Parallel: the lines have = slopes. We thus need 5/6 to equal 2/p. then 5p must equal 12, and p = 12/5. (answer)
Check: Is 5/6 = 2 / (12/5)? YES
Perp.: The lines have slopes that are negative reciprocals of one another.
Then -6/5 = 2/p, or
-6 2
---- = ----
5 p Thus, -6p = 10, and p = -5/3 (answer)
Answer:
The probability that a letter at random is from V is 5/26 or 19.23%
Answer:
x = - 7
Step-by-step explanation:
Given
- 2(x + 5) = 4 ← distribute the parenthesis by - 2
- 2x - 10 = 4 ( add 10 to both sides )
- 2x = 14 ( divide both sides by - 2 )
x = - 7
The value of unknown number n is 47, wrote by Ms. Morales.
<h3>What is defined by the term expression?</h3>
In mathematics, an expression is a sentence that contains at least two digits or variables and with at least each math operation.
Addition, simple arithmetic, multiplication, or division are all examples of math operations.
- a) Constant: a numerical value that is fixed.
- b) Variables: they have no fixed values. Values are assigned based on the requirement.
- c) Terms: could be constants, variables, or variables multiplied by constants/ (s). Each word in an expression is denoted by a '+' or '-' sign.
For, the given condition in question;
Ms. Morales wrote the sum of 5 copies of some number n.
Then again,
He again wrote 2 copies of the same unknown number n.
The expression becomes;
n = 42 + 5
n = 47
Thus, the value of the unknown value is found as 47.
