Answer:
D, Y=2x-4
Step-by-step explanation:
The easiest way to solve this is by substitution. Plug in 3 into the X of each equation to see if you get 2 as your outcome. Double check by doing the same with 8 and seeing if 12 is the outcome. Once you do this, problems like the one should be a piece of cake.
Answer:
Ok so you have to do this
Step-by-step explanation:
Jill ran faster. I know because I compared both of their unit rates.
Jack's unit rate is 5/42.5 = 0.118 mile per minute (rounded)
Jill's unit rate is 3/23.25 = 0.129 mile per minute (rounded)
Jill runs a greater part of a mile per minute than Jack does.
She is faster. There's no getting around it.
Answer:
3
Step-by-step explanation:
Assuming a typo in your question. Sqrt(9) = 3
Let's start with the smallest prime number 2
60/2 = 30
Divide that result over 2
30/2 = 15
We can't divide this by 2 because 15/2 = 7.5 isn't a whole number
Let's move onto 3
15/3 = 5
The result is a prime number, so we stop.
The values we divided as denominators were: {2, 2, 3}
We add the result 5 to the set to completely list all of the prime factors of 60
The prime factorization would be
<h3>60 = 2*2*3*5</h3>
which is the same as saying
<h3>60 = 2^2*3*5</h3>
