Answer:
addition
Step-by-step explanation:
Answer: 1. The additive inverse of a number is what you can add to that number for the sum to be zero. For real numbers, such as rational numbers, that means the additive inverse can be found by just flipping the sign of the number. The additive inverse property says if you add a number and its additive inverse, then the sum is zero.
For example, let's use the number 3. The additive inverse of 3 is -3, since 3 + (-3) = 0. This is also true the other way around. The additive inverse of -3 is 3.
When subtracting rational numbers, remember that subtracting is the same as adding a negative! That means 3 - 3 is the same as 3 + (-3) or -3 - (-3) is the same as -3 + 3. Both of these sums involve a number and its additive inverse and they add up to zero.
Answer:
The answer is 6.8 minutes per mile.
Step-by-step explanation:
We change: 7 3/4 = 31/4
and 52 7/10 = 527/10
Then 31/4 miles in 527/10 minutes, that means 1 mile will be in (527/10)/(31/4).
So we calculate: (527/10)/(31/4)= (527/10)*(4/31) = (527*4)/(10*31)= 17*4/10 = 17*2/5 = 34/5= 6.8
The answer is 6.8 minutes per mile.
Hope you understand.
Answer:
Step-by-step explanation:
We'll use rule of exponents to simplify expression.
Now, use the commutative property of multiplication.
In order to multiply power of the same base, we add their exponents.
→ Add exponents:
→ Multiply 3* -8
