Step-by-step explanation:
Diameter = 2 times the radius or
D = 2r
Solve for r and substitute 10 for D
Line up the decimals on top of each other when doing the adding but still keep the numbers in the same order, it might look off and you should get 2.34.
Answer:
Dustin has 42 cards.
Mike has 54 cards.
Kevin has 39 cards
Step-by-step explanation:
subtract (Dustin + Mike) – (Dustin + Kevin) or 96 – 81.
Think of it like....
Dustin + Mike – Dustin – Kevin
Dustin – Dustin + Mike – Kevin
Mike – Kevin
Since 96 – 81 = 15, Mike – Kevin = 15
Add (Kevin + Mike) + (Mike – Kevin) or 93 + 15.
Think of it like...
Kevin + Mike + Mike – Kevin
Kevin – Kevin + Mike + Mike
Mike + Mike
Since 93 + 15 = 108, Mike + Mike = 108. If you divide, Mike had 54 cards. That means that you can find Kevin’s cards by using 93 – 54 or 39. You can then find Dustin’s cards by using 81 – 39 = 42.
Check:
Dustin’s cards + Kevin’s cards = 42 + 39 = 81
Dustin’s cards + Mike’s cards = 42 + 54 = 96
Mike’s cards + Kevin’s cards = 54 + 39 = 93
Answer:
x=30
Step-by-step explanation:
Since the measure of an exterior angle is equal to the sum of any two angles in a triangle, the equation would be 4x-18=2x+6+36. Solve this, and we get x=30.
Hope this helped!
