Answer:
x=30
Step-by-step explanation:
x+2x+3x=180
6x=180
x=180/6=30
Answer:
D)
Step-by-step explanation:
To start, we know that the initial boiling point is 212 degrees F. For every 1 added to E, the boiling point decreases by 2. So, we havethe equation 212 - 2E or -2E + 212 = b or D).
The algebraic expression which represents the square of the difference of s and 6 is (s - 6)²
Step-by-step explanation:
Let us represent some words by mathematics expressions
- Square a number ⇒ x²
- Square the sum of two numbers ⇒ (x + y)²
- Sum of the squares of two numbers ⇒ x² + y²
- Square of difference of two numbers (x - y)²
- The difference of square two numbers x² - y²
∵ The expression is the square of the difference of s and 6
- That means find the difference between s and 6 at first,
then square the difference
∵ The difference of s and 6 = s - 6
- Square this difference means but the difference in a bracket
and then square the bracket
∴ The square of the difference = (s - 6)²
The algebraic expression which represents the square of the difference of s and 6 is (s - 6)²
