The phrase "the sum of twice a number and 5 is 17" can be translated into an equation. Let the unknown number be represented by ( x ). The equation can be written as ( 2x + 5 = 17 ).
"the sum of 2" and "twice" "a number" "is" "36"2+2x=36 â–
To write twice the sum of a number and 600, you first express the number as a variable, such as ( x ). The sum of the number and 600 can be written as ( x + 600 ). Therefore, twice this sum is represented as ( 2(x + 600) ).
It is 2*(x+4)
2 + 2x = 36
2n + 15 = 37

You want to create an equation for this. The equation should look like this: x^2 - 2x + 4 = 0 Use the quadratic equation to solve it.
If the number is n, then twice the number is 2n and the sum of the two is n + 2n = 3n.
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
This is an algebraic expression. It can be written as 3(2x + 4)
The expression "twice the quotient of 50 and the sum of a number y and 8" can be written mathematically as ( 2 \times \frac{50}{y + 8} ). This represents taking the sum of ( y ) and 8, finding the quotient of 50 divided by that sum, and then multiplying the result by 2.
Your equation would be 5(x + 4). In this case it's easiest to work backwards, starting with the "sum of a number and four" part of the problem. This is simply written as x + 4, since we don't know what "a number" is referring to and have to call it x. Then we just need to multiply that answer by 5, so we'd write the equation as 5 * (x + 4) or 5(x + 4). Make sure you have the parentheses, because if not it changes the answer entirely.
