Answer:
There are 6/5 white, 2 green, and 14/5 black
Step-by-step explanation:
Think of it like this.
First we add up everything.
3x+5x+7x = 6kg
15x=6
We find x and plug it in to the equation.
x=2/5
3*2/5=6/5 (6/5 is white)
5*2/5=2 (2 is green)
7*2/5=14/5 (14/5 is black)
There are 6/5 white, 2 green, and 14/5 black
Well for solving arithmetic sequences you have to add the numbers like for example if you had 2,4,6,8 The Common ratio would be 2 because you're constantly adding 2. Now for a geometric sequence it's a little different instead of adding the numbers you use multiplication to solve those ones so if the numbers were 4,16,64,256 the common ratio would be 4.
Now here comes the answers. For the matching :)
1. B Arithmetic, common difference is 2.
2. C Arithmetic, common difference is -4.
3. D Geometric, common ratio is 2.
4. A Geometric, common ratio is 0.5.
Hope This Helps You! Have A Wonderful Day. :)
Answer:
920
Step-by-step explanation:
8% of 1000 is 80
1000 - 80 = 920
Answer:
From the above image when the input of f(x) is 9 the output is 1
So f^-1(1) is just the reverse when the input is 1 the output is 9
So f^-1(1) = 9
Hope this helps
Answer:
I believe the inequality would be: p+2x3<40
Step-by-step explanation:
Not exactly sure if it is correct but p (number of pencils Sarahi has) added too the 2 more she finds, and then x3 (when she triples her amount). This is less then (<) what Damaris has (which is 40) so it would be p+2x3<40.
Again not sure if its completely correct, but i hope it helps :,)
