Answer:

BD=13

(This must not be drawn to scale)

Step-by-step explanation:

You have to use the Angle Bisector Theorem to get a ratio.

12/x=27/(x+5)

cross multiply

12(x+5)=27x

12x+60=27x

60=27x-12x

60=15x

60÷15=x

x=4

BD=x+x+5=4+4+5=13

Answer:

-3

Step-by-step explanation:

7(-3x-7y-56)

-21x-49y-392

-3(-7x+10y-1)

21x-30y+3

because the eq. multiplied by 7 is negative, the second eq mus be positive in order to eliminate the x variable. this is why we multiply by a (-). by multiplying the second eq by 3, both eq. will result in a coefficient of 21. one positive one negative allowing the x variable to be eliminated from the problem.

Step-by-step explanation:

ok so the answer for the one after 12x is 8x I think but it would only make sens i dunno the answer to the fraction

Answer and Step-by-step explanation:

Let's solve your equation step-by-step.

−2(x+5)=4

Step 1: Simplify both sides of the equation.

−2(x+5)=4

(−2)(x)+(−2)(5)=4(Distribute)

−2x+−10=4

−2x−10=4

Step 2: Add 10 to both sides.

−2x−10+10=4+10

−2x=14

Step 3: Divide both sides by -2.

-2x/2 = 14/-2

x equals...

x=-7

Answer:

Look just at finding the linear model. Two points. Use price per gallon for x and gallons per hour sold for y. Your two points (x,y) are (2.15,1600) and (2.55,800).

Slope m=%281600-800%29%2F%280.15-0.55%29

m=800%2F0.40

m=2000

Using point-slope form for a line, and the lower-y point,

y-800=2000%28x-2.55%29

highlight%28y=2000%28x-2.55%29%2B800%29

Answer:

adjust city gallons to 3 gallons and freeway to 7 gallons

make your line in the chart:

3   |  10-3 = 7   |   3(25) = 75   |   7(40) = 280   |   75 =280 =355   |   355   |   yes

Step-by-step explanation:

x = city gallons

y = freeway gallons

x+y = 10        then y = 10-x

25x+40y = 355

substitute for y

25x+40(10-x) = 355

25x+400-40x = 355

-15x+400 = 355

subtract 400 from each side

-15x = -45

divide both sides by -15

-15x/-15 = -45/-15

x = 3 gallons

y = 7 gallons

Answer:

[tex]F = 1.8C + 32[/tex]

Step-by-step explanation:

Given

The attached table

Required

The relationship between both temperatures

This implies that we calculate the table equation

First, we calculate the slope (m)

[tex]m = \frac{F_2 - F_1}{C_2 - C_1}[/tex]

Where:

[tex](C_1,F_1) = (0,32)[/tex]

[tex](C_2,F_2) = (20,68)[/tex]

So, we have:

[tex]m = \frac{68 - 32}{20 - 0}[/tex]

[tex]m = \frac{36}{20}[/tex]

[tex]m = 1.8[/tex]

The equation is then calculated using:

[tex]F = m(C - C_1) + F_1[/tex]

This gives:

[tex]F = 1.8(C - 0) + 32[/tex]

[tex]F = 1.8(C ) + 32[/tex]

[tex]F = 1.8C + 32[/tex]

Answer:

THE NUMBERS ARE 10 AND 5

Step-by-step explanation:

LET THE ANOTHER NUMBER BE X THEN

ONE NUMBER = X - 5

BY THE QUESTION

X - 5 + X = 15

2X = 15 + 5

2X = 20

X = 10

X - 5 = 10 - 5 = 5

Answer:

hi 5 and 10 is required no.

let no. be x

another no.be x+5

Step-by-step explanation:

sum=15

x+x+5=15

2x=15-5

2x=10

x=10/2=5

x+5=5+5=10

Answer:

b) 0.333

Step-by-step explanation:

there are 6 options that you can get when you roll a dice. 1, 2, 3, 4, 5, 6. if you want to get a 3 or a 5, that means you want 2/6 possible outcomes. 2/6 is 0.333

Step-by-step explanation:

"Write an expression to show k less than 10"

"less than" means that the number is being subtracted from a different number.

This means that "10" is being subtracted from "k"

Thus,

k - 10 is the appropriate expression for the statement, "k less than 10"

ANSWER:   k - 10

Answer:

Hi liddywiddy, sorry you had to wait so long

There are 20 teachers in all

Step-by-step explanation:

the ratio 3:2 is now 12:x

12 / 3 = 4

so the multiplier is 4

now:

4x2 = 8

Next we add them: 12+ 8 = 20

Answer:

20 teachers in all

Step-by-step explanation:

12 / 3 = 4,

4 * 2 = 8,

so 12 + 8 = 20

Answer:

$150

Step-by-step explanation:

90/60=1.5 tthat means 1% of the bike costs $1.50. You ar trying to find 100% so multiply by 100. 1.5x100=150

Answer:

$150

Step-by-step explanation:

You can divide the 90 by 0.60 to get 150. You can check again by multiplying 150 by 0.6 to get 90, which Victor has 60% of the total (being 150)

Hope this helps!

Answer:

geometric, with a common ratio of 1/2

Step-by-step explanation:

The sequence is geometric because you get successive trems by multiplying the previous term by a certain constant, the 'common ratio'. (If you got each successive term by adding or subtracting  the same constant number each time, that would be an arithmetic sequence.)

In this case, it looks like you get each successive term when you multiply the previous term by 1/2.

Thus, the common ratio is 1/2.

Answer:

[tex]H = 3x^2y[/tex]

Step-by-step explanation:

Given

[tex]V = 36x&^6y^8[/tex]

[tex]L = 4x^3y^5[/tex]

[tex]W = 3xy^2[/tex]

Required

Find the height of the prism

Volume (V) is calculated as:

[tex]V =LWH[/tex]

Substitute values for V, L and W

[tex]36x^6y^8 =4x^3y^5 * 3xy^2 * H[/tex]

Make H the subject

[tex]H = \frac{36x^6y^8}{4x^3y^5 * 3xy^2}[/tex]

[tex]H = \frac{36x^6y^8}{4*3x^3*x*y^5y^2}[/tex]

[tex]H = \frac{36x^6y^8}{12x^4*y^7}[/tex]

Divide:

[tex]H = 3x^{6-4}y^{8-7}[/tex]

[tex]H = 3x^2y[/tex]

The height of the prism is: [tex]3x^2y[/tex]
