Answer

QR= PQ= PR

18x+1= 24x-17

18x-24x= -17-1

-6x= -18

x= 3

QR= 24(3)-17= 55

PQ= 18(3)+1= 55

PR= 15(3)+10=55

Answer:

The value of x is 3. The length of PQ, QR and PR are 55.

Step-by-step explanation:

Given that the lengths in an equilateral triangle are all the same. We can assume that PQ = QR = PR. So we can choose any 2 lengths and compare it :

[tex]PQ = QR[/tex]

[tex]18x + 1 = 24x - 17[/tex]

[tex]1 + 17 = 24x - 18x[/tex]

[tex]6x = 18[/tex]

[tex]x = 18 \div 6[/tex]

[tex]x = 3[/tex]

Next, we have to substitute x = 3 into the expressions :

[tex]PQ = 18(3) + 1 = 55[/tex]

[tex]QR = 24(3) - 17 = 55[/tex]

[tex]PR = 15(3) + 10 = 55[/tex]

Answer:

ab = 42

Step-by-step explanation:

4x + 6 + 7x + 15 = 120

combine like terms

11x + 21 = 120

subract 21 from both sides

11 x = 99

x = 9

plug in to double check 9 in 4x + 6 + 7x + 15

meaning 4 times 9 + 6 + 7 times 9 + 15

36 + 6 + 7 times 9 + 15

Then simplify,

42 + 7 times 9 + 15

Then simplify again,

42 + 63 + 15

Then simplify one last time,

42 + 78

and your answer is

120

meaning the X is right so now plug in the X in 4x +6

and your answer is 42

Answer: 35 dollars

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

Work Shown:

100 cents = 1 dollar

1 cent = 0.01 dollar (divide both sides by 100)

3500 cents = 35 dollars (multiply both sides by 3500)

------

A shorter way is to divide 3500 over 100 to get 3500/100 = 35 dollars.

Answer: 35.00 dollars

Step-by-step explanation:

Answer:

17

Step-by-step explanation:

The length of line AB is 17 units which is one side of a triangle.

A triangle is a closed 2D figure formed by joining three non-co-linear points. By the property of sides, triangles are of three types they are:- Equilateral triangle, Isosceles triangle, and scalene triangle.

We know the length of two given pairs of points can be determined by the distance formula which is [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex].

Given are the points of the vertices of a ΔABC are A(-8, -10), B(9, -10), and

C(9,-3).

∴ The length of line AB is,

= [tex]\sqrt{(9 + 8)^2 + ( -10 + 10)^2}[/tex] units.

= [tex]\sqrt{17^2}[/tex] units.

= 17 units.

Answer:

4/75

Step-by-step explanation:

you will get 5 and 1/3 percent equals (5 + 1/3) / 100 which is equal to 5/100 + (1/3) / 100 which is equal to 5/100 + 1/300. place both fractions under a common denominator. you will get 5/100 + 1/300 = 15/300 + 1/300 = 16/300. simplify the fraction to get 16/300 = 8/150 = 4/75

Answer:

x= 28

Step-by-step explanation:

The angles both sum up to 180°. So, the equation would be: 39+(5x+1)= 180.

Step 1- Add common numbers.

(39+1)+5x= 180

40+5x= 180

Step 2- Subtract 40 to both sides.

40+5x= 180

-40          -40

5x= 140

Step 3- Divide both sides by 5.

5x= 140

5     5

Answer:

Step-by-step explanation:

From the given information:

suppose, the total number of people = n

Thus, the percentage of people believe in high school = 53% = 0.53

= n × m

The poll also let us understand that the number of people falls in margin error.

= ±n × M.O.E

where;

M.O.E = margin of error = ±5%

∴

the number of people falls in margin error. = ±n × 0.05 = 0.05 n

Thus, we can posit that the greatest percentage of people think for highschool was:

[tex]( \dfrac{0.53 n + 0.05 n}{2}) \times 100= 54%[/tex]

However, the least percentage of people think for highschool was:

[tex]\mathbf( \dfrac{0.53 n - 0.05 n}{2}) \times 100= 48 \%}[/tex]

Answer: area = 0.1 m^2

Circumference = 0.8 m

Step-by-step explanation:

1 in = 0.0254 m

5 in = 0.0254 m × 5

5 in = 0.127 m

r = 0.127 m

Area of the circle = π r^2

= π × 0.127^2

= 0.05 m^2

=0.1 m^2

Circumference of the circle = 2 π r

= 2× π × 0.127

= 0.798 m

= 0.8 m

Answer:

Step-by-step explanation:

1. area of a circle = πr²

2. circumference of a circle = 2πr

where diameter = 10 in.

                radius = 10 / 2 = 5 in

1. area of a circle = π(5)²

                            = 78.5 in²

2. circumference of a circle = 2πr

                                              = 2π(5)

                                             = 31.4 in

Answer:The temperature dropped 12 degrees Fahrenheit total

Step-by-step explanation: The temperature dropped 2 degrees per 1 hour for 6 hours, so you would multiply 2 (degrees per hour) by 6 (hours the temperature dropped). 6 x 2 = 12

The total number of degrees the temperature changed in the 6 hours is 12°F.

Here,

The temperature dropped 2°F every hour for 6 hours.

We have to find,

The total number of degrees the temperature changed in the 6 hours.

What is Degree in Fahrenheit?

Fahrenheit is a scale for measuring temperature, in which water freezes at 32 degrees and boils at 212 degrees. It is represented by the symbol ° F.

Now,

The temperature dropped 2°F every hour for 6 hours.

1 hour =  2°F

6 hour = 6 x 2 = 12°F

Hence, The total number of degrees the temperature changed in the 6 hours is 12°F.
