Answer:
Step-by-step explanation:
To calculate slopes use the equation rise / run.
So count how many boxes up and divide that number by the number of boxes across to find the slope.
Make sure that you are using exact point on the slope (where the dots are on the line) to make it easier to calculate.
Also start from the left-most dot (look at slope B example)
For example for the slope of A:
2 blocks up, 5 blocks to the right so the slope is 2/5
But for slope B, since the first dot is higher than the second dot:
5 blocks down (-5), 1 block right so the slope is -5/1 or just -5.
Answer:
3cd+3 1/3c- 3d
Step-by-step explanation:
6 cd+ 3 c- 7 d- 3 cd+ 4d+ 1/3 c
6 cd - 3 cd = 3 cd First term
3c + 1/3c = 3 1/3c Second Term
4d - 7d = -3d Third Term
Combine all terms to get:
3cd+3 1/3c- 3d
Answer: c. 66
Step-by-step explanation:
Add 76 and 38.
76+38 = 114
Take 180 minus 114
180-114 = 66
First point to be noted here is, the shelf and the book are 5 inches wide. So it is perfect to hold the book.
The shelf is 56 inches tall and the book is 4 inches thick. To find the number of books Linda can arrange on the shelf, just divide 56 by 4
Number of books Linda can arrange on the shelf = 56 ÷ 4 = 14 books
