Calculate the area of trapezium CDEF.

Answer:

(8)(21) = 12x

Step-by-step explanation:

(8)(12) = 21x

(8)(21) = 12x

(12)(8) = 12x

(12)(21) = 8x

Opposite : Adjacent

12 in : 21 in

Opposite : Adjacent

8 in : x in

Equate both ratios to solve for x

12 : 21 = 8 : x

12 / 21 = 8 / x

Cross product

(12)(x) = (21)(8)

12x = 168

x = 168 / 12

= 14

x = 14

Answer:

20.25

Step-by-step explanation:

i think its asking for the long side

the pythagorean theorem states that in a right triangle a^2+b^2=c^2

a is 19

b is 7

c is the long side

19^2= 361

6^2= 49

361+49=410

410 =c^2

square root of 410 = ~20.25

Answer:

[tex]hypotenuse = \sqrt{ {19}^{2} + {7}^{2}} \\ = \sqrt{361 + 49} = \sqrt{410} \\ = 20.25[/tex]

20.25 is the right answer.

Step-by-step explanation:

here you go mate

step 1

3х + 4 = 9x + 3 ​ equation

step 2

3х + 4 = 9x + 3 ​ simplify

-6x+4=3

step 3

−6x+4=3  subtract 4 from both sides

−6x+4(-4)=3(-4)

-6x=-1

step 4

x=[tex]\frac{1}{6}[/tex]

Answer:

[tex]d = -\dfrac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]6d-\dfrac{11}2=2d-\dfrac{13}{2}[/tex]

Required

Solve for d

[tex]6d-\dfrac{11}2=2d-\dfrac{13}{2}[/tex]

brainliest plsssss

Step-by-step explanation:

−2−3n

= −2 + −3n

Step-by-step explanation:

1. f(x) = 6x - 14

Slope is the coefficient of x

Slope = 6

2. f (x) =6x+ 9 +x

f(x) = 7x +9

Slope = 7

3. The last option because it is not a line.

4. The third option. x and y do not get multiplied in linear equations.

5. The last option.

the first one is y=x

the second one is y =-x

the third one is y=0x - 2

the last one is wrong because if x is - 1 or - 2 twice, it should still give the same vue for y.

I hope this helps.

Answer:

first u gotta take a step then kidnap a kid from brazil and then solve the problem

Step-by-step explanation:

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Her son washed the most laundry.

The number of laundries that need to be washed is 46.5%.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

The number of laundries Mr. Barnes washed = 2/7.

This means,

= 2/7 x 100

= 28.5%

The number of laundries her son washed = 1/4.

This means,

= 1/4 x 100

= 25%

We see that,

Her son washed the most laundry.

The number of laundry needs to be washed.

= 100% - (28.5% + 25%)

= 100% - 53.5%

= 46.5%

Thus,

Her son washed the most laundry.

The number of laundries that need to be washed is 46.5%.

Answer:

-2 < 12

Step-by-step explanation:

12 is bigger than -2.

Step-by-step explanation:

1500(1+2.5/100)^3

or do 100+2.5=102.5

102.5÷100=1.025

1500×1.025^3

Given:

The function is

[tex]y=3x[/tex]

Domain of the function is {9, 15, 18, 21, 27}.

To find:

The range of the function.

Solution:

We have,

[tex]y=3x[/tex]

Domain is set of input (x-values) and range is the set of output (y-values).

Domain =  {9, 15, 18, 21, 27}

For x=9,

[tex]y=3(9)=27[/tex]

For x=15,

[tex]y=3(15)=45[/tex]

For x=18,

[tex]y=3(18)=54[/tex]

For x=21,

[tex]y=3(21)=63[/tex]

For x=27,

[tex]y=3(27)=81[/tex]

So, the y-values are 27, 45, 54, 63, 81.

Therefore, the range of the function is {27, 45, 54, 63, 81}.

Note: Options are not in proper form.

Answer:

y=x-4

Step-by-step explanation:

Slope intercept form is y=mx+b (m=slope and b=y intercept)

so the equation would be y=1x-4 but you should simplify to y=x-4

Answer:

[tex]\huge\boxed{y= \frac{r-p}{t-q}}[/tex]

Step-by-step explanation:

In order to solve for y in this equation, we can algebraically manipulate it to isolate y one one side of the equation.

Step 1: Subtract [tex]p[/tex] from both sides of the equation.

Step 2: Factor out the common term [tex]y[/tex] from the left side

Step 3: Divide both sides by [tex]t-q[/tex]

Answer:k = 2/3

Step-by-step explanation:

When a variable y directly relates to another variable x, we can say:

y=kx

Given the equation, we can say

3y=2x

y= 2x/3

Putting the value of y from above discussion

kx = 2x/3

x is being cancelled on both sides of equation

k= 2/3

Answer:

the red skittles be 44 and yellow skittles be 17

Step-by-step explanation:

The computation of the number of each color are in the bowl is as follows;

Let us assume the red skittles be y

And, the yellow skittles be x

The first equation is

x + y = 61

And, the second equation is

y = 2x + 10

Now put the second equation in the first equation

x + 2x + 10 = 61

3x = 51

x = 51 ÷ 3

= 17

And, y = 2 (17) + 10

= 34 + 10

= 44

Hence, the red skittles be 44 and yellow skittles be 17
