Answer:
PR=71
Step-by-step explanation:
visualize:
P Q R
O-------------O-------------O
13 58
so if PQ + QR = PR, than 13+58=PR
13+58=71
PR=71
The solution to the problem is x < 31/55
Answer:
√19 or 4.36 to the nearest hundredth
Step-by-step explanation:
10^2 = 9^2 + x^2
x^2 = 10^2 - 9^2
x^2 = (10-9)(10+9) = 19
x = √19.
So first you would multiply $6.50 by 4.5 and you get 29.25, so that represents how much she would make in one day! Then multiply 5 days a week by 6 weeks and you get 30 then multiply $29.25 by 30 to get the total!
