Answer:

x=10

Step-by-step explanation:

3(4x-12) = 84

Divide each side by 3

3/3(4x-12) = 84/3

4x-12 =28

Add 12 to each side

4x-12+12 = 28+12

4x= 40

Divide each side by 4

4x/4 = 40/4

x = 10

Each day that a library book is kept past its due date, a $0.30 fee is charged at midnight. Which ordered pair is
mihalych1998 [28]
Let's say the number of days library book is late is X, and the total fee is Y.

Liability charges $0.30 dollars as a fee for being 1 day late,

For being 1 day late, fee charge is: 1* $0.30
So, for X days the charge would be: X*$0.30.

Total charge for being X days late is Y, Which means: Y= 0.30 * X.

Now We would have to check all the viable solutions in the answer to see if they satisfy the equation Y= 0.30 * X

Option one(-3, -0.9) and two (-2.5, -0.75) Would not be a viable solution because the value of number of days can not be negative and in option one and two, value of days -3 and -2.5 is negative.

Option three(4.5, 1.35) can not be correct because library charges fee for a full day so the number for days would be a whole number. Library would not charge for 4.5 days, they would either charge of 4 days or 5 days because 4.5 is not an whole number.


Option four(8, 2.40) is the correct answer because it satisfies our equation;

Y= 0.30 * X

2.40= 0.30 * 8

2.40 = 2.40.


Fourth option (8, 2.40) is the only viable solution to this question.

You mix 1/2 cup of oats for every 1/4 cup of honey to make 12 cups of granola. How much oats and how much honey do you use?
Shalnov [3]
<h2>Answer: </h2>

I will use 6 cups of oats and 1 cup of honey to make 12 cups of granula .

<h3>Explanation: </h3>

Let x be the number of cups of oats and let y be the number of cups of honey. Given statement can be expressed in fractions as

½ x / ¼ y = 12

4x/2y = 12

2x/y = 12

x/y = 12/2 = 6/1

x=6, y=1

Therefore number of cups of oats = x = 6 cups

Number of cups of honey = y = 1 cup
