Answer:
-15
Step-by-step explanation:
We have the expression 3(2p - 5) - 6p and are asked to simplify.
Let's distribute, which is to multiply a number that is outside of a parenthesis bracket by the numbers inside the parenthesis.
3(2p - 5) - 6p
(3(2p) - 3(5)) - 6p
6p - 15 - 6p
Since you can only do changes to like terms and 15 and 6p are two different terms, we do 6p - 6p.
6p - 6p
0
Leaving us with -15.

Answer:
3 1/3 gallons
Step-by-step explanation:
There are 20 gallons and 6 families. We want to divide the 20 gallons equally amongst the 6 families. The key word here is "divide". We want to use division:
20 gallons ÷ 6 families = 20/6 gallon per family = 10/3 gallons per family
= 3
gallons per family
Thus, each family got 3 1/3 gallons.
Hope this helps!
Answer:
? =64.62306
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adjacent side / hypotenuse
cos ? = 3/7
Taking the inverse cos of each side
cos ^-1 ( cos ? ) = cos ^-1 (3/7)
? =64.62306
