X is the amount of distilled water that must be added (in milliliters)
2/(100+x)=9/(1000)
2000=900+9x
1100=9x
122.22=x
x= 122
The answer is 122 milliliters of distilled water must be added
The two tangent lines for each circle are the same length. Set the equations to equal and solve for x.
1. 4x + 3 = 3x +12
Subtract 3x from each side:
x +3 = 12
Subtract 3 from both sides:
x = 9
2. -2 + x = 2x -7
Subtract 2x from both sides:
-2 - x = -7
Add 2 to each side:
-x = -5
Multiply both sides by -1:
x = 5
A) Action: multiply both sides by 4.
Have a look:
(x/4)x4=16x4
x=64
As you can see, the value of x can be found by multiplying 4 on both sides.
Hope I helped :)
Answer:
21
Step-by-step explanation:
s=2
so, v=2+19
