Expressions are mathematical statements represented with the variables
The value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5
<h3>How to determine the value of the variable</h3>
The expression is given as:
When x = -1, the expression becomes
Evaluate the exponent
When y = 5, the expression becomes
Evaluate the exponent
- 12/5
Hence, the value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5

Using proportions, it is found that Student 2 is correct, as 37.6/0.1 = 376.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
One tenth is worth 0.1. How many tenths are there in 37.6? The division is given as follows:
37.6/0.1 = 376.
Hence student 2 is correct, as there are 376 tenths in 37.6.

Answer: 40
Step-by-step explanation:
angle 1 and 2 are alternative interior angle which means they are equal
-------------------------------
angle 1= angle 2
2x+20=3x+10
x=10
------------------------------
angle 1=2x+20
=2(10)+20
=20+20
=40
