At a water park there is a slide that you really want to ride. In order to get to the top of the 29 foot slide you must first cl
murzikaleks [220]

Answer: 20 feet

Step-by-step explanation:

This represents a right angled triangle with the length of the slide being the hypotenuse, the height of the ladder being the height of the triangle and the distance from the base of the ladder being the length.

Solve with Pythagoras rule:

c² = a² + b²

c = hypotenuse

a= length

b = height

29² = 21² + b²

841 = 441 + b²

b² = 841 - 441

b² = 400

b = √400

b = 20 feet

Samuel is solving the equation 3(x - 1) + 4 = 2 - (x + 3). Which equivalent equations might Samuel use? Select the TWO correct a
mote1985 [20]

A= 3, and 4. (c & d)

1. Solve the Equation: 3(x - 1) + 4 = 2 - (x + 3)\\, to get

------------------------------------------

1a. Use the distributive property to multiply 3 by x−1.

3x−3+4=2−(x+3)

1b. Add −3 and 4 to get 1.

3x+1=2−(x+3)

1c. To find the opposite of x+3, find the opposite of each term.

3x+1=2−x−3

1d. Subtract 3 from 2 to get −1.

3x+1=−1−x

1e. Add x to both sides.

3x+1+x=−1

1f. Combine 3x and x to get 4x.

4x+1=−1

1g. Subtract 1 from both sides.

4x=−1−1

1h. Subtract 1 from −1 to get −2.

4x=−2

1i. Divide both sides by 4.

x=4−2​

1j. Reduce the fraction 4−2​=−0.5 to lowest terms by extracting and canceling out 2.

x=−21​ or x = -21

-------------------------------------

Now that you know the answers, solve the others:

2. A= 1, so this is wrong. How I solved it is shown below:

-----------------------------------

1a. Add −3 and 4 to get 1.

3x+1=2−x+3

1b. Add 2 and 3 to get 5.

3x+1=5−x

1c. Add x to both sides.

3x+1+x=5

1d. Combine 3x and x to get 4x.

4x+1=5

1e. Subtract 1 from both sides.

4x=5−1

1f. Subtract 1 from 5 to get 4.

4x=4

1g.Divide both sides by 4.

x=44​

1h. Divide 4 by 4 to get 1.

x=1

----------------------------

3. A= .5, so it is Correct. Work below

-----------------------------

3a. Add x to both sides.

3x+3+x=5

3b. Combine 3x and x to get 4x.

4x+3=5

3c. Subtract 3 from both sides.

4x=5−3

3d. Subtract 3 from 5 to get 2.

4x=2

3e. Divide both sides by 4.

x=42​

3f. Reduce the fraction 42​=0.5 to lowest terms by extracting and canceling out 2.

x=21​ (A = 1/2 or .5)

-----------------------------

4. A= .5, so it is correct. Work below. Now we have our 2, so we don't need to do it again.

-------------------------------

4a. Add −1 and 4 to get 3.

3x+3=2−x+3

4b. Add 2 and 3 to get 5.

3x+3=5−x

4c. Add x to both sides.

3x+3+x=5

4d. Combine 3x and x to get 4x.

4x+3=5

4e. Subtract 3 from both sides.

4x=5−3

4f. Subtract 3 from 5 to get 2.

4x=2

4g. Divide both sides by 4.

x=\frac{2}{4}

4h. Reduce the fraction 42​=0.5 to lowest terms by extracting and canceling out 2.

x=\frac{1}{2}

Solve for x. 2x+5+6x-1=120​
svetlana [45]

Answer:

x=14.5

Step-by-step explanation:

2x+5+6x-1=120​

Combine like terms (combine all of the variables and then combine all of the constants)

8x+4=120

subtract 4 on both sides

8x=116

Divide 8

x=14.5

Hope this helps!
