Answer: For a fence that has 18 posts he needs 36 rails.

Step-by-step explanation:

Hi, to answer this question we have to use proportions:

Each section use 3 vertical fence post and 6 horizontal rails

The proportion is = 3 post /6 rails

For 18 posts:

18 posts / x rails.

3 /6 = 18 /x

Solving for x:

x = 18 / (3/6)

x = 36 rails

For a fence that has 18 posts he needs 36 rails.

Feel free to ask for more if needed or if you did not understand something.

Four times the quotient of a number and 9 plus 14, how do I right it as an expression?
user100 [1]

The expression is written as (4n/9) + 14

What is an expression?

An expression or mathematical expression is a finite collection of symbols that is well-formed according to context-dependent norms. To assist identify the sequence of operations and other features of logical syntax, mathematical symbols can denote numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. Many writers differentiate between an expression and a formula, with the former referring to a mathematical item and the latter referring to a statement about mathematical things. For instance, is a formula. However, in modern mathematics, and particularly in computer algebra, formulae are considered as expressions that may be evaluated as true or false based on the values assigned to the variables in the expressions.

mckezie's rabbit ears 1/3 of a pound of food each day if mckenzie buys a 20 pound bag of food how many days will she be able to
Elan Coil [88]

Answer:

She can feed her rabbit for 60 days!

Step-by-step explanation:

Turn 20 into a fraction:

\frac{20}{1}

Make sure it has the same denominator:

<em>(Remember: what you do to one side, you must do to the other)</em>

\frac{20}{1} *\frac{3}{3}= \frac{60}{3}

This means that if the rabbit eats 1/3 of a pound a day, she will be able to feed her rabbit for 60 days.

Find the solution for the system of linear equations by elimination: -3x + y = 2, 4x - y = 4 Explain how you found the solution.
viktelen [127]

Answer:

x = 6 \\ y = 20

Step-by-step explanation:

1. Add the equations. The y's cancel out.

+ 4x - y =  + 4 \\  - 3x + y =  + 2 \\  -  -  -  -  -  -  -  \\ x = 6

2. Embed x in either equation and find y.

4x - y = 4 \\ 4(6) - y = 4 \\ 24 - y = 4 \\ 20 - y = 0 \\ y = 20
