Example to help you out!
May rides her bike the same distance that leah walks. may rides her bike 10 km/h faster than leah walks. if it takes may 1 h and leah 3 h to travel that distance, how fast does each travel?
----------------------------------------
May DATA:
time = 1 hr. ; rate = x+10 mph ; distance = rt = (x+10)*1 mi
--------------------
Leah DATA:
time = 3 hr. ; rate = x mph ; distance = rt = 3x mi
-----------------------
Equation:
distance = distance
x+10 = 3x
2x = 10
x = 5 mph (Leah's rate)
x+10 = 15 mph (May's rate)
Step-by-step explanation:
Area of a triangle = [B(h)] : 2 = (ab) : 2 = [90ft x 120ft] : 2 = 5400ft squared.
Answer:
x = -12 x = -5
Step-by-step explanation:
-7x-60=x^2+10x
Add 7x to each side
-60=x^2+10x+7x
-60=x^2+17x
Add 60 to each side
0 = x^2+17x+60
Factor
What 2 numbers multiply to 60 and add to 17
12*5 = 60
12+5 = 17
0 = (x+12) (x+5)
Using the zero product property
x+12 = 0 x+5 =0
x = -12 x = -5
