Since E is the midpoint, DE and EF are the same length.
Set the equation DE and EF equal to each other and solve for x.
2x + 4 = 3x - 1
x = 5
Then plug in 5 to find the length.
DE = 2(5) + 4 = 14
EF = 3(5) - 1 = 14
DF = DE + EF = 28
The question is biased towards a response of preferring to use weight-lifting machines because it uses the words "hard" to describe free weights and "easy" to describe the machines, and may persuade some people to choose the machine.
The sample is not biased because it doesn't choose specific women, it includes all women who visit the gym.
Answer:
= 3 R 43
= 3 43/268
847 divided by 268 equals
3 with a remainder of 43
Step-by-step explanation:
let the unknown be x
(-12) - x = 10
(-12) - 10 = x
-22 = x
if you wanna check,
(-12) - (-22) = 10
10 = 10
