What is the value of 12x^-3 y-1 for x=-1 and y=5<br> A.-12/5<br> B.-180<br> C.-60<br> D.-5/12
Mkey [24]

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:

12x^{-3} y^{-1}

When x = -1, the expression becomes

12 * -1^{-3} y^{-1}

Evaluate the exponent

- 12 y^{-1}

When y = 5, the expression becomes

- 12 * 5^{-1}

Evaluate the exponent

- 12/5

Hence, the value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5

3. The teacher asked the class, "How many tenths are equivalent to 37.6?" Student 1 answered, "37 tenths." Student 2 answered, "
Ksivusya [100]

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.
