David > Chris
Chris < Annie
Annie = Sarah
Sarah < David
David is out since he is taller that Chris.
Anne is out since she is taller than Chris.
Sarah is out since Anne and Sarah are the same height.
Chris is the shortest, because he is shorter than Annie and Sarah, while Sarah and Annie are shorter than David, but Chris is shorter than Annie so Sarah applies too, Chris is shorter than Anne and Sarah.
Shortest ---> Tallest:
Chris, Anne, Sarah, David
1/2+1/4= 2/4+1/4= 3/4 or .75
Then,
3/4x=16
(3/4x)4/3=(16)4/3 *multiply by the reciprocal everytime you want to isolate x with a fraction\
x= 12
The answer for this one is $62.04
x^2 - 3x -28 ≥ 0
factor
(x-7) (x+4) ≥ 0
x=7 x=-4
we have three regions where the answers can lie
x<-4 between -4 and 7 and x>7
pick a point and see if it works
x=-10
(-10-7) (-10+4) ≥ 0
negative * negative is greater than 0 so this is a solution x< -4
x=0
(0-7) (+4) ≥ 0
negative * positive is less than 0 so this is not a solution
x=10
(10-7) (10+4) ≥ 0
positive * positive is greater than 0 so this is a solution x>7
We have two regions that work
x<-4 and x>7
Answer: The answer should be 39 yard line
Step-by-step explanation: If you start at the 50 and remove 11 yards you will have 39 yards left
