Solve 0.5*(7.2)^2=9.8x

$$0.5 \times ( 7.2 ) ^ { 2 } = 9.8 x$$

Solve for x

$$x = \frac{648}{245} = 2\frac{158}{245} \approx 2.644897959$$

Steps for Solving Linear Equation

Calculate 7.2 to the power of 2 and get 51.84.

$$0.5\times 51.84=9.8x$$

Multiply 0.5 and 51.84 to get 25.92.

$$25.92=9.8x$$

Swap sides so that all variable terms are on the left hand side.

$$9.8x=25.92$$

Divide both sides by 9.8.

$$x=\frac{25.92}{9.8}$$

Expand \frac{25.92}{9.8} by multiplying both numerator and the denominator by 100.

$$x=\frac{2592}{980}$$

Reduce the fraction \frac{2592}{980} to lowest terms by extracting and canceling out 4.

$$x=\frac{648}{245}$$
