Answer:
AD=7.5
Step-by-step explanation:
If AB=15 and D is the midpoint that means AD=DB which is half of AD,
AD=AB/2
AD=15/2
therefore AD=7.5
Here is a `5`-by-`8` grid.
Create a design so that there are `3` times as many unshaded squares as there are shaded squares.
x = number of shaded squares
3x = number of unshaded squares
This is because there are 3 times as many unshaded squares compared to shaded
unshaded = 3*(shaded)
Since there are 5*8 = 40 squares overall, this means,
shaded+unshaded = 40
x+3x = 40
4x = 40
x = 40/4
x = 10
There are 10 shaded squares and 3x = 3*10 = 30 unshaded squares.
So you'll shade in 10 squares in any fashion you prefer.

Answer:
x = -4
Step-by-step explanation:
-2(3x - 4) - x - 3 = 33
~Simplify
-6x + 8 - x - 3
-7x + 5 = 33
~Subtract 3 to both sides
-7x = 28
~Divide -7 to both sides
x = -4
Best of Luck!
Answer:
x = -4
Step-by-step explanation:
-2(3x - 4) - x - 3 = 33
solve the brackets first
-6x + 8 -x -3 = 33
-6x - x + 8 - 3 = 33
-7x + 5 = 33
-7x = 33-5
-7x = 28
x = 28/ -7
x = -4

Karl drove for 4 hours. For part of the trip he drove at 50 miles per hour. For the rest of the trip he drove at 100 miles per hour.
All together he drove 250 miles.
Solve this equation for h to find out how many hours he drove at 50 miles per hour.
250 = 50h + 100(4 - h)
Answer:
3 hours
Step-by-step explanation:
250 = 50h + 100(4 - h)
250 = 50h + 400 - 100h
250 = -50h + 400
-150 = -50h
h = 3

Answer:
50° and 130°Step-by-step explanation:
∠1 with 53° arc measure is vertical pair with 47° arc:
m∠1 = 1/2(53° + 47°) = 1/2(100°) = 50°∠1 and ∠2 are forming a straight line:
m∠2 = 180° - 50° = 130°53° and 47° angled arcs are vertical pairs
m<1=1/2(47+53)=50°<1 and <2 are linear pair
m<2=180-50=130°
Ray's birthday is 8 more than four times the number of days away from today than Jane's birthday. If Ray's birthday is 24 days from today, how many days untill Jane's birthday?
Answer:
4 days
Step-by-step explanation:
Since it is 8 more than 4 times, take 24 because that is how many days away rays birthday is and subtract 8. So now we have 24-8 which is 16. Now divide 16 by 4 to get 4 which is how many days away janes birthday is. So the answer is 4 days.

f(x)=2x^2-5;find when f(x)=-7
Answer:
x=i or no solution exists depending on the user's grade
Step-by-step explanation:
f(x) = 2x^2-5
-7 = 2x^2-5
-2 = 2x^2, x^2=-1, x=i
Answer:
±i = x
Step-by-step explanation:
f(x)=2x^2-5;
f(x)=-7
-7 = 2x^2 -5
Add 5 to each side
-7+5 = 2x^2 -5+5
-2 =2x^2
Divide by 2
-2/2 =2x^2 /2
-1 = x^2
Take the square root of each side
sqrt(-1) = sqrt(x^2)

use the following list to find the average or mean, the median, the mode, and the range 10, 15, 5, 8, 6, 6, 2
Answer:
Mean - 7.43
Median - 6
Mode - 8
Range - 13
Step-by-step explanation:
To find the mean/average, add up all the numbers and divide the sum by the # of data points. (ex. you have 7 numbers, so you divide the sum of the numbers by 7.)
The median of a set of data is the middle number of ascending numbers in the data. If there was an even number of data points you would have to add the 2 middle numbers and divide by 2.
The mode is the number that appears most frequently in the data set.
To find the range, just subtract the lowest number in the data set from the greatest number.
Answer:
mean= 7.4, median = 6, mode =6, range = 13
Step-by-step explanation:
mean = 10 + 15 + 5 + 8 + 6 + 6 + 2 ÷ 7
= 52 ÷ 7
= 7.4
median= 2, 5, 6, 6, 8, 10 , 15
6
median is the middle number from ascending order
mode = 6
mode is the number that occurs the most
range = 15 - 2
13
range is the different between the largest and smallest number

evaluate the expression when y= -2 and z = -5
2z/y
Answer:
5 is the answer
Step-by-step explanation:
[tex] \frac{2 z}{y } \\ = \frac{2 \times ( - 5)}{ - 2} \\ = \frac{ - 10}{ - 2} \\ = 5 \: ans.[/tex]
when \(y = -2\) and \(z = -5\), the value of the expression \(2z/y\) is \(5\).
How to evaluate the expression when y= -2 and z = -5 2z/yTo evaluate the expression \(2z/y\) when \(y = -2\) and \(z = -5\), follow these steps:
1. Substitute the values of \(y\) and \(z\) into the expression:
\(2z/y = 2(-5) / (-2)\)
2. Perform the calculations:
\(2z/y = -10 / (-2) = 5\)
So, when \(y = -2\) and \(z = -5\), the value of the expression \(2z/y\) is \(5\).
