Answers

Answer:

See below

Step-by-step explanation:

Part A

Standard form is Ax + By = C

x - price of adult tickets, y - price of child tickets, the equation in the standard form is:

15x + 9y = 90 ⇒ 5x + 3y = 30Part B

y-intercept is obtained when x = 0

15*0 + 9y = 909y = 90y = 10

It represents the amount of child tickets if no adult tickets sold

x-intercept is obtained when y = 0

15x + y*0 = 9015x = 90x = 6

It represents the amount of adult tickets if no child tickets sold

Part C

Converting the equation into slope-intercept form of y = mx + b

5x + 3y = 303y = -5x +  30y = -5/3x + 30/3y = -5/3x + 10Part DThe slope is -5/3. It represents the negative ratio of ticket prices

The slope is -5/3 that the answer

2b + 7z when b = 3, z = 4.

please show your work and make sure you get the answer right thank you

Answers

Answer:

34

Step-by-step explanation:

2b + 7z when b = 3, z = 4

2*3 = 6

7*4 = 28

28 + 6 = 34

Hope this helps!

basically you just plug it in!! so since B is 3, replace 2B as 2(3) and same with Z. That would make the equation

2(3)+7(4)

6 + 28
34

Answer:

Step-by-step explanation:

First thing first, we need to alter this equation is y is the value we are fining. we can do this by adding 10x to both sides. our new equation is

y=10x+4

Now, all we have to do is plug in out x values in order to get our y values and complete the table.

Example, 10x2 is 20 and 20+4 is 24 so when x is 2, y is 24

Suppose you have $150 to buy birthday gifts for two of your friends. If you spend $83.65 on the first gift, how much money do you have left for the second gift?

Answers

150-83.65= 66.35. You would have $66.35 to spend on the second gift

Answer:

$66.35

Step-by-step explanation:

Since you have $150 in total and you already spent $83.65, we need to subtract to figure out how much money we have left. So 150 - 83.65 is equal to 66.35. This means that you can use $66.35 on the second gift.

Answers

Answer:

Line up the numbers with the letters.

Step-by-step explanation:

When these two line up there is your answer

So the first thing you want to do is graph the y-intercept which would be on the y-axis. So the y-intercept is -5 i believe and after you graph that look at your slope which is 3/2 this is a positive slope so the line will be moving upwards left to right. So slope is rise/run so rise is 3 and run is 2. So we go from our y-intercept (-5) and move up three points and right two. That is where we will place the next point. Keep on doing this and you should be able to connect then to form a line. I hope this helped! Please look at other sources too to confirm I don’t want you to get it wrong!

Look at the picture of a scaffold used to support construction workers. The height of the scaffold can be changed by adjusting two slanting rods, one of which, labeled PR, is shown:

A support structure is shown in which a right triangle PQR is formed with the right angle at Q. The length of PQ is shown as 14 feet, and the length of QR is shown as 8 feet..

Part A: What is the approximate length of rod PR? Round your answer to the nearest hundredth. Explain how you found your answer, stating the theorem you used. Show all your work. (5 points)

Part B: The length of rod PR is adjusted to 17 feet. If width PQ remains the same, what is the approximate new height QR of the scaffold? Round your answer to the nearest hundredth. Show all your work. (5 points)

Answers

Answer:

A). PR = 16.13 ft

B). QR = 9.64 ft

Step-by-step explanation:

Part (A).

From the figure attached,

ΔPQR is a right triangle,

m(PQ) = 14 ft

m(QR) = 8 ft

By applying Pythagoras theorem,

Hypotenuse² = (Leg 1)² + (Leg 2)²

(PR)² = (PQ)² + (QR)²

(PR)² = (14)² + (8)²

PR = √260

    = 16.125

    ≈ 16.13 ft

Part (B).

If PR = 17 feet

and PQ = 14 feet

By applying Pythagoras theorem in ΔPQR,

PR² = PQ² + QR²

(17)² = (14)² + (QR)²

(QR)² = 289 - 196

QR = √93

    = 9.644

    ≈ 9.64 ft

Answers

The inside angles of a 4 sided shape when added together equal 360.

X = 360 - 50-130-120

X = 60 degrees.

Answer:

60°

Step-by-step explanation:

In a four-sided shape, the total angle measures 360°.

So,

50 + 130 + 120 + x = 360

300 + x = 360

x = 360 - 300

x = 60°

if you are solving for d the answer is
d= .5
but if you just have to simply the answer is 4d-2

you have to distribute the 2 so to get 4d-2 then if your solving for d you add the 2 to both sides and then divide by 4 on each side to get the value for d

Explain two ways you could solve 24=6(-3+x)

Answers

You could either divide the 6 on each side and have 4=-3+x, so x=7, or you could distribute the 6 into the expression, so 24=-18+6x. Then 42=6x, and x=7.
24=6(-3+x) expand
24= -18 + 6x
42= 6x
7 = x
Or 24=6(-3+ x) divide by 6
4=-3 + x
4+ 3 = x
X=7
