198 + (199*3) + (200*2) +(201*5) + (202*2) = 2604

frequency = 1 + 3 +2 + 5 + 2 = 13

201 = (2604 + x )/14
multiply both sides by 14
x = 201*14 = 2604 +x

x = 2814 = 2604 +x

subtract 2604 from both sides:

x = 2814 - 2604
x = 210 cm

A scientist has saline solutions with concentrations of 4% and 14% . He wants to mix some of each solution to get 65 milliliters

Komok [63]

Let volume of 4% solution = x and of 14% be y

them x + y = 65........(1) also using the actual weights of salt:-

0.04x + 0.14y = 65*0.06 = 3.9

multiplying the above equation by -25 we have

-x - 3.5y = -97.5 adding this to equation (1)

--2.5y = -32.5
y= 13

and x = 65 - 13 = 52

so we need 13 mls of the 14%, and 52 mls of the 4% solution.

Slove for x: x+1/3=1/4

lana [24]

Hey!

To solve this problem, we must subtract one over three from both sides of the equation. This will give us x on its own.

Original Equation :
$x + \frac{1}{3} = \frac{1}{4}$

New Equation {Added Subtract $\frac{1}{3}$ to Both Sides} :
$x + \frac{1}{3} - \frac{1}{3} = \frac{1}{4} - \frac{1}{3}$

Solution {New Equation Solved} :
$x=- \frac{1}{12}$

So, this means that in the equation provided, $x=- \frac{1}{12}$ .

Hope this helps!
