Hello!!
Well, the x-intercept is found when y = 0, so plug in y = 0:
-7x + 3(0) = 21
-7x = 21
x = -3
Therefore, the x-intercept of -7x + 3y = 21 is -3.
Hope this helps!! Let me know if you have ANY questions.
Answer: Length = 28cm
Width = 7cm
Step-by-step explanation:
Let the width be represented by x.
Since the length is four times its width. Therefore, the length would be:
= 4 × x = 4x
The perimeter of a rectangle is calculated as:
= 2(length + breadth)
Therefore, 2(4x + x) = 70
2(5x) = 70
10x = 70
x = 70/10
x = 7
Therefore, width = 7cm
Length = 4x = 4 × 7 = 28cm
Answer:
32 robberies
Step-by-step explanation:
To find the amount here, divide 64 by 2 (or multiply by 1/2).
64 / 2
How many times does 2 go into 6? (3)
3-

32 robberies
Answer:
21 books are on each shelf.
Step-by-step explanation:
To solve this you need to divide 130 and 6 so you should get 21 with a remainder of 4 which is the amount of books on each shelf and the amount of books that are left over.
I hope this helps :D
