I need this done asap for a quiz

(Only instructions)

Step-by-step explanation:

Just turn the different shapes into different variables to make it easier. The top one would turn into 3x = 30 as an example. Then use systems of equations to find out the variables.

ryan had a head start of 10 meters.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
