1 hour divided by 4 is 15
hope that helped
Well 4^m*4^n can be added so lets say you have 4^4*4^6 that would just be adding the exponets to get 4^10. but (4^m)^n that is multiplying the exponet of 4 to n so (4^6)^4 would be 4^24.
For the answer to the question above,
2x + 4y = –7 (1)
y = -1/2x + 5 (2)
Putting (2) into (1), we have:
-2x + 4(-1/2x + 5) = -7
-2x - 2x + 5 = -7
-4x = -7 - 5 = -12
x = -12/-4 = 3
y = -1/2(3) + 5 = -3/2 + 5 = 7/2
Therefore there is only one solution
I hoipe my answer helped you. Feel free to ask more questions. Have a nice day!
Answer:
Step-by-step explanation:
1. Solve what is in parenthesis first. (230-180+10) = 60
2. Multiply 60 and 32 = 1920
3. Add 3
Answer: 1923
Are you supposed to do all the ones in the quotations?
