Answer:

x = 6

Step-by-step explanation:

(x + 2) + (2x + 3) = 23

Combine like terms

3x +5 = 23

Subtract 5 from each side

3x+5-5 = 23-5

3x = 18

Divide each side by 3

3x/3 = 18/3

x = 6

Answer:

x = 6

Step-by-step explanation:

1. Remove parentheses where unneeded. x + 2 + 2x + 3 = 23

2. Add constants. x + 5 + 2x = 23

3. Combine like terms. 3x + 5 = 23

4. Subtract "5" from the constants on both sides of the equation. 3x = 18

5. Divide both sides by 3. 3x/3 = 18/3

6. Simplify. x = 6

Answer:

x=6

Step-by-step explanation:

Step 1: Subtract 4x from both sides.

5x−3−4x=4x+3−4x

x−3=3

Step 2: Add 3 to both sides.

x−3+3=3+3

x=6

Answer:

B.

Step-by-step explanation:

5x-3+3=4x+3+3

5x=4x+6

5x-4x=4x+6-4x

x=6

The 6 faces of a cube have equal are.

Each face has are of 5*5=25 because they are all squares.

Now we just multiply by 6

25*6=150 centimeters cubed.

Done!

Step-by-step explanation:

step 1. a cube had 6 sides

step 2. each side is a square

step 3. the area of each side is 5x5 = 25cm^2

step 4. the surface area of the cube is 25x6 = 150cm^2.

Step-by-step explanation:

the vertical LIne test. The lines intercept, so it is not a function.

Answer:

104

Explanation:

1. Split the figure by the line the larger portion creates.

2. Calculate the area of the left-hand side... 7 · 8 = 56cm squared.

3. You know that the total length of the figure is 15cm. You've already "used" 7cm of that. So... 15 - 7 = 8.

4. Now, we simply do 6 · 8 = 48. Almost there!

5. Finally, add the values of the left side and the right side (48 + 56 = 104)

6. YOUR ANSWER IS 104 cm squared.

Answer:

Step-by-step explanation:

Answer:

3 pieces

Step-by-step explanation:

Given: Figure

To find: Number of 8.5 in. ×  11 in. pieces used to cover the floors  of a room and a hallway in  her dollhouse

Solution:

In the given figure, AC = 22 in.

AB + BC = 22 in.

AB + EF = 22 (As BC = EF being opposite sides of rectangle)

AB + 10 = 22

AB = 22 - 10 = 12 in.

Area of rectangle ABGH = AB × AH = 12 × 5 = 60 square inches

(area of rectangle = length × breadth )

CE = CD + DE = AH + GF (As CD = AH and DE = GF)

CE = 5 + 15 = 20 inches

Area of rectangle BCEF = BC × CE = 10 × 20 = 200 square inches

(BC = EF = 10 in.)

Total area of the figure = Area of rectangle ABGH + Area of rectangle BCEF = 60 + 200 = 260 square inches

Area of pieces of felt = 8.5 × 11

So,

Number of pieces required = Total area of the figure / Area of pieces of felt  =   3 pieces

Answer:

the answer is below :)

Step-by-step explanation:

BigBytes will be 100 +10x = y ($100 flat fee plus 10 times the number of gigabytes equals total cost).

GoGig will be 120 + 5x = y.  ($120 flat fee plus 5 times the number of gigabytes equals total cost).

Now set them equal to each other and solve for x to find where the gigabytes are the same.

100 + 10x = 120 + 5x

Subtract 100 from both sides:  10x = 20 + 5x

Subtract 5x from both sides:  5x = 20.

Divide both sides by 5:  x = 4.  4 gigabytes is the answer.

The total amount you will pay for phone service is 4 gigabytes.

An equation is an expression that shows the relationship between two or more numbers and variables.

BigBytes will be 100 +10x = y

Therefore , We have $100 flat fee plus 10 times the number of gigabytes equals total cost).

GoGig will be 120 + 5x = y.  

We have $120 flat fee plus 5 times the number of gigabytes equals total cost).

Now set them equal to each other and solve for x;

100 + 10x = 120 + 5x

Now Subtract 100 from both sides:  

10x = 20 + 5x

Then Subtract 5x from both sides:

5x = 20.

Now Divide both sides by 5:  

x = 4.  

Hence, the total amount you will pay for phone service is 4 gigabytes.

Formula of area

AREA = LENGTH (multiply) BREATH

Answer:

The area of a triangle can be calculated with the formula: 1/2(bh), where b is the base length, and h is the height.

In this case, 4 is the base, and 7 is the height.

So we have: Area = 1/2(4)(7)

Simplifying: Area = 2(7), Area = 14.

The area of the triangle is 14 meters squared.
