Answer:
3x-x+2=4
Step-by-step explanation:
Triangle AEB and triangle CED (second option)
1086
6+5(x-6)^3
6+5(8-2)^3
6+5(6)^3
6+5(216)
6+1080
=1086
Answer:
<em>x = 7.5 cm </em>
Step-by-step explanation:
ΔBCA ~ ΔECD ⇒ the corresponding sides are proportional.
=
AC = 4 + 6 = 10 cm
=
⇔ 10x = 6(x + 5) ⇒ <em>x = 7.5 cm</em>
Using the equation y=6x+12, where x is the number of hours and y is the total cost for the given value of x, you can plug in 42 for y and solve:
42=6x+12
42-12=6x
30/6=x
5=x
Thus, Amy can rent the bike for 5 hours.
