Answer:

2/13,140

4/105,120

6/40,832

8/35,100 or 6/23,400

Step-by-step explanation:

Cala's car is 2 years old, drives 18 miles per day times 365 days in a year times 2 years old is 13,140 miles in 2 years.

Lara's car is 4 years old, drives 72 miles a day times 365 days in a year times 4 years old is 105,120 in 4 years.

Jamal's car is 6 years old, drives 64 miles per day times 365 days a year times plus 56 miles a week times 52 weeks in a year times 6 years old is 40,832 in 6 years.

Ali's car was 2 years old when he got it 6 years ago. His car is 8 years old and he drives 15 miles per day times 52 weeks in a year for 5 days each week, times 6 years is 23,400miles in 6 years. If you average what he drives per year and add that to 23,400, the car has approximately 35100 miles in 8 years.

Alright! I'll help you. Let me tell you what's ratio, rate unit rates all about! :D

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

What is the difference between a unit rate and a ratio?

Guide the discussion so that students understand that a ratio is simply the quotient of two numbers, while a rate is the ratio of two measurements that have different units (like miles and hours, or dollars and ounces). Reinforce the fact that a rate is usually expressed in per unit form, where the denominator is 1.

What are some examples of ratios?

In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second. For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).

Is a rate always a ratio?

Rates and ratios. ... A rate is a little bit different than the ratio, it is a special ratio. It is a comparison of measurements that have different units, like cents and grams. A unit rate is a rate with a denominator of 1.

How do I find the unit rate?

To get the unit to equal 1, divide both numbers by the denominator; your answer is the number you get by dividing the numerator by the denominator. Use this method to calculate unit cost, too—you're calculating how much 1 item is worth, after you're given the amount that multiple items cost.

Here are some questions and how to answer them to help you! I hope this helps you! c:

If u subtract 17 from my number and multiply the difference by -7, the result is -35.What is my number
Kryger [21]

Let x = your number.

(x - 17) * -7 = -35. Divide each side by -7.

(x - 17) = 5. Add 17 to each side.

x = 22.

Your number is 22
