Answer:

Step-by-step explanation:

First, in order to get rid of the parenthesis, you need to multiply 2.5 with whatever is in the parenthesis.

Multiply 2.5 on each side of the equation like this:

(12.75 x 2.5) (24.50 x 2.5) =188.75

Once you're finished, you should get 61.25 and 31.875x =188.75

Now in order to find 'x' you will need to subtract 61.25 to each side of the equation like this:

61.25 - 61.25 = 0

188.75 - 61.25 = 127.5

So now your equation should look like this:

31.875x = 127.5

You have to divide 31.875 by each side now.

Once you divide them, your final answer should be 4.

so x = 4.

I really hope this helps! ^^

Answer:

Step-by-step explanation:

because

Answer:

a. addition property of equality

Step-by-step explanation:

2x was added to both sides

Step-by-step explanation:

Step 2: -2x - 3 = x - 18

In order to go to Step 3, we must remove the -2x term from the left. In order to do this, we add 2x on both sides:

-2x - 3 + (2x) = x - 18 + (2x)

=> Step 3: -3 = 3x - 18.

Hence the answer is Addition Property of Equality. (A)

Answer:

B.76 square feet

Step-by-step explanation:

SA=B+L

Answer: B)  8.76 square feet

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

Explanation:

The base is a square with side length 0.6 ft, so the base area is 0.6*0.6 = 0.36 square feet.

Each lateral triangular panel has base 0.6 ft and height 7 ft. The area of one triangle is 0.5*base*height = 0.5*0.6*7 = 2.1 square feet

So four of these triangles combined give a lateral surface area of 4*2.1 = 8.4 square feet. Add this onto the base area to get 8.4+0.36 = 8.76 square feet of total surface area.

Answer:

Six-sided polygon that includes two isosceles right triangles, one with height and base of 25 feet,

Total area = triangle 1 area + triangle 2 area + rectangle area= 312.5 + 32 + 280 = 624.5

Triangle1 area = height × base2

Triangle1 area = 25 × 252/ = 312.5

The other height and base of 8 feet,

Triangle 2 area = height × base2

Triangle 2 area = 8 × 8/2= 32

And one rectangle measuring 35 feet by 8 feet

Rectangle area = height × base 

Rectangle area = 35 × 8 = 280

The area of the polygon is 624.50 ft².

The area of the polygon can be determined by adding the areas of the shapes in the polygon. The polygon is made up of two right triangles and a rectangle.

Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height

Area of a rectangle = length x width

Area of the rectangle

Area = 35 x 8 = 280 ft²

Area of the triangles

Area of the bigger triangle

Area = 1/2 x 25 x 25 = 312.50 ft²

Area of the smaller triangle

Area = 1/2 x 8 x 8 = 32 ft²

Area of the polygon = 32 ft² +  312.50 ft² +  280 ft² = 624.50 ft²

Answer:

2 8/11 = b

Step-by-step explanation:

2b + 8 - 5b + 3 = -13 + 8b - 5

combine like terms

11 - 3b = -18 + 8b

add 3b

11 = -18 + 11b

add 18

29 = 11b

divide by 11

2 8/11 = b
