Step-by-step explanation:
Since 74 is an even number, we can factor a 2 out of the exponent of your problem, like this:
i74=(i2)37.
But, i2=-1, so your problem becomes:
-137.
This means, multiply -1 by itself 37 times, to get -1
(Remember, -1 raised to an odd power is always -1, so -137=-1.)
The final answer is:
i74=-1
6 1/2 as an improper fraction is 13/2
Answer: 3,003 cubic meters

Answer:
x=7
Step-by-step explanation:
Answer:
x=60, y=30
Step-by-step explanation:
4x-7y=30
4x-5y=90
Subtract the equations
4x-7y=30-4x-5y=90
=2y=60
Solve 2y=60
Divide both sides by 2
2y/2=60/2
Simplify;
y=30
For 4x-7*30=30 for x
4x-7y*30=30
Multiply the numbers:7*30=210
4x-210=30
Add 210 to both sides
4x-210+210=30+210
Simplify;
4x=240
Divide both sides by 4
4x/4=240/4
Simplify
x=60
The solutions to the system of equations are:
x=60, y=30
