kenny has 9 more comic books than bobbie. together they have 95 comic books. define a variable. then write an equation that could be used to find the number of comic books they each have.

Answers

Answer 1

Answer: Number of comic books Bobbie has - b

95 = (9 + b) + b

Since 95 is the total number of comic books both boys have, it is equal to both boys' books added together. However, since we don't know how many books Kenny has, and only that he has 9 more than Bobbie, we can define that as (9 + b), or nine more than b. Then, we add b again, because (9 + b) is the number of books Kenny has, and if we add that to the number of books Bobbie has, it will equal the total of 95 comic books.

The school enrollment for Oakwood Elementary is shown in the graph. If the pattern continues, what will the school enrollment be in 2012? Question 19 options: 500 525 550 575

Answers

Answer:

Option B. 525 students.

Step-by-step explanation:

The school enrollment for Oakwood Elementary is shown in the graph.

The given graph is representing a linear function. So we will form the function first to calculate the enrollment in 2012.

Equation of the given line in the graph will be in the form of y = mx + c

where m is the slope and c = y- intercept

y-intercept = 300

this line passes through two ordered pairs (0, 300) and (1, 325)

Now the slope m = $(y-y')/(x-x')$

m = $(325-300)/(1-0)=25$

Therefore, equation representing the situation will be y = 25x + 300

Now we will put the value of x = year 2012 - year 2003 = 9 years

y = 25×9 + 300

y = 225 + 300

y = 525

Option B. 525 is the correct option.

Answer:

The answer is 525

Mr.and Mrs.Baker place 12-inch rulers end- to-end along the entire length of a rug.they each use 3rulers.about how many feet long is the rug?

Answers

There are 2 people measuring, each using 3 rulers.

2 times 3 equals 6.

12in. times 6 rulers equals 72 in.

12 in. equals 1 foot so 72/12 equals 6 feet.

The rug is around 6 feet long.

The equation is [(3•2)•12]/12. It is 3 times 2 because each Baker uses 3 rulers. It is then times 12 because each ruler is 12 inches. It is then divided by 12 because it says to label in feet and there are 12 inches in a foot. Remember to label feet with your answer.

How you be a very good maths improver

Answers

In order to improve in your math skills you have to study.
I know from experience.
You can get a tutor like I did. Some help some dont so choose wisely.
You should print out worksheets from online, if you dont have a printer just copy the question onto a piece of paper.
STUDY!
Everyday when you come home from school, review what you have done during math class so if you forgot some of it you refresh your mind. Do the same thing before you go to sleep.
Hope I helped!

Study by finding online games and printing out worksheets. Ask your parents or guardian to quiz you and MAKE FLASHCARDS! It helps so much. When you have a spare 5 minutes pull them out and study. Take extra notes in class than your teacher wants you to and rewrite them and highlight them. Find workbooks around your house. Ask your parents/guardian to make a math test for you or just print one out. Don't stress yourself with math, take a 10 minute break before doing more every 30 minutes. I used to HATE MATH but now it's ok because I do these things. MATH IS FUN!!!!
