Answer:
A
Step-by-step explanation:
plug in y and x, if you want to be sure of each answer
In the case of A) here are the 2 equations, y-2=x+4 and 3x+4=x+6
now plug in what a describes
x=1, y=7
7-2=1+4 and 7=7
Therefore the answer is A
Answer:
The answer is: 1. 5 minutes and 2. 133.3 meters
Step-by-step explanation:
To find how long it takes the cyclist to travel 2km at 24km / hour, set up the equation and cross multiply:
2 / 24 = x / 1
24x = 2
x = 2/24 = 1/12 of an hour or 60 / 12 = 5 Minutes.
To find how far he travels in 20 seconds:
Multiply 24 km by 1000 to get meters per hour. Divide by 3600 to get meters per second:
24000 / 3600 = 6.6 meters per second.
Multiply by 20 seconds to get the distance traveled in 20 seconds:
6.6 * 20 = 133.3
It's multily
f(x) time g(x) is basically what they wnat
so
(x^2+8x+15) times (5/(x^2-9))
hold a sec, first factor each
(x+3)(x+5) times 5/((x-3)(x+3))
we get
((x+3)(x+5)(5))/((x-3)(x+3))
(x+30 cancels out
((x+5)(5))/(x-3)
(5x+25)/(x-3)
3rd option
Answer:
1. 3.5% is 35/1000 as a fraction and 0.035 as a decimal.
2. 2.31 is 231% and 231/100
3. 23/25 is 92% and 0.92
4. 33% is 33/100 and 0.33
Step-by-step explanation:
For converting from fraction to decimal, simply divide the top by the bottom.
For converting from decimal to fraction, depending on how many places there are, you choose what to divide by. Ex: .002 (there are 3 places, it is divided by 1,000)
For fraction to percent, you divide the top by the bottom, make it a decimal, and move the decimal over two places to the right.
