There were 287 music books and 134 science books in the store. After some books were sold there are 159 books left. How many boo
stiks02 [169]

Answer:

262 books sold

Step-by-step explanation:

This is a very vague word problem, but if it truly is just asking the amount of books sold (regardless of music or science), here's how to get the answer:

1. 287+134=421 - first you want to add together the two types of books to get the total amount of books in the store

2. 421-x=159 - create an equation and solve.

3. -x=-262 - follow order of operations and subtract 421 on both sides in order to isolate the variable

4. x=262 - divide each side by -1 to make the variable positive.

If you'd like an easier way, you can just:

1. 421-159=262 - it's easier, but my math teacher would count us wrong if we didn't do equations a specific way. Good luck!

6 students want lemonade and 12 students
Ksenya-84 [330]

Answer:

2:1

Step-by-step explanation:

well we show ratio by the sign ' : '

ratio of iced tea to lemonade= 12:6

now we reduce it to minimum by dividing it with same number.

12 is divisible by 6

so,

the reduced form is = 2:1

therefore,

ratio of the  number of students who want iced tea to the  number of students who want lemonade = 2:1.

Sec={ }
Eduardwww [97]

Answer:

A choice

Step-by-step explanation:

sec is defined as 1/cos.

cos is again defined as adjacent to hypotenuse.

We know that adjacent is x and hypotenuse is r.

Therefore:- cos is x/r

Now sec is 1/cos = 1/(x/r)

1 ÷ x/r is 1•r/x

Thus:-

sec is r/x
