Answer:
8.5 or 8 1/2
Step-by-step explanation:
Answer:
m^2/n
Step-by-step explanation:
The following laws of exponent are useful to this problem:

We are given the expression:

Use the first law of exponent above.

Make sure to recall the important necesscary fundamental math such as operation with negative numbers/integers, basic division, fraction, etc.
From the expression, apply the second law of exponent to n^-1.

Multiply m in.

Thus the answer is m^2/n.
Answer:
Step-by-step explanation:
It can be between 90° and 180°
Hi there!
To solve this problem using substitution, we need to set x equal to a value and substitute it into the other equation.
Since
x - 4y = 5,
x = 5 + 4y
3x - 7y = 10
3(5 + 4y) - 7y = 10
15 + 12y - 7y = 10
15 + 5y = 10
5y = -5
y = -1
Now that we know y is -1, we can substitute it back into the equation to find x:
y = -1
x - 4y = 5
x - 4(-1) = 5
x - (-4) = 5
x + 4 = 5
x = 1
So, your answers are x = 1 and y = -1.
Hope this helps!
