(i honestly need this answered fast ! ) solve the proportion using cross products. round to the nearest hundredth if necessary. 12 miles/27 hours = 4 miles/ h hours a. 28 b. 12 c. 9 d. 18

he spend 5.1 minutes chatting with his friends

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5 1/10

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
