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!
Hello! I would love to help!
Alright, we need to add all the fractions the problem gives us in order to find the answer. However, first, we need to find a common denominator.
So, what number can 2, 4, and 3 all go into?
The lowest number is 12. So, let's call 12 our common denominator.
Now, let's turn all the fractions to 12 as the denominator.
3/4= 9/12
1/2= 6/12
1/3 =4/12
Okay! Let's add the new fractions!
9/12+6/12+4/12=19/12
Let's turn it into a mixed number!
1 7/12
That's the answer!
Hope this helps! Comment if you have any questions!
In total they have $80 so that means Carlos have 35 Jeremy have 25 and Michele have 20 then 20 divide 80 gives u the percentage out of 100 the answer is 25
Parallel,
That chart probably relates to a transversal line you have above it with the numbers on the 3 lines. When it says "Parallel lines" it means what lines are parallel between the two given numbers. Example: Question a) is saying
Angle 10 is congruent to Angle 15, therefore what two lines that they're on or next to are parallel. In many cases, it would be the ones that they're on.
Converse,
The "Converse" is also known as "Alternate Interior Angles". Meaning angles that are on the same side of the transversal and are inside of it. Example: On the bottom of your page (near question 2) the angles 4 and 5 are transversals and so is 3 and 6. So just write down the converse of each given value or angle.
Hope this helped!
