Solve 4.5-1/2x(7.6-3.5)+2.3*4.05

$$4.5 - \frac { 1 } { 2 } x ( 7.6 - 3.5 ) + 2.3 \times 4.05$$

Evaluate

$$-\frac{41x}{20}+13.815$$

Solution Steps

Subtract 3.5 from 7.6 to get 4.1.

$$4.5-\frac{1}{2}x\times 4.1+2.3\times 4.05$$

Convert decimal number 4.1 to fraction \frac{41}{10}.

$$4.5-\frac{1}{2}x\times \frac{41}{10}+2.3\times 4.05$$

Multiply \frac{1}{2} times \frac{41}{10} by multiplying numerator times numerator and denominator times denominator.

$$4.5-\frac{1\times 41}{2\times 10}x+2.3\times 4.05$$

Do the multiplications in the fraction \frac{1\times 41}{2\times 10}.

$$4.5-\frac{41}{20}x+2.3\times 4.05$$

Multiply 2.3 and 4.05 to get 9.315.

$$4.5-\frac{41}{20}x+9.315$$

Add 4.5 and 9.315 to get 13.815.

$$13.815-\frac{41}{20}x$$

Expand

$$-\frac{41x}{20}+13.815$$
