➷ 847) You need to cross multiply
Multiply both sides by (x - 7) and 3
This is what you should get:
Now we just need to get like terms on the same side.
Add 42 to both sides and subtract 2x from both also
Now you get this:
848) It's the same principle in this one too.
Multiply both sides by (x - 13) and 11
You should get:
Subtract 11x from both sides and add 156 also
Now you get:
849) Multiply both sides by x
You should get:
Add 4x to both sides and add 12 also:
Divide both sides by 5
850) Multiply both sides by x
You should get:
Subtract x from both sides:
Divide both sides by 3:

Assume that each material in each category has an equal chance of being selected.
Categories:
(a) Type of wood used to make the cabinet: birch, maple, cherry.
Each type of wood has a probability of 1/3 to be selected.
(b) Type of finish: transparent, semi-transparent.
Each type of finish has a probability of 1/2 to be selected.
(c) Knob: bronze, steel, wood.
Each material has 1/3 probability to be selected.
Each event (selecting material for the cabinet, for the finish, and for the knob) is an independent event.
Therefore
Probablity(birch wood AND bronze knob) = (1/3)*(1/3) = 1/9
Probability(wood knob) = 1/3
Probability(transparent stain) = 1/2
Probability(cheryy wood AND semi-transparent stain) = (1/3)*(1/2) = 1/6
Answer:
2d+44
Step-by-step explanation:
Multiply all numbers without variables:
11x4=44
Add equations:
2d+44
Hence, the correct answer is 2d+44
For the cost to be the same:
18648+23.5b=83556+10b subtract 10b from both sides
18648+13.5b=83556 subtract 18648 from both sides
13.5b=64908 divide both sides by 13.5
b=4808
So if 4808 books are produced the cost of both methods is the same.
