Answer:
3.4 quarts of white paint
Step-by-step explanation:
if you divide 8.5 quarts by the five parts you get 1.7 which you then multiply by 2 parts to find the amount of white paint
Answer: 
Step-by-step explanation:
If we model the clock as a circumference, we will be able to see that a complete turn (the whole circumference) represents
, hence:

Now we have to find the equivalence between
and
and degrees. So, in order to do this, we can make a Rule of Three:
For
:



For
:



Adding both angles:
You will need to use FOIL for this, or distribute.
So you will multiply -7y and 5y, then -7y and 3
Multiply 2 and 5y, then 2 and 3
You will get: -35y²-21+10y+6
Combine like terms:
-35y²+10y-15
There you go!
Answer:
1
= -----------
6(x + 7)
Step-by-step explanation:
3x - 21 x^2 - 49
----------- ÷ -------------
18x - 18 x - 1
3x - 21 x - 1
----------- × -------------
18x - 18 x^2 - 49
Factor the top left:
3x - 21 = 3(x - 7)
Factor the bottom left:
18x - 18 = 18(x - 1)
Factor the new bottom right:
x^2 - 49 = (x + 7)(x - 7)
Multiply and simplify the faction:
3(x - 7) x - 1
----------- × -----------------
18(x - 1) (x + 7)(x - 7)
1
= -------------
6(x + 7)
The answer is -1. You multiply the 1/4 with the 5x and equal it to 3 multiplied by 5 and have gotten 15x, then multiply the 3 with the 2, as apart of the parentheses. Lasty you just leave the -9 on the side and solve the equation.
