Answer:
x = 0
Step-by-step explanation:
First we set up our equation. From the picture we can see that:
11 + x + 1 = 2x + 12
Now we can gather our like terms:
x + 12 = 2x + 12
Lets subtract x from both sides to isolate the x on the left:
12 = x + 12
Next we subtract 12 from both sides
x = 0
Check the answer
11 + 0 + 1 = 2(0) + 12
12 = 0 + 12
12 = 12
216 = 6s^2
can be solved in the following manner.
216/6=s^2
36 = s^2
sqrt(36) = s
flip for better overview
s = 6
the length of each side is 6 inches. :)
Answer:
Male: Median: 64.5 and the mean is 70.6
Female: median: 83 and mean is: 79.93
Step-by-step explanation:
For median, you place all of the numbers from lowest to highest, and then find the number in the middle.
For Mean, add up all the numbers, then divide by the amount of numbers there.
For example.
30/5= 6
Because all 3 sides are given for both triangles you can use the SSS theorem
1) 55% is girls, then
100-55=45% is boys.
2) 45%=0.45 or 2) 400 ----100%
3)400*0.45= 180 boys x -----45% x=400*45/100=180 boys
Answer is 180 boys.
