Answer:3(2x+7)-4=53-3x
6×+21-4=53-3x
6x+3x=53-21+4
9x=32+4
9x=36
X=36÷9
X=4
Step-by-step explanation:
125% as a fraction would be 125/100, which you can simplify to 5/4, or 1 1/4.
125% as a decimal would be 1.25, because you would do the sum 125 ÷ 100 = 1.25
I hope this helps!
Answer:
Speed of boat in still water is 6km/h
Speed of current is 4km/h
Step-by-step explanation:
We know speed = distance / time
Let the speed of boat in still water be x
Let the speed of current be y
Hence the speed of boat, down stream =
Distance downstream = 20km
Time taken = 2 hours
We have
......(1)
Speed of boat upstream =
Distance upstream = 4
Time taken = 2
We have
...(2)
Adding (1) & (2)
Substituting in (1) we get
Take 4,000 times 12 to get 48,000. that’s how much A costs.
B is a little harder. you have to take (2,300+300)x12+(4*250). this equals $32,100
the correct answer would be B.
Answer:
9
Step-by-step explanation:
List out the factors of the three numbers.
18: 1, 2, 3, 6, 9, 18
36: 1, 2, 3, 4, 6, 9, 12, 18, 36
45: 1, 3, 5, 9, 15, 45
The largest number that all three of these lists share is 9, so 9 is the GCF.
