How did you do 2 step equations but in a word problem? Thankyou

Mathematics
1 answer:
dem82 [27]3 years ago
8 0

Answer:

A example:  A customer brought 5 quarts of lemonade from Leah's stand. She also tipped Leah an additional $2. The customer finally paid a total of $27 including the tip. How much is each quart of lemonade worth? If x is what the lemonade is worth, write an equation to figure out the total.

In this problem, the x is what the lemonade is worth. So you should start with a 5x. The customer also tipped $2. So you should add 2 to the 5x. We also know the total, 27.

With the information we can form an equation.

5x + 2 = 27.

To solve, we can subtract 2 from both sides and finally dived by 5 on both sides as well. Your final answer should be x = 5.

Hopefully this is what you're looking for, sorry for being late!

How would the domain and range of the function y = one-fourth x minus 6 be determined? Explain.
Liono4ka [1.6K]

Answer:

Domain = ( -∞ , ∞ )

Range = ( ∞ , ∞ )

Step-by-step explanation:

A function is given to us and we need to find the domain and range of the given function .

<u>The </u><u>function</u><u> </u><u>:</u><u>-</u><u> </u>

\rm \implies y = \dfrac{1}{4}x - 6

Definitions :-

  1. <u>Range </u>:- The range is the set of all valid y values .
  2. <u>Domain</u> :- All real numbers except where the expression is undefined.

In this case, there is no real number that makes the expression undefined. Therefore the domain will be :-

<u>Domain</u><u> </u><u>:</u><u>-</u><u> </u>

\rm Domain = ( -\infty , \infty )

or

\rm Domain = \{ x | x \in \mathbb{R} \}

<u>Range </u><u>:</u><u>-</u><u> </u>

\rm Range = ( -\infty , \infty )

or

\rm Range = \{ y | y \in \mathbb{R}\}

What is the value of y in the equation 5x + 2y = 20, when x = 0.3?
Hatshy [7]
<span>5x + 2y = 20

put x=0.3

5(0.3) + 2y = 20

2y = 20-1.5
2y = 18.5
y = 9.25
