Answer:

10 5/6

Step-by-step explanation:

First we have to make 2 1/6 into an improper fraction. This can be rewritten as 13/6. Now, we can multiply 13 by 5 and get 65/6. If we re-convert this into a mixed number, 6 goes into 65 10 times with a remainder of 5, so the final answer is 10 5/6.

5 1/2 +1 3/10x=13 what does x equal

Advocard [28]

Answer:

$x=5\frac{10}{13}$

Explanation:

Given the equation

$5\frac{1}{2}+1\frac{3}{10}x=13$

Step 1: Change all the mixed fraction to improper fractions

$\implies\frac{11}{2}+\frac{13x}{10}=13$

Step 2: Find the lowest common multiple of the denominators (2 and 10)

The lowest common multiple = 10

Step 3: Multiply all through by 10.

$\begin{gathered} \implies\frac{11}{2}\times10+\frac{13x\times10}{10}=13\times10 \\ =55+13x=130 \end{gathered}$

Step 4: Apply the subtraction law of equality. (Subtract 55)

$\begin{gathered} 55-55+13x=130-55 \\ 13x=75 \end{gathered}$

Step 5: Apply the division law of equality. (Divide by 13)

$\begin{gathered} \frac{13x}{13}=\frac{75}{13} \\ x=5\frac{10}{13} \end{gathered}$

A study showed that the ratio of the number of people who get their news from social media to the number of people who their new

Kitty [74]

Answer: 240 people get the news from social media

Step-by-step explanation:

The ratio of the number of people who get their news from social media to the number of people who their news elsewhere is 3:7

Total ratio is the sum of the proportion of those that get their news from social media and those that got their news elsewhere.

It becomes 3+7 = 10

Total number of people in the town is 800

To determine the number of people that got their news from social media, we will divide the proportion of those that get their news from social media by the total ratio and multiply by the total number of people in the town. It becomes

3/10 × 800 = 240
