Given the midpoint and one endpoint of a line segment, find the other endpoint.
Endpoint: (-9, -1), midpoint: (8, 14)
answer
system : 8L+ 4S = 120
L + S = 20
There are 10 small packs and 10 large packs
step by step answer :
to form the two systems, we have to determine the catagories of the 2 equations : one for money and one for the no of packs
after forming the two equations we simply put the numbers in the same order put above on the calculator ( mode 5:1) and the calaculator will answer it in seconds . 10 small packs and 10 large packs.
To check your answer , substitute the letters with their values and if both equations gave you the same value at the end then your answer is correct!
Answer:
4
Step-by-step explanation:
- u·(u−v)+v·(v−u)
- u^2 - uv + v^2 - vu
- u^2 - 2uv + v^2
- (u -v)^2 OR (v-u)^2
- (4.3 - 2.3)^2
- 4
Answer: 6 hours or 360 minutes
Step-by-step explanation:
First find out how long it takes to deliver to one house.
Convert hours to minutes.
2.5 x 60 = 150 minutes total
Divide to find the time per house
150 minutes / 130 houses = 1.15 minutes per house
Now multiply this rate by the number of houses (312).
312 x 1.15 = 360 minutes
If you want it in hours then divide by 60.
360/60 = 6 hours.
Answer:
40
Step-by-step explanation:
LCM
multiples of 5: 5, 10, 15, 20, 25, 30, 35, <u>40</u>
multiples of 8: 8, 16, 24, 32, <u>40</u>
<u />
the least (smallest) number that is a multiple of both 5 and 8 is 40
