Answer:
3.16 units
Step-by-step explanation:
The distance between the points P1 (6, 8) and P2 (7, 5)) can be solved by using the distance formula given as .
Let,
Plug these values into the distance formula.
Thus:
d = 3.16 (nearest tenth)
Distance between the two points in the graph is approximately 3.16 units
Answer:
13
Step-by-step explanation:
- x × (x + 9) = x² + 9x = 286
- x² + 9x - 286 = 0
- (x - 13)(x + 22)
- x = 13 or -22
- Since you cannot have negative length, it’s 13
Answer:
27 quarters and 37 nickels
Step-by-step explanation:
Nickels are 5¢
Quarters are 25¢
$8.60 is 172 nickels (860/5)
$8.60 is 34.4 quarters (860/25)
So then let's split it half-and-half.
425 and 435
425 would become 17 quarters.
435 would become 87 nickels.
This is still too much.
Now let's try 700 and 160.
700 would become 28 quarters
160 would become 32 nickels.
28+32=60.
This is a lot closer.
So now 27 quarters and 37 nickels. This works.
