Answer:
(x+y) / 72
Step-by-step explanation:
Kate needs to read 2 books
she's not sure how many pages are in each book.
Let
Number of pages in the first book = x
Number of pages in the second book = y
Total pages of the two books = x + y
Kate's summer vacation = 72 days
she is planning to read the same number of pages each day of her summer vacation.
Number of pages she will need to read each day = (x+y) pages / 72 days
Number of pages she will need to read each day = (x+y) / 72
130/182*100= 71.42% would be your answer
It is given in the question that B is in between C and D.
Therefore
Substituting the given values of CB,BD and CD, we will get
Combining like terms, we will get
Now we need to move 4 to the right side by adding 4 to both sides, that is
Answer:
Step-by-step explanation:
Focus on #7. Let's combine the first two matrices inside round parentheses.
We get
-2 - 1
4 + 3
and so the original problems becomes
-3 4
3( [ ] + [ ] )
7 2
Combining the two matrices, we get the following:
1 3
3([ ]) = [ ]
9 9
4x²=4
Dividing both sides by 4 just to make x² stand alone..
4x²/4 = 4/4
x² = 1
Taking the square roots of both sides (this is so as to cancel the square in x)
x²=1
x= square root of 1(meaning what can we multiply two times to give us 1)
x= 1 or - 1 in ±1
1×1 =1
-1×-1=1
Yhe Zeros are 1,-1...
