7/4 you do this because, for example you can think of it like pizza and pizza slices. You have 1 pizza and 3/4 of a pizza, let’s say each slice is 1/4 of a pizza. How many slices do you have altogether? Seven. You can also think of 1 as 4/4, so the just add 3/4 + 4/4 (which is technically just 3+4) = 7/4
Answer:
3 47/50
Step-by-step explanation:
You have to make the denominators be the same, in this case, it would be easy to make it 100.
Then the expression would look like 3 24/100 + 70/100
The answer is 3 94/100
When simplified, itI is 3 47/50.
Hope this helps!!
Let me know if I'm wrong...
A) x= 5
b) x= 1
basically, 5x5x5=125 so that mean 5 to the power of 3 equals 125. This says x-2, so 5-2=3 which completes the equation of 5 to the power of 3. same with the second one.
