Final answer:

To solve 4.65 = x - 2.35, we add 2.35 to both sides, resulting in x = 7, indicating you had $7 initially.

Explanation:

Let's create a mathematical problem for the equation 4.65 = x - 2.35. Imagine you had $4.65 and you spent $2.35 on a snack. You want to calculate how much money you had before buying the snack. To solve this equation, follow these steps:

Add 2.35 to both sides of the equation to isolate the variable x on one side. So, it becomes 4.65 + 2.35 = x.

Combine like terms on the left-hand side, which gives x = 7.

Therefore, you initially had $7 before spending $2.35 on a snack.

The ratio of fiction books to total books is 3:4 if Rita reads 3 times as many fiction books as nonfiction books.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that:

Rita reads 3 times as many fiction books as non-fiction books.

Let x be the number of non-fiction books

The number of fiction books = 3x

Total books = x + 3x

Total books = 4x

The ratio of fiction books to total books = 3x/4x

The ratio of fiction books to total books = 3/4

The ratio of fiction books to total books = 3:4

Thus, the ratio of fiction books to total books is 3:4 if Rita reads 3 times as many fiction books as nonfiction books.

Final answer:

The original price of the jeans before the 15% off sale was $13.53, calculated by dividing the sale price of $11.50 by 0.85.

Explanation:

To determine the original price of the jeans before the sale, we must first understand that the final price of $11.50 represents 85% of the original price, since the jeans were on a 15% off sale. To find the original price, we divide the sale price by 0.85 (which is 85% expressed as a decimal).

The calculation is as follows: Original Price = Sale Price / 0.85 = $11.50 / 0.85

When we do this calculation, we get:

Original Price = $13.53 (rounded to the nearest cent)

Therefore, the jeans were originally priced at $13.53 before the 15% discount was applied.

Final answer:

The original price of the jeans before the 15% sale was found by dividing the sale price, $11.50, by 0.85 which equals $13.53.

Explanation:

To determine the original price of the jeans before the 15% off sale, you consider that the sale price represents 85% of the original price (100% - 15% = 85%). Since the jeans were sold for $11.50 after the discount, you can set up the equation 0.85 × (original price) = $11.50. To solve for the original price, you would divide $11.50 by 0.85.

The calculation would look like this:

Therefore, the original price of the jeans was $13.53 before the sale.

To calculate the Black Friday price of the TV, first determine 30% of the original price, which is $75. Subtract this discount from the original price of $250, which yields a Black Friday price of $175.

The subject of this question falls under Mathematics, specifically dealing with percentages. The price of the TV on Black Friday would be calculated by first determining the discount amount, which is 30% of the original price of $250.

Calculate 30% of $250 by multiplying 250 by 0.30 (30/100). That gives you $75.

The Black Friday price of the TV is the original price minus the discount amount. Therefore, $250 - $75 equals $175. So, the price of the TV on Black Friday would be $175.

the unit rate of the situation is 6 necklaces made per hour.

The same attribute is expressed using a unit conversion but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.

Given that 18 necklaces were made in 3 hours

Since,

in 3 hours necklace made = 18

in 1 hour necklaces made = 18/3

in 1 hour necklaces made = 6 per hour

Therefore, the unit rate of the given situation is 6 necklaces made in one hour.

0.625 inches on the map represents 1 mile.

To find how much distance on the map represents 1 mile when [tex]\frac{1}{2}\ inch[/tex] represents [tex]\frac{4}{5}\ mile[/tex], set up a proportion.

If [tex]\frac{1}{2}\ inch = \frac{4}{5} \ mile[/tex], then we can set up the equation:

x inches = 1 mile

First, we recognize that:

Next, using the proportion, we can set up and solve for x:

[tex]\frac{0.5\ inch}{0.8\ mile} =\frac{x\ inch}{1\ mile}[/tex]

Cross-multiplying gives:

0.5 * 1 = 0.8 * x

0.5 = 0.8x

Solving for x:

[tex]x = \frac{0.5}{0.8}[/tex]

x = 0.625 inches

Therefore, 0.625 inches on the map represents 1 mile.

The product of a number and its reciprocal is always 1, because multiplying a number by 1 divided by itself simplifies to 1.

The product of a number and its reciprocal is always 1. This is because a reciprocal is defined as 1 divided by the number. For any non-zero number x, the reciprocal is [tex]\frac{1}{x}[/tex]. Therefore, when you multiply a number by its reciprocal, x × [tex]\frac{1}{x}[/tex], you are essentially multiplying the number by 1 divided by itself, which simplifies to 1.

For example, the reciprocal of 2 is [tex]\frac{1}{2}[/tex], and when you multiply 2 by [tex]\frac{1}{2}[/tex], the product is 2 × [tex]\frac{1}{2}[/tex] = 1. This concept is crucial in mathematics, as it underlies the operations of division and multiplication, where division by a number is the same as multiplying by its reciprocal.
