Answer:

46.5

Step-by-step explanation:

Of all straight angles have 180 degrees in them.

So, to find x we need to form this equation:

x + 65 + x - 22 = 180

2x + 43 = 180

2x = 180-43

2x = 137

68.5 degrees = x

68.5-22 = 46.5 degrees.

m<CBD = 46.5 degrees.

m<GBF = also 46.5 degrees because it is a vertical angle to <46.5 degrees.

If the diffrence in the side lenghts of two squares is 10,and the sum of the side lenghts is 18, what are the side lengths

konstantin123 [22]

Answer:

The side of first square =14 units

side of second square =4 units

Step-by-step explanation:

We have given two squares,

A square have all its four sides equal and at right angles.

Let the side of first square be 'a'

and the side of second square be 'b'

Given:

$a-b=10$ equation:1

$a+b=18$ equation:2

Solving equation:1

a=10+b equation:3

Putting 'a' in equation:2

$(10+b)+b=18\\\\2b=18-10\\\\2b=8\\\\b=4$

Putting 'b' in equation:3

$a=10+4\\\\a=14$

So, the side of first square is 14 units and

side of second square is 4 units

5(x-8)-(x+6)=18 solve for x

jeka94

5(x-8)-(x+6)=18
5x-40-x-6=18
4x-46=18
4x=18+46
4x=64
x=16

not sure if this is correct but i hope it helps!!!

Use the monthly payment formula to find the monthly payment for a $1,000, one year

wlad13 [49]

<h3>Answer: 89,58 $ </h3>

Step-by-step explanation:

The formula :

$\displaystyle \rm S=A\cdot \left (1+\frac{N}{100} \right )^{\big r}$

where r is years ; N is the percentage by which we increase the price ; A is the original price

In our case :

$\rm r=1 \ \ ; \ \ A=100 \ \ ; \ \ N=7,5\% \\\\ S=1000\cdot \bigg( 1+\dfrac{7,5}{100} \bigg)^1=1000\cdot 1,075=\boxed{1075\$}$

Then the monthly salary is equal to:

$\dfrac{1075}{12} \approx 89,58 \$$

Amy wants to carpet a room that is 12 feet by 8 feet. How many square yards of carpet will she need to complete the room?

adelina 88 [10]

Assuming that the room is rectangle and carpet is rectangle
area=legnth times width
legnth=longer than width
12 is longer than 8
12ft=legnth
8ft=width

now convert to yards
1 yard=3 feet
1 foot=1/3 yard
12 ft times 1/3=4yards
8 ft times 1/3=8/3yards
multiply

area=4 tiimes 8/3
area=32/3
area=10 and 2/3 square yards
