List the multiples of both 12 and 9:
12, 24, 36, 48, 60
9, 18, 27, 36, 45
The lowest common multiple is 36.
This will make the fixtures and bulbs equal.
This means they bought 3 packages of light figures 3 x 12 = 36)
And bought 4 packages of bulbs ( 4 x 9 = 36)
Answer:
Step-by-step explanation:
The meals for all 9 cost 9x5 = $45
225-45= $180 which represent the entrance fees for all 9.
We divide that to 9 and we get the entrance fee per student!
180/9 = $20 / fee per student!
Answer:
Option A
Step-by-step explanation:
Option A
f(x) = -3(x + 7)(x + 4),
Remember that to solve for the x-intercepts we equate y to 0,
-3(x + 7)(x + 4) = 0
Using the zero product property,
x + 7 = 0, x + 4 = 0
x = - 7, x = -4
x -intercepts: (- 7, 0) & (- 4, 0)
Hence proved.
