Not A.(17 is a common factor)
B. only common factor is 1
not C (7 is a common factor)
D. only common factor is 1
Both B and D are relatively prime.
Answer:
1/5
1. 1/56
2. 1/6
3. 1/65
4. 1/7
5. 1/75
1/8
Step-by-step explanation:
The fractions I gave (1/56, 1/6, 1/65, 1/7, 1/75) are all in between 1/5 and 1/8.
A way to think about this is to add a zero to a denominator of 1/5 and 1/8 and turn them into whole numbers:
1/5 --> 1/50 --> 50
1/8 --> 1/80 --> 80
Then find number between them:
55, 60, 65, 70, 75
Then, turn them into a fraction with a 1 as the numerator and the number as denominators:
1/55, 1/60, 1/65, 1/70, 1/75
This is the process. These numbers are all in between 1/5 and 1/8.
I hope this helps you!
(P.S., I don't think this works with negative numbers, though)
Evaluate the expression using x = –1 and y=3.
1. Substitute the values for the variables.
we plug in -1 for x and 3 for y
2. Identify grouping symbols, beginning with the innermost symbols.
We take exponent and then we multiply
3. Determine and apply the rules of exponents to simplify
(-1)^4 = -1 * -1 * -1 * -1 = 1
(3)^3 = 3*3*3= 27
4. Evaluate.
162
The value of the expression is 162
