You would start by adding the 18 to the 2 to give you 20. then you would subtract x from the 6x to give you 5x. then your equation should be 5x=20, then you divide 20 by 5 and that give you 4. So x would equal 4. x=4

Answer:

x=4

Step-by-step explanation:

Step 1: subtract 1x from both sides. You should get 2=5x-18.

Step 2: add 18 to both sides to get 5x=20.

Step 3: simplify. you should get x=4

Answer:

a) 6 1/4% of $3,875 is $242.18.

b) 16 2/3% of 96 lamps is 16 lamps.

c) 87 1/2% of 540.72 is 473.11

d) 33 1/3% of 750 boys is 252.52 boys

e) 66 1/2 % of 240 kg is 159.6 kg.

Step-by-step explanation:

x% of y is calculated as $\frac{x}{ 100} \times y$

Here calculating the given percentages:

a) 6 1/4% of $3,875

Now, 6 1/4 = 6+ 1/4 = 6.25

⇒6.25% of $3,875 = $\frac{6.25}{100} \times 3,875 = 242.18$

Hence, 6 1/4% of $3,875 is $242.18.

b) 16 2/3% of 96 lamps

Now, 16 2/3 = 16+ 2/3 = 16.67

⇒16.67% of 96 lamps = $\frac{16.67}{100} \times 96 = 16$

Hence, 16 2/3% of 96 lamps is 16 lamps.

c) 87 1/2% of 540.72

Now, 87 1/2 = 87+ 1/2 = 87.5

⇒87.5 % of 540.72 = $\frac{87.5}{100} \times 540.72 = 473.11$

Hence, 87 1/2% of 540.72 is 473.11

d) 33 1/3% of 750 boys

Now, 33 1/3 = 33+ 1/3 = 33.67

⇒33.67 % of 750 boys = $\frac{33.67}{100} \times 750 = 252.52$

Hence, 33 1/3% of 750 boys is 252.52 boys

e) 66 1/2 % of 240 kg

Now, 66 1/2 = 66+ 1/2 = 66.50

⇒66 1/2 % of 240 kg = $\frac{66.50}{100} \times 240 kg = 159.6$

Hence, 66 1/2 % of 240 kg is 159.6 kg.

A die is rolled and the results are 1, 2, 1, 4, 5, 6, 1, 3, 6, 6, 5, 2, 3.

ANTONII [103]

<h3>Answer: True</h3>

We have A = 2 copies of "2" showing up out of B = 13 rolls total

A/B = 2/13 = 0.1538 is the experimental probability of rolling a 2

Compare this with 1/6 which is the theoretical probability of rolling a 2 (since there is one side labeled "2" out of 6 sides total)

1/6 = 0.167 approximately

Comparing 0.1538 with 0.167 is fairly close

or you could argue that 2/13 is close to 2/12 = 1/6
