8th grade math!! need to get a good grade!

Answers

Answer 1

Answer:

Bonnie :

(0,12),(1,16)

Slope = (16 - 12) / (1 - 0) = 4/1 = 4

So Bonnie is adding $ 4 every week to her savings

Bobby :

y = 12x + 4

The slope here is 12.....so he is adding $ 12 every week to his savings

Therefore, the rate at which Bobbie is adding to his savings each week is (12 - 4) = $ 8 more then the rate at which Bonnie is adding to her savings account each week

This table shows the populations of the four largest cities in the state of Wyoming. How many more people live in Cheyenne than in Laramie?

Answers

Answer:

28650

Step-by-step explanation:

just subtract 59,466-30,816

The number of more people who live in Cheyenne than in Laramie given the population of each city in the state is 28,650 people

How many more people live in Cheyenne than in Laramie?

Population can be defined as the total number of people living in a particular geographical location at a period of time.

Population of Cheyenne = 59,466

Population of Laramie = 30, 816

The number of more people who live in Cheyenne than in Laramie = Population of Cheyenne - Population of Laramie

= 59,466 - 30, 816

= 28,650 people

Hence, 28,650 more people live in Cheyenne than in Laramie.

i dont know what to say, bro

Step-by-step explanation:

just kidding $72.52

Step-by-step explanation:

A gallon of gasoline costs $2.96.

Your car can travel the distance on each gallon of gasoline = 28.8 miles

Your length of the trip = miles =

First we calculate the total use of gasoline on the trip.

∵ By 1 gallon gas of gasoline you can cover the distance = 28.8 miles

∴ to take miles trip gasoline used =

= 24.5 gallons

Since the cost of one gallon gasoline = $2.96

∴ The cost of 24.5 gallons of gasoline = 24.5 × 2.96

= $72.52

You spend $72.52 on gasoline for the trip of miles.

Step-by-step explanation:

-1 can also be written as -1/1

the lowest common denominator is 5 so re write the as 3/5 - 5/5

-3/5 - 5/5 = -8/5 = -1 3/5

-2 - 1 3/5 = -3 3/5

The distance between the numbers -2(³/₅) and -1 will be -3³/₅.

What is a number line?

A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R."

The distance will be calculated as;-

-1 can also be written as -1/1 the lowest common denominator is 5 so rewrite the as 3/5 - 5/5

-3/5 - 5/5 = -8/5 = -1³/₅

-2 - 1³/₅= -3³/₅

Therefore, the distance between the numbers -2(³/₅) and -1 will be -3³/₅.
