FALSE! Any 3 angles of any triangle add up to 180 degrees. An equilateral triangle's angles should each be 60 degrees.
Answer:
Crew: 32
Marty: 48
Blakely: 24
Step-by-step explanation:
I mainly just used guess and check. Crew is 32 years old. So, let's find Marty's age.
32 × 1. 5 = 48
Marty is 48. Now, let's find Blakely's age.
32 × 0.75 = 24
Add all the ages together.
32 + 48 + 24 = 104
Hope that helps.
R + s + t
Plug in the values.
r = 26
s = -12
t = -8
r + s + t
26 + (-12) + (-8)
26 - 12 - 8
14 - 8
6
Remember these rules:
a + (+b) = a + b
a + (-b) = a - b
a - (+b) = a - b
a - (-b) = a + b
