Sally plans to run 12 miles. She ran 5 1/8 miles and then stopped for a water break. How many miles does Sakky have left to run?
Answers
We can just subtract the fractions without converting any denominators. To do that, we can split the subtraction problem up as follows:
12 - 5 - 1/8
7 - 1/8
6 7/8
Sally still has 6 7/8 or 6.875 miles to run.

From the given information as Multiply 12 by the sum of 8 and t. The expression would be 12(8+t)
How to form mathematical expressions from the given description?
You can represent the unknown amounts by the use of variables.
Follow whatever the description is and convert it one by one mathematically.
For example, if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4.
If something is, for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert descriptions to mathematical expressions.

The algebraic expression which can be used to represent the length of the hypotenuse (h) of an isosceles right triangle is h=x√2.
How to write algebraic expression?
Algebraic expression are the expression which consist the variables, coefficients of variables and constants. The algebraic expression are used to represent the general problem in the mathematical way to solve them.
Steps to write down the simple algebraic expression-
- Identify all the factors of the expression.
- Assume a variable for the changing values.
- Put a coefficient for the variable, if there is any rate of change of variable.
- Use constant numbers for the fixed values.
An isosceles right triangle is a right triangle with congruent legs. The length of each leg is represented byx.
According to the Pythagoras theorem says that in a right angle triangle, the square of hypotenuse side is equal to the sum of square of other two legs of right angle triangle.
Let suppose the length of the hypotenuse is h. Thus, the algebraic expression can be used to represent the length of the hypotenuse is,
Hence, the algebraic expression which can be used to represent the length of the hypotenuse (h) of an isosceles right triangle is h=x√2.

a^2+b^2=c^2
if each leg (a and b) = x, then
x^2+x^2=c^2
2x^2=c^2
solving for c by taking the square root of both sides leaves
c=x×sqrt(2)
c must be positive since its a length, so no need for a +- I. this case
