General Idea:

When we are working with word problems, we need to follow the below steps:

<u>Step 1:</u> Assign variable for the unknown that we need to find.

<u>Step 2:</u> Write a meaningful mathematical equation using the sentence given

<u>Step 3:</u> Solve the equation by Performing reverse operation by Undoing whatever is done to the variable. Solving means find the value of the variable which will make the equation TRUE.

Applying the concept:

Step 1: Let x be the number of books that Brett can afford without spending more than his gift voucher amount.

Step 2: Writing mathematical equation based on the given sentence "Brett has a $30 online gift voucher. He plans to buy as many books as he can. The cost of each book is $4. There is also a single shipping charge of $2"

Online \; Gift \; Voucher=Number \; of  \; books  \; \times  \; Cost\;per \; Book \; + \; Single \; shipping \; charge

30=4x+2

Step 3: Solving equation

4x+2=30\\ Subtract \; 2 \; on \; both \; sides\\ \\ 4x+2-2=30-2\\ Combine \; like \; terms\\ \\ 4x=28\\ Divide  \; 4 \; on \; both \; sides\\ \\ \frac{4x}{4}= \frac{28}{4} \\ Simplifying  \; fraction \; on \; both \; sides\\ \\ x=7

Conclusion:

The number of books that Brett can afford without spending more than his gift voucher amount is <u>7</u> !!

On a shelf containing 53 comic books, 21 are Marvel titles, 17 are DC titles, 12 are Dark Horse titles, and 3 are Harvey titles.
Marizza181 [45]

Answer:

68% or \frac{36}{53}

Step-by-step explanation:

In order to find the probability of Geraldo selecting a comic that isn't a DC title, we have to subtract the amount of comics that are DC titles from the total amount of comics and then divide that number by the total amount of comics.

53 - 17 = 36

36/53 = 0.679

Geraldo has a 68% chance of choosing a comic that isn't a DC title.

The discriminant for the equation f(x)=6x^(2)-x+c is 73. What is the value of c?
Andrews [41]

Answer:

c = -3

Step-by-step explanation:

The discriminant  is 73, that means we have:

(-1)^2-4*6*c=73

then: 1-24c=73

or -24c= 73 -1

-24c = 72

Then c = 72/-24= -3

The answer is -3

Hope that useful for you.
