Questionc0.2+0.9=3.9\frac{c}{0.2}+0.9=3.9

Studdy Solution

STEP 1

1. The equation c0.2+0.9=3.9\frac{c}{0.2} + 0.9 = 3.9 is a linear equation in terms of cc.
2. We will solve for cc by isolating it on one side of the equation.

STEP 2

1. Isolate the term c0.2\frac{c}{0.2}.
2. Solve for cc.

STEP 3

Subtract 0.90.9 from both sides of the equation to isolate the term c0.2\frac{c}{0.2}:
c0.2+0.9=3.9\frac{c}{0.2} + 0.9 = 3.9 c0.2=3.90.9\frac{c}{0.2} = 3.9 - 0.9 c0.2=3.0\frac{c}{0.2} = 3.0

STEP 4

Multiply both sides of the equation by 0.20.2 to solve for cc:
c0.2=3.0\frac{c}{0.2} = 3.0 c=3.0×0.2c = 3.0 \times 0.2 c=0.6c = 0.6
The value of cc is:
0.6\boxed{0.6}
