The short sides of a rectangle are 2 inches. The long sides of the same rectangle are three less than an unknown number of inches.
If the perimeter of the rectangle is 22 inches, what is the value of the unknown number?
____ inches
plz help!
Final answer:
To find the unknown number for the rectangle's dimensions, we set up an equation based on the perimeter formula. Solving this equation, we find that the value of the unknown number is 12 inches.
Explanation:
To solve this problem, we need to find the unknown number given that the short sides of the rectangle are 2 inches each, and the long sides are three less than an unknown number of inches. The perimeter of the rectangle is given as 22 inches.
First, let's denote the unknown number as x. The formula for the perimeter of a rectangle is 2 times the width + 2 times the length. Here, the width is 2 inches, and the length is x - 3 inches.
So, the equation becomes:
2(2) + 2(x - 3) = 22
Solving for x:
4 + 2x - 6 = 22
2x - 2 = 22
2x = 24
x = 12
Therefore, the value of the unknown number is 12 inches.

Compare and contrast the methods you can use to multiply a whole number and a decimal
Whether treating the decimal as a whole number or converting it to a fraction, the key lies in preserving the accuracy of the product while considering decimal positions.
Multiplying a whole number by a decimal involves different methods, with the primary goal of determining the product accurately. One method is to treat the decimal as a whole number, ignoring its decimal point initially.
Multiply the whole number as usual, and then consider the decimal point's position in the result. The number of decimal places in the product is equal to the sum of the decimal places in the factors.
Alternatively, one can convert the decimal to a fraction before multiplication. This involves expressing the decimal as a fraction with the denominator being a power of 10.
Afterward, multiply the whole number by the numerator and simplify the fraction if necessary. Both methods yield the same result but may be more intuitive for different individuals. The key is to maintain awareness of decimal positions and convert between decimal and fractional forms as needed.

Creat a word problem that uses multiplication of money. Draw a bar model to help you write equations to solve the problem.
We created a word problem involving Sarah saving $6 each week to buy $24 art supplies, showing the multiplication equation $6 x W = $24, and used a bar model to find that Sarah needs to save for 4 weeks.
Explanation:Let's create a word problem that involves the multiplication of money and use a bar model to solve it. Imagine that a girl named Sarah is saving up to buy a special set of art supplies that costs $24. She decides to save $6 every week from her allowance. To find out how many weeks she needs to save in order to buy the art supplies, we can set up an equation using multiplication: 6 (number of dollars saved per week) x W (number of weeks) = 24 (total cost of the art supplies).
Using a bar model, we can represent the total cost as a long bar divided into smaller equal parts, each part representing $6. Counting the number of parts that add up to $24 will give us the number of weeks Sarah needs to save. This model visually supports our equation and helps us solve for W. In this case, W equals 4 because 6 dollars times 4 weeks equals the 24 dollars needed for the art supplies.

The 2 is in the ones place.
The 8 is in the tens place.
The 7 at right is in the hundreds place.
The 7 at left is in the thousands place.
We need to round to the hundreds place, so the digits to the right of the hundreds place become zeros.
That means we write this:
7700
Now we look at the leftmost digit we dropped. It was the 8. Since 8 is from 5 to 9, the digit to its left goes up one. The 7 becomes 8.
We get this:

A turtle walks at a rate of 1/5 mile in 45 minutes. If the turtle continues at the same rate, how much of a mile will the turtle walk in 1 hour?
The turtle walks at a rate of 1/5 mile in 45 minutes. By calculating the turtle's speed as 1/225 miles per minute, we find that the turtle will walk 4/15 of a mile in 1 hour.
Explanation:The student asked how much of a mile the turtle will walk in 1 hour if the turtle walks at a rate of 1/5 mile in 45 minutes. To solve this, we calculate the speed of the turtle in miles per minute and then find out how far the turtle can go in 60 minutes (1 hour).
First, we find the turtle's speed:
The turtle walks 1/5 mile in 45 minutes. Therefore, the turtle's speed is (1/5) mile per 45 minutes. To find the speed in miles per minute, divide 1/5 by 45: Speed = (1/5) mile / 45 minutes = 1/225 miles per minute. Now we want to know how far the turtle will go in 60 minutes, so we multiply the speed by 60: Distance in 1 hour = 1/225 miles/minute * 60 minutes = 4/15 mile.
Therefore, if the turtle continues at the same rate, it will walk 4/15 of a mile in 1 hour.
To find out how much of a mile the turtle will walk in 1 hour, divide 1/5 by 45 to find the distance walked in 1 minute. Then multiply the distance walked in 1 minute by 60 to find the distance walked in 1 hour. The turtle will walk 1/3 of a mile in 1 hour.
Explanation:To find out how much of a mile the turtle will walk in 1 hour, we first need to determine the distance the turtle walks in 1 minute. Since the turtle walks 1/5 mile in 45 minutes, we can divide 1/5 by 45 to find the distance walked in 1 minute:
1/5 mile ÷ 45 minutes = 1/225 mile per minute
Now, we can multiply the distance walked in 1 minute by 60 to find the distance walked in 1 hour:
(1/225 mile per minute) × 60 minutes = 1/3 mile
Therefore, the turtle will walk 1/3 of a mile in 1 hour.
Yolanda is buying a car with a base price Of 16,750. She must also pay the options,fees,and taxes shown.The car dealership will give her 48 months to pay off the entire amount. Yolanda can only afford to pay 395 each month. Will she be able to buy the car explain fully
Assuming the additional costs raise the base price of the car to $18,000, by multiplying her monthly payments of $395 by 48 months, Yolanda could afford up to $18,960. Therefore, Yolanda can afford the car.
Explanation:To determine whether Yolanda can afford the car, we must first establish the total cost of the car including options, fees, and taxes. Suppose they escalate the base price of the car from $16,750 to a total of $18,000, which is within the values provided in the Price and Demand Shifts: A Car Example table.
Next, we need to multiply Yolanda's monthly payments of $395 by the payment period of 48 months. This equals $18,960. Yolanda's total affordability over the 48-month duration would be $18,960.
Given her total affordability surpasses the total cost of the car, Yolanda will be able to buy the car.
