X=4 is your answer because 27 minus 7 is 20 and 20 divided by 5 is 4 have a good day
The answer is 1 USD = 1.0343 AUD
because the ratio is 1 USD:1.0343 AUD
fraction is
1.0343AUD/1USD
use to cancel out units
1.0343AUD/1USD times 80 USD=82.744 AUD
the answe ris the first one
You sometimes need to rewrite a factor because the lead number is not between 1 and 10 as it needs to be in scientific notation. For instance, if we had lead numbers of 2 and 5, as we do in the following problem.
2x10^3 * 5x10^9
Then we get the answer of 10x10^12. We need to adjust this by moving the decimal place and increasing the exponent by 1. The correct answer would be 1x10^13 instead.
Answer:
The sets E' and P' are not disjoint.
Step-by-step explanation:
Definition: Two sets are disjoint if their intersection is an empty set.
The sets are defined as follows.
We are to determine if the sets E' and P' are disjoint.
E' and P' are the complements of E and P respectively.
Therefore:
The intersection
Therefore, the sets E' and P' are not disjoint.
Remember that the angles of a triangle is 180 so:
(7x+8) + (5x+2) + (7x-1) = 180
7x+8+5x+2+7x-1=180
7x+5x+7x=180-8-2+1
19x=171
X= 171/19
X=9
Therefore x=9
