Answer:
Choice A: -36 + (-8)
Step-by-step explanation:
We want to find the equivalent expression to -36 - 8
The correct option is Choice A.
Choice A is -36 + (-8)
The reason is that the product of the signs + and - is -, i.e.
+ * - = -
Hence, + (-8) is the same thing as -8 and Choice A becomes -36 - 8
Answer:
Option (2)
Step-by-step explanation:
Given : y = 
If x = 7i
y = 
By simplifying denominator of the given rational expression,
y = 
y = 
y = 
y = 
[Since, i² = (-1)]
y = 
y = 
y = 
Therefore, Option (2) is the correct option.
Answer:
C. His answer is correct because 12 + 1 = 13 and 15 + 10 = 25.
Step-by-step explanation:
477
The value of the first 7 from the left is 70.
If you divide 70 by 10, you get the value of the second seven, 7.
Another way to know this is equivalent fractions:
1/10 = 7/10
10 X 7 = 70
1 X 7 = 7
