Answer:
Elizabeth washes 99 windows each day.
Step-by-step explanation:
Given:
Total number of windows (N) = 2480
Marie washes windows = 4 times Elizabeth washes.
Elizabeth washes same number of windows for 5 days.
Let the number of windows washed by Elizabeth each day = 'x'.
Therefore, over the 5 days, the windows washed by Elizabeth =
Now, as per question:
Marie washes windows = 4 times Elizabeth washes.
So, number of windows washed by Marie =
Now, total number of windows = Windows washed by Marie + Windows washed by Elizabeth
So,
Therefore, Elizabeth washes 99 windows each day.
First look at all of the factors of 16:
(1, 16) (Cannot have only one group so this one does not work)
(2, 8) (this one is two equal groups of eight because 2x8 is 16)
(4, 4) (this one is four equal groups of four because 4x4 is 16)
(8, 2) (this one is eight equal groups of two because 8x2 is 16)
You can put it into two equal groups of 8 because 16/2 is 8
You can put it into four equal groups of 4 because 16/4 is 4
You can put it into eight equal groups of 2 because 16/8 is 2
I hope this helps!
Answer:
x = 2, x = - 2
Step-by-step explanation:
3x² - 12 = 0
3x² = 12
x²= 12/3
x²= 4
√x² = +/- √4
x = +/- 2
x = 2, x = -2
