No they do not have the same number of zeroes
Although the 2 products do seem like they might have the same number of zeroes, 40 x 500 and 40 x 600
both have 3 zeroes before multiplying
if we take the first 2 digits of the 2 numbers being multiplied to get an idea of the answer
if we take 40 x 500 - 4 x 5 = 20
then theres an extra zero added
but if we take 40 x 600 - 4 x 6 = 24
no extra zeroes added to this
so if we finally look at the answers
40 x 500 = 20 000
40 x 600 = 24 000
20000 has 4 zeroes and 24000 has 3 zeroes
so the answer is no they dont have the same number of zeroes
If you would like to solve 2x + 5y = - 13 and 3x - 4y = -8, you can do this using the following steps:
<span>2x + 5y = -13 /*4
3x - 4y = -8 /*5
</span>_________________
8x + 20y = -52
15x - 20y = -40
_________________
8x + 15x + 20y - 20y = -52 - 40
23x = -92 /23
x = -92 / 23
x = -4
<span>2x + 5y = -13
</span>2 * (-4) + 5y = -13
-8 + 5y = -13
5y = -13 + 8
5y = -5
y = -1
(x, y) = (-4, -1)
The correct result would be D.) <span>(-4, -1).</span>
Answer: 9
Step-by-step explanation:
The factors of 27 are: 1, 3, 9, 27
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54
Then the greatest common factor is 9.
Hope this helped ! :)
