Let the number be x
1/2 x + 69 = 74
1/2 x= 74 - 69
1/2 x = 5
x = 2*5
x= 10

Answer:

10

Step-by-step explanation:

let the number be n then half the number is \frac{1}{2} n , so

\frac{1}{2} n + 69 = 74 ( subtract 69 from both sides )

\frac{1}{2} n = 5 ( multiply both sides by 2 to clear the fraction )

n = 10

Thus the number is 10

Sara makes and sells bracelets. She bought material for $28.50 and used it all to make 15 bracelets. Sara used the equation to d
Norma-Jean [14]

Answer:

Sara should sell each bracelet at <em>$8.50</em> to make a profit of $99.

Step-by-step explanation:

We are given the following:

Total cost = $28.50

Total bracelets to be made = 15

Total profit to be made = $99

Let x be the price at which Sara sells each bracelet to make a profit of $99.

\text{Total sales done = Number of bracelets sold }\times \text{ Sales price of each bracelet}\\

\Rightarrow 15 \times x    ...... (1)

Also,

\text{Total sales price = Total Cost}+ \text{Total Profit} \\

\Rightarrow \$28.50 + \$99 ....... (2)

Equating (1) and (2):

\Rightarrow  28.50 + 99 = 15x\\\Rightarrow x = \dfrac{127.5}{15}\\\Rightarrow x = $8.50

Sara should <em>sell each bracelet at $8.50</em> to make a profit of $99.

Explain when the median of a data set is a better measure of center than the mean.
shusha [124]
With data, you can have outliers. Outliers are values that do not follow what the range or majority of the data you collected so a value of 45, 42, 45, 48, 42, 44, 88, the mean will obviously be different because the 88 is going to change the whole data. But, if you put it from least to greatest, you can see what the majority of data is, (what the middle value is) to see what is in the middle range of what you have collect- the outliers don't affect what you have. Hence, 42, 42, 44, 45, 45, 88 (it's not much data) but it can show what the majority of data is. Hope this helps :> :)
