Answer:
1) Since AP/AB=PQ/BC, 6x/(3x+5)=x/1. Cross multiply the denominator and you will get 6x=(3x+5)*x. Simplifying it more and you are left with 3x^2-x=0
2) 3x^2-x=0. x(3x-1)=0. x=0 or x=1/3 but x=0 can't be a solution since it would make the figure absurd. x=1/3 cm
3) According to the figure PB=AB-AP=3x+5-6x=-3x+5.
PB=-3*(1/3)+5=4 cm
Answer:
50 minutes = B
Step-by-step explanation:
Andre can run 5 miles in 40 minutes
for 1 miles = 40/5 = 8 minutes
1 mile = 1.61 kilometres
x = 10 kilometres
x= (10x1)/1.61= 10/1.61 = 6.21miles
- for 1 miles = 40/5 = 8 minutes
- 6.21 miles = 8 x 6.21 = 49.689 minutes ≈ 50 minutes = B
