Answer:

$\boxed{\rm x = 5}$

Step-by-step explanation:

$\rm \cfrac{12}{20} = \cfrac{3}{x}$

Find the missing value.

Solution with work shown:

Use criss-cross multiplication:

$12 \times x = 3 \times 20$
$12x = 60$

Divide both sides by 12:

$\cfrac{12x}{12} = \cfrac{60}{12}$

$x = 5$

Hence,the missing value is 5.

PLZZ HELP ME WILL GIVE BRAINLIEST ( write in exponential form) 26*26^8

Lisa [10]

Answer:

26 * 26^8 = 26^9

Step-by-step explanation:

Here, we want to write 26 * 26^8 in exponential form.

26* 26^8 is same as 26^1 * 26^8

According to the first law of indices, we are going to add the powers together;

Thus, this gives ; 26^(1 + 8) = 26^9

Hexagon DEFGHI is translated 8 units down and 3 units to the right. If the coordinates of the pre-image of point F are

Zina [86]

Answer:
(-6,-6)

Explanation:
The xy coordinate grid is shown in the attached image.
As we can see:
1- moving down the the y-axis means that we are moving towards the negative direction. This means that we will subtract the translated units from the original y-value to get the y-value of the image
We are given that the point was translated 8 units down and that the original y-coordinate was 2.
This means that:
y-coordinate of image = y-coordinate of original point - translated units
y-coordinate of image = 2 - 8
y-coordinate of image = -6

2- moving to the right of the x-axis means that we are moving towards the positive direction.This means that we will add the translated units to the original x-value to get the x-value of the image.
We are given that the point was translated 3 units to the right and that the original x-coordinate was -9.
This means that:
x-coordinate of image = x-coordinate of original point + translated units
x-coordinate of image = -9 + 3
x-coordinate of image = -6

Based on the above, the coordinates of the image are (-6,-6)

Hope this helps :)

Does anyone know how to sovle this

Umnica [9.8K]

The 2 interior angles add to the exterior angle
26+13=x
39=x

x=39°

because

remember, all angles add to 180
26+13+BCA=180
39+BCA=180
minus 39 both sides
BCA=141
look, we want x

BC is a striaign line which is 180
BCA+x=180
141+x=180
minus 141 from both sides
x=39°
