Let d = # digital cameras
Let m = # manual cameras
d + m = 240 equation 1
(d-82) = 3(m-26) equation 2
d - 82 = 3m - 78
d - 3m = 82 - 78
d - 3m = 16 equation 2 simplified
We have two equations with 2 unknowns:
d + m = 240
d - 3m = 16 subtract equation 1 from equation 2
---------------
-4m = -224
m = -224/-4
m = 56
d + m = 240
d = 240-m
d = 240-56
d = 184
He started with 184 digital cameras and 56 manual cameras
Answer:
X = 9
Step-by-step explanation:
Write Equation: 20(x+1) = 200
Distribute 20: 20x +20 =200
Subtract 20: 20x = 180
Divide by 20x to leave x by itself: X=9

Answer:
D
Step-by-step explanation:
If the least it can be is 12, that means that with will have to be equal to 12
so mark out a and b
It also said the <u>least</u>, this means it can not be less than it.
Put these two together and you get D) k is greater than or equal to 12
