Answer:
z=-4
Step-by-step explanation:
Simplify 10 + 2z + 2z to 10 + 4z
Add 10 to both sides
Simplify 10 + 4z + 10 to 4z + 20
Subtract 4z from both sides
Simplify -z - 4z − z− 4z to -5z − 5z.
Divide both sides by -5 − 5
Simplify 20 / 5 to 4

d=vt will represent the Motion of Both persons
for Karen
d=59t
for Ricardo
d=65t
They're both 279miles away from each other
Meaning
Dk + Dr = 279
59t + 65t = 279
124t=279
t=279/124
t= 2.25hrs.
You can change to seconds if thats how the answer waa presented.
