Answer:
A
Step-by-step explanation:
10^4 = 10,000
10,000 × 2.18 = 21.800
Since there are no multiples other than 1 and -1 that could multiply in any way to equal 1, those are the only numbers you can really work with
it is a possibility that a, b, and c could equal 1 but then it would go wrong when comes time to subtract since all numbers are equal and cannot subtract largest from smallest.
a logical approach would be to try -1, -1, and 1 since -1 * -1 = 1 and then 1* 1 =1
we can make a= -1 , b= -1, and c= 1
(we need b to equal -1 so that we get an answer of -1 opposed to if we made a=-1 and c=-1, all outcomes would equal 1)
-1²=1
-1³=-1
1⁴= 1
since 1 is the largest possible outcome and -1 is the lowest possible outcome you should subtract the two
1-(-1) = 1+1 = 2
The answer should be D: 2
hoped this helped at all!
Answer: A
Step-by-step explanation:
19+13x+32
13x=32-19
13x=13
x=1
This is the concept of arithmetic:
Given that Carol ran a total 1 3/4 miles for 5 days last week, the total distance covered was:
Total distance=(distance per day)×(total number of days)
=1 3/4×5
=7/4×5
=35/4
=8 3/4 miles
Total distance ran this week is:
Total distance=(2 1/4×4)
=9/4x4
=9 miles
therefore we conclude that the distance covered this week was greater than the distance covered last week.
b] this distance was greater by:
difference=(distance covered this week)-(distance covered last week)
=9-35/4
=(36-35)/4
=1/4
the answer is 1/4 miles
