Answer:

5 5/7

Step-by-step explanation:

Step-by-step explanation:

If the figure is triangle then,

Let PR be x

So,

PQ+QR+PR= 180 (Sum of all the angles of the triangle)

Therefore,

6x+25+16-3x+x=180

4x+36=180

4x= 180/36

x= 144/4

X= 36

NOW,

PQ= 6x+25

= 6(36)+25

= 216+25 = 241= PQ.

QR = 16-3x

= 16-3(36)

= 16-108

= -92

PR = 36

hope it helps

Answer:

-17

Step-by-step explanation:

First, let's see what the value of w is, by solving -5w - 5 = 5.

-5w - 5 = 5            Add 5 on both sides.

-5w = 10                Divide -5 on both sides.

w = -2

Now, we know that w is equal to -2, let's plug it in to find the value.

9(-2) + 1                 Distribute.

-18 + 1                    Add.

-17

Answer:

A. The weight of the apples is a function of their cost.

Step-by-step explanation:

In the graph it shows the more the apples weight the cost increase, therefore A is your answer.

B is the answer for this question due to the value of root and that's is root under 20

Answer:

Point B represents the location of

[tex] \sqrt{20} [/tex]

Step-by-step explanation:

As the value of under root 16 is 4 and the value of under root 25 is 5

So the location of under root 20 will be in between 4 and 5 on the number line

Step-by-step explanation:

Start with whichever arrow starts from 0

Answer:

x=0

x=12

Step-by-step explanation:

Set up the equation

x^2-12x=0

Factor out x

x(x-12)=0

Set each factor equal to 0.

x=0

(x-12)=0

x=12

Answer:

he quotient has a remainder of 4.

The quotient has a remainder of 14.

The quotient has no remainder.

The quotient has a remainder of 12.Step-by-step explanation:

Answer:

The square root of 2 is between 1 and 2, so radical 2 is about 1.4.

Step-by-step explanation:

You can plot a 1 on the very left and a 2 on the very right of the number line.

Since there is no formal square root of 2, you have to estimate.

It has to be less than 2 because if you multiply 2 * 2 you get 4 and that's too big; we want to get 2.

It also has to be greater than 1 because 1 * 1 = 1 and that's too low.

I would estimate it to be right before the middle line.

the answerrrrrrr is

356.85

Answer: 3 months

Step-by-step explanation:

Answer:

3 1/2 months (Someone please check my math)

Step-by-step explanation:

We can set up this problem by making an equation.

(2900-1200-200-5%)(x)=5000

(1500-5%)(x)=5000

(1425)(x)=5000

5000 divided by 1425 equals 3.50...

My answer would be 3 1/2 months but I could be wrong.

Answer:  (1.125,-0.25)

Step-by-step explanation:  The point that is the same for both equations is the point where they intersect.  It appears from the graph to be around (1,0).  We should confirm this by deriving the equation for each line and then solving them.  Use the standard format:  y = mx+b, where m is the slope and b the y-intercept.

I calculate the 1st line (angled down to the right) to have a slope (m) of -2 [y drops 2 for every increase of 1 for x).  The y intercept is 2 (b).  This equation would be y = mx+b, or y = -2x + 2.

The second line has a positive slope of 2/3 and a y intercept of -1, y = (2/3)x-1

Set these two equations equal to each other and solve for x.

-2x+2=(2/3)x-1

x = 1.125

Use that value of x to solve for y:  y = -0.25

The point of intersection is therefore (1.125, -0.25)

Answer:  the absolute value of -5, 0.25, 0.25, -2.5, -1 1/5, -4
