1.5r+15=2.25r
Combine like terms: 1.5r+15-1.5r=2.25r-1.5r
15=0.75r
Get the unknown alone: 15/.75=.75/.75r
20=r or r=20 :)
Answeidk i tried to read it but I dont getit

Answer:
It's the first option! :)
Step-by-step explanation:
2x + 2k = m, right?
So, to bring 2k alone, we'll subtract 2x.
2k = m - 2x
Now, we'll divide both sides by 2! ^ _ ^
k = (m - 2x) / 2
That's pretty much just the (1)st option! :)
A.) 0.55
This is because the probability has to com out to 1 (technically 100%) so, 1-0.45 is 0.55 (these could all be percentages if you multiply them by 100)
Answer:
1728000
Step-by-step explanation:
You always work from the parenthesis first because of order of operation. You have 12( because 2 times 6) then mulitply 12 times 10. You get 120 then you multiply it but itself 3 times. 120 x 120 x 120= 1728000
