Answer: 9
Step-by-step explanation:
12 + 8 + 7 + 12 + 6 = 45
There are 5 numbers
45 / 5 = 9
Answer:
mean = 9
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex] , then
mean = [tex]\frac{12+8+7+12+6}{5}[/tex] = [tex]\frac{45}{5}[/tex] = 9

Zander read 13 3/4pages in 1/4 of an hour. Sydney read 43 1/3 pages in 2/3 of an hour. At these rates, would Zander or Sydney read more pages in 1 hour?
Answer:
At these rates Sydney read 10 pages per hour more than Zander.
Step-by-step explanation:
Zander read [tex]13\frac{3}{4}[/tex] pages in [tex]\frac{1}{4}[/tex] of an hour.
Therefore, pages read by Zander in 1 hour = [tex]\frac{\text{Total pages read}}{\text{Total time taken}}[/tex]
= [tex]\frac{13\frac{3}{4}}{\frac{1}{4}}[/tex]
= [tex]\frac{55}{4}\times \frac{4}{1}[/tex]
= 55 pages per hour
Sydney read [tex]43\frac{1}{3}[/tex] pages in [tex]\frac{2}{3}[/tex] of an hours.
Pages read by Sydney in 1 hour = [tex]\frac{43\frac{1}{3}}{\frac{2}{3} }[/tex]
= [tex]\frac{130}{3}\times \frac{3}{2}[/tex]
= 65 pages per hour
Therefore, number of pages read more by Sydney as compared to Zander,
= 65 - 55
= 10 pages per hour
At these rates Sydney read 10 pages per hour more than Zander.

Complete the equation of the line through (-6, 5) and (-3, -3)
Answer:
y = -8/3x - 11
Step-by-step explanation:
(-6, 5) and (-3, -3)
Slope:
m=(y2-y1)/(x2-x1)
m=(-3-5)/(-3+6)
m=(-8)/3
m= -8/3
Slope-intercept:
y - y1 = m(x - x1)
y - 5 = -8/3(x + 6)
y - 5 = -8/3x - 16
y = -8/3x - 11
I need the answer for this. Please help

Bailey made risotto using a recipe that called for 223 cups of liquid. Bailey added 23 cup of liquid to the risotto every 10 minutes. Drag and drop to complete the equation to find how many times Bailey added 23 cup of liquid.
Answer:
4 times
Step-by-step explanation:
Given that :
Cups of liquid required = 2 2/3
Fraction of liquid cup added per 10 minutes = 2/3
The number of times 2/3 cups of liquid is added :
Total cups of liquid required / amount of liquid added at a time
2 2/3 ÷ 2/3
8/3 ÷ 2/3
8/3 * 3/2
24 / 6
= 4 times

Figure ABCD is a rectangle. In rectangles, opposite sides are equal. In the figure, BC and AD are opposite of each other, therefore their side lengths are equal. The side lengths are given: BC=9x-6, and AD=3x+12. Write this as an equation:
9x-6=3x+129x-3x-6=3x-3x+12 (Subtract 3x from each side of the equation)6x-6=12 6x-6+6=12+6 (Add 6 to each side of the equation)6x=18x=3 (Divide each side by 6)please let me know if this is wrong, hope it helps :)

Answer: 1430 girls
Step-by-step explanation:
In order to solve this we must take it step by step. So first things first. There are 12,481 people at this concert. If 8906 are adults we need to subtract to find out how many children there are. 12481-8906=3575. There are 3,575 children at this concert. Now if 3/5 of the children are boys then the other missing 2/5 must be the girls. There are a couple of ways to solve this but im going to go the direct route. multiply 3/5 by 3,575 to get 2,145 boys. Now if 2,145 out of 3,575 are boys then 3575-2145= 1430 girls
Let's sum up what we learned
1. 12,481 people are at a concert
2. 8906 adults are at this concert
3. 3,575 are children
4. 2145 are boys
5. Which means there are 1430 girls

Answer:
x₂ = - 3
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to [tex]\frac{5}{6}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (9, 9) and (x₂, y₂ ) = (x₂, - 1)
m = [tex]\frac{-1-9}{x_{2}-9 }[/tex] , that is
[tex]\frac{-10}{x_{2}-9 }[/tex] = [tex]\frac{5}{6}[/tex] ( cross- multiply )
5(x₂ - 9) = - 60 ( divide both sides by 5 )
x₂ - 9 = - 12 ( add 9 to both sides )
x₂ = - 3
