Part B: How much sooner could you purchase the bicycle is you had a coupon for $20 off and saved $8.75 every week? Explain your reasoning. 

PLEASE HELP! I'M IN 7th GRADE...AND I NEED TO GET MY MATH HOME WORK DONE, AND MY PARENTS AR'NT HOME TO HELP MEE..THANK YOU!

Answers

A. since you already have $43.50 already saved you subtract that from the amount the bike cost so you can see how much more needs to be left to save and that gives you $72.50. Then you divide the amount your saving up every week from that. So $72.50 divided by $7.25 is 10 and thats how many weeks it will take to save.

B. Since you still have that $43.50 saved and you have a coupon for $20 dollars off . Add those together to see how much you have saved up which equals $63.50. The bike is $116 so you subtract the amount you have for the bike from $116 which is $63.50 and that equals $52.50 and thats how much more money you need. Then divide how much money needed by the amount your saving up a week, which is $8.75. So $52.50 divided by $8.75 is 6 and thats how many weeks it will now take to get the bike.

What is 83/9 as a whole or mixed number

Answers

mixed number: 9 2/9

1. How many 9's go into 83 
2. It is 9 because 9*9 = 81                         9*10=90 is bigger so not possible
3. 2 is left because 83-81 = 2
4. And don't forget the denominator
9 goes in to 81-- 9 times.
83 minus 81 is 2...as a mixed number of is that 9 2/9

Rosa needs to mail two packages one weighs five Eighths of a pound and other ways two thirds of a pound what is the total weight of the to packages ?how much heavier is Rosa second package than the first ?

Answers

The total weight of the packages is 5/8 = 0.625 + 2/3 =  0.666 i.e. 1.291 Pound.
TO be precise 2/3 would be 0.666666667, so technically the total weight of the two packages is 1.291666667 Pound.
To calculate the exact difference between Rosa's first and second package, we would have to subtract the weight of the second package with the weight of the first package: 0.666666667 - 0.625 = 0.041666667.
So, Rosa's second package is heavier by 0.041666667 pound.
so one weighs 5/8 and the other weighs 2/3 pound
make bottom number same
multiply 5/8 by 3/3 and multipy 2/3 by 8/8
5/8=15/24
2/3=16/24
add them together
15/24+16/24=31/24=1 and 7/24 pound
total weight is 1 and 7/24 pound

1st package=15/24
2nd package=16/24
subtract
16/24-15/24=1/24
the second package is 1/24 pound heavier

Answer:

Answer is C!

Step-by-step explanation:

The -2 is the y intercept and 1/3 is the slope.

The slope determines the angle of the line and the Y intercept determines how high or low that line is placed. To graph it I like to use a method called rise over run. First I identify the Y intercept then I identify the slope. From there I start at the Y intercept and Find the line. Definitely look up some tutorials on rise over run to plot equations!
