Answer:
They stopped for lunch at 12:25 pm.
Step-by-step explanation:
They started skyiing at 10:30 am.
They skied for 1 hour and 55 minutes.
1 hour and 55 minutes is 5 minutes less than 2 hours.
2 hours after 10:30 am is 12:30 pm.
Taking the 5 minutes, we have 12:25 pm
x = 28
7(8 - x) = -5x
56 - 7x = -5x Distribute 7 to the parenthesis
56 = 2x Add -7x to both sides
28 = x Divide 2 to both sides

118.3 m²
Step 1. Calculate the <em>semiperimeter</em> (s).
s = (p + q + r)/2
s = (17 + 18+ 15)/2
s = 50/2
s = 25 m
===============
Step 2. Calculate the <em>area</em> (A).
Use <em>Heron’s formula</em>:
A = 118.3 m²
b
4 divided by 5 is equal to 0.8. This decimal can also be written as a fraction. 0.8 = eight tenths or 8/10 (4/5 in its reduced form).
