Paige was assigned 40 math problems.
An expression is a combination of numbers, variables, and operators that represents a mathematical quantity or relationship. Expressions do not contain an equals sign (=) and are not true or false statements. Instead, expressions are evaluated to produce a value or another expression.
Let's call the total number of math problems Paige was assigned "x".
Paige solved the first 32 problems, so she still had to solve x - 32 problems after dinner.
We know that she finished the last 20% of the assignment after dinner, which means she solved 80% of the problems before dinner.
80% of x can be written as 0.8x.
So, the equation we can set up is:
x - 32 = 0.2x
Solving for x, we get:
0.8x = 32
x = 40
Therefore, Paige was assigned 40 math problems.

10(n+14)=N
10(n+14)=14
Answer:
10(n+14)=9N
Step-by-step explanation:
Lets let N represent the number that which we do not know.
We know that 10 is multiplied by the sum of N and 14, so lets write that down:
10(n+14)
We also know that what we just found is equal to 9 multiplied by the same number:
10(n+14)=9N
The variable stays the same throughout the entirety of the equation.
ANSWER:
The interest earned on a principle of $671.37 at an interest rate of 4% for four years is $ 107.42.
SOLUTION:
Given, p = $671.37, R = 4%, t = 4.
We need to find the simple interest for the above given values of amount, rate and years.
We know that
where, p = principal amount ; r = rate of interest ; t = number of years
By substituting the values we get,
Simple interest is $ 107.42 approximately.
Hence, the interest earned on a principle of $671.37 at an interest rate of 4% for four years is $ 107.42.
Answer:
$26.8548
Step-by-step explanation:
The number 7/10 is a rational number.
A rational number is any number that can be expressed as the ratio of two integers, where the denominator is not zero.
In the case of 7/10, both the numerator (7) and the denominator (10) are integers.
Since 7/10 can be written as the fraction of two integers, it falls under the category of rational numbers.
Rational numbers can be expressed as fractions or terminating or repeating decimals.
In this case, 7/10 can be written as the fraction 7/10 or as the decimal 0.7, which is a terminating decimal.
