p=50*100-2000=3000[/tex] What about 101? [tex]p=50*101-2000=3050[/tex] So the profit is changing by 50 with every ticketThat means each ticket costs 50 whatever currency It will save you trouble to just remember that in a profit equation, the slope is always the cost per item.
