2 expression are equivalent is B and C
First, draw the number line and assign the values of the real numbers that correspond (See the figure attached).
Now, let's represent the mixed numbers given in the problem.
Let's start with 8 2/5: This mixed number is located between 8 and 9. The numerator 2 of the fractional part, tells us how far from 8 it will be located and the denominator 5 indicates how many parts we must divide the space between these two numbers (8 and 9).
Now, to plot 2 3/4 on the number line, we have to follow the same proccedure: It is located between the numbers 2 and 3. The numerator 3 of the fractional part, tells us how far from 2 it will be located and the denominator 4 indicates how many parts we must divide the space between 2 and 3.
The sum of 70, 73, and 65 is 208. Adding a 72 to that equation makes the sum 280. The mean then becomes 70. The answer is 72.
Answer:
77 degrees
Step-by-step explanation:
Angles on a line add to 180. Since <KHE is on a line with <KHI, you would find the difference of the <KHI and 180 to find 77 degrees.
Answer:
4
Step-by-step explanation:
- 8+(-2) is 6
- 6-9 is -3
- -3 -(-7) is -3+7 which is 4
