Chapter 2

Solve. $$ 0.127 x-2.685=0.027 x-2.38 $$

Fill in the blank with a number of your choice so that each equation has the given solution. ______ \(x=10 ;\) solution: \(\frac{1}{2}\)

Substitute the given values into each given formula and solve for the unknown variable. If necessary, round to one decimal place. $$ V=\frac{1}{3} \pi r^{2} h ; \quad V=565.2, r=6 $$

The equation \(6 x+2-2 x=4 x+1\) has no solution. Try solving this equation for \(x\) and describe what happens.

Solve. 0.07 x-5.06=-4.92

Solve. 0.06 y+2.63=2.5562

Solve. See Examples 1 through 7 $$ x+\frac{5}{4}=\frac{3}{4} x $$
