Which of the following is equal to 2?
A. 6 + 4 ÷ (2 + 1) × 3
B. (6 + 4 ÷ 2) – 1 × 3
C. 6 + (4 ÷ 2) + 1 × 3
D. (6 + 4) ÷ 2 – 1 × 3

Answers

I think the answer is B

Answer:

D

Step-by-step explanation:

Start with the values inside parentheses.

6 + 4 = 10

10 / 2 = 5

Then subtract 1*3.

5 - 3 = 2

*B is incorrect because according to order of operations, 4/2 should be calculated before adding 6.

Equations on both sides
3x + 5 = 2x -17

Solve it and show the work because i need to show the work

Answers

The answer would be for this problem is -22

Answer:

x = -22

Step-by-step explanation:

Subtract 5 from both sides

3x + 5 (-5) = 2x - 17 (-5)  

3x = 2x - 17

Subtract 2x from both sides

3x (-2x) = 2x (-2) -22  

x = -22

A certain television is advertised as a 54-inch TV (the diagonal length). If the width of the TV is 40 inches, how tall is the TV? Round to the nearest tenth of an inch.

Answers

Answer:

36.3

Step-by-step explanation:

I tried using the Pythagorean Theorem to measure the length (tallness) of the TV.

[tex]a^2 + b^2 = c^2[/tex]

[tex]a^2 + (40)^2 = (54)^2[/tex]

[tex]a^2 + 1600 = 2916[/tex]

[tex]a^2 = 2916-1600 = 1316[/tex]

[tex]a = \sqrt{1316}[/tex]

[tex]a = 36.27671429[/tex]

When this is rounded up to the nearest tenth, it would go up to 36.3.

So, the length (tallness) of the TV would be 36.3 inches.

Step-by-step explanation:

Step 1: Add the cost of the posters together

Shark: 1 = $2

Jellyfish: 1 = $6

2 + 6 = 8

Step 2: Divide the result by the total amount Mr. Benson spent

64 ÷ 8

[tex]= \frac{64}{8}[/tex]

3. A class rolled number cubes. Their results are shown in the table. What is the experimental probability of rolling the number 1? Round your answer to the nearest tenth.

17.2%
16.4%
15.7%
17.5%

Answers

Answer:

15.7%

Step-by-step explanation:

Experimental probability is the probability of something that is determined by doing an experiment.

To find the probability, divide the number of rolling a one and add all the occurrences of every other result.

So,

42 / (42 + 44 + 45 + 44 + 47 + 46) =

42 / 268 =

0.156716 =

15.6716

Rounded to the nearest tenth, the probability of rolling a one would be 15.7%.

The answer is 276.32 square yards.

Step-by-step explanation:

To solve for the surface area of a cylinder, use the surface area of a cylinder formula, which is SA= 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex][tex]r^{2}[/tex]. However, instead of using ([tex]\pi[/tex]), 3.14 will be used.

Next, plug in the information from the question into the formula. The formula will look like SA= 2(3.14)(4)(7) + 2(3.14)([tex]4^{2}[/tex]). Then, solve the equation, and the final answer will be 276.32 square yards.
