What is the answer to 2b + 8- 5b + 3 = -13 + 8b - 5

Answers

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

B= 2 7/11

EXPLANATION : 2b-5b = -3b & 8+3 =11 , that’s leaves you with 3b+11=-13+8b-5 . do it to the other side . -13-5=-18 . leaves you with the equation -3b+11=-18+8b !!
move the variable to the left side & the constant to the right . which leads you to -3b-8b=-18-11 !! combine like terms & that takes you to -11b=-29 !! Divide both sides by -11 which makes B = 29/11 which is equivalent to 2 7/11. or 2.63

A sign in a bakery gives these options:

15 cupcakes for $26
24 cupcakes for $42
40 cupcakes for $66
Find each unit price to the nearest cent, and show your reasoning.
Which option gives the lowest unit price?

Answers

Answer:

The lowest unit price would be last option

Step-by-step explanation:

We must divide the price by the amount of cupcakes we will be getting. Once we do that we'll get:

A. 1.77 cents

B. 1.75 cents

C. 1.65 cents

Hope this helped

Answer:

40 cupcakes for $66

Step-by-step explanation:

To find the unit price of something, dived the total amount by how may there are.

$26 divided by 15 cupcakes would be $1.7333333333, but if you round it up, it would be $1.74

$42 divided by 24 cupcakes would be $1.75

$66 divided by 40 cupcakes would be $1.65

A square pyramid is shown:

What is the surface area of the pyramid?

A. 2.46 square feet
B. 8.76 square feet
C. 5.16 square feet
D. 1.56 square feet

Answers

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.

On a large baking tray, 40 cookies can be baked together. To bake 40 cookies it takes 14 minutes, for baking 80 cookies it takes 28 minutes, for baking 100 cookies it takes 42 minutes. How much time will it take to bake 140 cookies?

A-49 B-56 C-57 D48

Answers

the answer is B (56) because it states that it takes 14 minutes to bake 40 cookies, and you already have 100 cookies so you would just add the time it took to bake 40 cookies which would be 42+14=56

2.5(12.75x + 24.50) = 188.75
1. Simplify both sides of the
equation
(remove parentheses
and/or combine like terms).
2. Use inverse operations and
properties of equality to
"undo" what is happening to
the variable. (use the
reverse order of operations
because we are undoing)
3. Check your answer by
substituting your answer
into the original equation.

Answers

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! ^^

X=4

Sue has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. Calculate the area of the polygon. Be sure to show all your work and explain your answer.

Answers

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 shapes in the polygon.

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 polygon

Area of the rectangle

Width = 8 feet Length = 35 feet

Area = 35 x 8 = 280 ft²

Area of the triangles

Area of the bigger triangle

Base = 33 ft - 8ft = 25 ftLength = 25 feet

Area = 1/2 x 25 x 25 = 312.50 ft²

Area of the smaller triangle

Base = 43 ft - 35ft = 8 ftLength = 8

Area = 1/2 x 8 x 8 = 32 ft²

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