i can
Step-by-step explanation:
Here it goes:
a. Because you have four blue marbles out of the 12 total marbles, the probability is 4/12. YOU MUST SIMPLIFY down to 1/3.
b. There are 12 marbles in the bag right now, and the probability is 4/12, you must add some marbles. 1/10 multiplied by 4 is 4/40. There are 4 blue marbles right now, and 40 minus the 12 there are right now is 38, so you would need to add 38 non-blue marbles.
Let
S=cost of software
4S=cost of computer
Total cost = $1200
=>
S+4S=1200
solve for S
5S=1200
S=240 (= cost of software)
Cost of computer = 4*240 = $960
Answer:
Step-by-step explanation:
4x² : 64x² = x : 36x²
4x² * 36x² = x * 64x²
144x⁴ = 64x³
x⁴/x³ = 64/144
x = 4/9
