Use distributive property.
Hope this helps!
Answer:
B) 14
Step-by-step explanation:
1/5 + 1/3 = x (don't worry, it's not algebra, I'm just using x as an example)
The common denominator is 15, so you multiply 5 by 3 = 15 and 1 by 3 = 3,
3/15 = 1/5
Then, multiply 3 by 5 = 15 and then 1 by 5 = 5, so it's
5/15 = 1/3
5/15 + 3/15 = 8/15 and then multiply 15 by 2 = 30 (number of students) and because you multiplied 15 by 2, you also multiply 8 by 2 = 16
So it is now 16/30, so you do 30-16 which is 14.
14 students chose Station M (doesn't sound like a good station).
Whoo! Let's go! (I'll stop being cringy now).
Answer:
this seems hard to do
Step-by-step explanation:
Answer:
x has to be -3 for the answer to be 0
Step-by-step explanation:
x(t) = 20t
y(t) = 40t - 5t^2
Since we are only interested in comparing the two at time t = 5 seconds, we plug in 5 everywhere we see the variable t and then compare x and y
x(5) = 20(5) becomes x(5) = 100
y(5) = 40(5) - 5(5)^2 becomes y(5) = 200 - 125 and then y(5) = 75
The ratio of y to x can be expressed as: y/x, so we can say the ratio is equal to 75/100 or 0.75
Answer: 0.75
