solve for x 5(4x-5)+3x-1=20

Answer:

[tex]y^{-1} =\frac{1}{2} x-\frac{5}{2}[/tex]

Step-by-step explanation:

Answer:

          x - 5

y = --------------

             2

Step-by-step explanation:

1.  Replace "f(x)" with "y:"  y = 2x + 5

2.  Interchange x and y:  x = 2y + 5

3.  Solve this result for y:

2y = x - 5, or

          x - 5

y = --------------

             2

Step-by-step explanation:

Step 1: Define systems

5x - 2y = 9

3x + 4y = -5

Step 2: Rewrite systems

10x - 4y = 18

3x + 4y = -5

Step 3: Solve for x

Step 4: Solve for y

And we have our final answer!

Answer:

h(-1) = 8

h(-2) = 11

h(-12) = 41

Step-by-step explanation:

h(x) = -3x + 5

h(-1) = -3(-1) + 5 = 3 + 5 = 8

h(-2) = -3(-2) + 5 = 6 + 5 = 11

h(-12) = -3(-12) + 5 = 36 + 5 = 41

Answer:

You divide 2.50 by 5.

So 2.50/5 makes it $0.50 per ounce.

Answer: $0.50 for 1 ounce

Step-by-step explanation:

To find a unit rate, you have to find the cost for one. When we say it's $2.50 for 5 ounces, it's for 5, not 1. So we have to divide by 5.

2.50/5= 0.5 and 5/5=1

Step-by-step explanation:

==============================================

Explanation:

Because S and T are midpoints of segments PQ and QR, we know that ST is a midsegment of triangle PQR. Consequently, this means ST is parallel to PR.

From the same side interior angle theorem, the angles (11x-3) and (5x-9) are supplementary angles. This is only true because of the parallel lines.

So we can say the following:

(angle P) + (angle S) = 180

(5x-9) + (11x-3) = 180

(5x+11x) + (-9-3) = 180

16x - 12 = 180

16x = 180+12

16x = 192

x = 192/16

x = 12

--------------------------

Use this to find angle PST

angle PST = 11x-3

angle PST = 11*12-3

angle PST = 132-3

angle PST = 129 degrees

--------------------------

Optionally we can find angle QPR

angle QPR = 5x-9

angle QPR = 5*12-9

angle QPR = 60-9

angle QPR = 51 degrees

As a check, adding the two angles we found should get us 180

(angle PST)+(angle QPR) = 129+51 = 180

The answer checks out.

C personalities are organized and controlled. They take their time completing tasks accurately, like to research things thoroughly, and are always prepared.  Because they put so much time and effort into everything they do, they hate to be criticized. They are perfectionists at heart and take even the smallest complaint personally.  This makes them extremely difficult to confront. The best way to approach it is to focus on parts of the problem largely out of the C personality’s control or aspects of the problem they might not have considered.  Make it clear that you appreciate all of their efforts and that you’re bringing something to their attention because it’s a variable that they need to have in the equation in the future. No matter what, don’t frame the conflict as a personal attack. If you do, the C personality will likely become resentful and go out of their way to avoid future interactions with you.%%%%%%%%%%%%%%%

Answer:

A. 228.5

B. 10

Step-by-step explanation:

A. Since x represents the number of months, replace x with 6 in the equation. Then multiply 29x6, which equals 174. Then add 174+54.5, which equals 228.5.

B. You need to solve for x by switching the signs in the equation. Set the original equation (29x+54.5) equal to 344.50. To solve for x, first subtract 344.50-54.5, which equals 290 (you subtract because it's the opposite of adding). Then divide 290÷29, which equals 10. You can check your work by replacing x in the original equation with 10, and if you get 344.5, your answer is correct.

Good luck :)

Answer:

Because scientific notation has to be in between 1 and 10, you would need this to be 5.2. Count the spaces and since its getting smaller your exponent is negative.
