Answer:
64 points can be earned by completing other kinds of problems.
Step-by-step explanation:
100 total points= 36 points from division problems+ x amount of points from other kinds of problems
100=36+x
100-36=64
64 points can be earned by completing other kinds of problems.
Answer:
$63
Step-by-step explanation:
First, we find the percentage that he saves:
9 is 3/5 of 15 which is 60%, 9 is 60% of 15 which means he save 60% of the money that he earns so,
60% of 105 = 63
This means he saved $65 from the money he earned.
Hope this helps!
The answer should have distributive property, but I'm not very sure yet.
We don't need the length AND width of the square. One number
will be enough for an answer, because all sides of a square have
the same length. Let's call that number ' M ' (for 'mystery number').
-- The area of the square is M² .
The question says that ...
-- The length of the rectangle is 2M .
-- The width of the rectangle is (M - 3) .
Therefore ...
-- The area of the rectangle is (2M)(M - 3) = 2M² - 6M .
The question also says that ...
-- The areas of the square and the rectangle are equal:
So 2M² - 6M = M²
Subtract M² from each side: M² - 6M = 0
Divide each side by M : M - 6 = 0
Add 6 to each side : M = 6 .
Check:
Assume ... Side of the square = 6
Then ...
Area of the square = 6² = 36 .
Length of the rectangle = (6 x 2) = 12
Width of the rectangle = (6 - 3) = 3
Area of the rectangle = (12 x 3) = 36
36 = 36 yay!
