Combine all paper clip colors together (3 red+ 5 yellow+ 6 silver) to get 14 paper clips in all.
The number of red clips are 3.
Since it is asking for ratio of total paper clips to red paperclips, the number of total paperclips goes in the ratio goes first and red paperclips second. 14:3.
This ratio cannot be simplified any further so A is the correct answer
Hope this helps!
if you're solving for x it's -30
steps: x/-3+20=30
first subtract 20 from both sides then you'll have
x/-3=10 then multiply both sides with -3
you should have x by itself and -30 on the other side
answer x=-30

Step-by-step explanation:
1970 to 2010 = 40 years
New price = .35*(1.1)^40
New price = .35*45.26
New price = .15.84
Answer:
(5, 18) and (-3, 2)
Step-by-step explanation:
We have two equations:
Let's eliminate y by setting the two equations equal:
Move all the terms to one side:
Factor:
Solve for x:
x - 5 = 0
x = 5
OR
x + 3 = 0
x = -3
Plug each of these values of x into any of the two original equations:
y = 8 + 2 * 5 = 8 + 10 = 18
y = 8 + 2 * (-3) = 8 - 6 = 2
The solutions are (5, 18) and (-3, 2).
Hope this helps!
