Answer:

Step-by-step explanation:

8² = 30 * 43x

x = 8² / 30 * 43 = 8* 8 / 30*43

 = 2*2*2 * 2*2*2 / 3*2*5*43

=2*2*2*2*2/ 3*5*43

= 32/645

5 1/2 +1 3/10x=13 what does x equal
Advocard [28]

Answer:

x=5\frac{10}{13}

Explanation:

Given the equation

5\frac{1}{2}+1\frac{3}{10}x=13

Step 1: Change all the mixed fraction to improper fractions

\implies\frac{11}{2}+\frac{13x}{10}=13

Step 2: Find the lowest common multiple of the denominators (2 and 10)

The lowest common multiple = 10

Step 3: Multiply all through by 10.

\begin{gathered} \implies\frac{11}{2}\times10+\frac{13x\times10}{10}=13\times10 \\ =55+13x=130 \end{gathered}

Step 4: Apply the subtraction law of equality. (Subtract 55)

\begin{gathered} 55-55+13x=130-55 \\ 13x=75 \end{gathered}

Step 5: Apply the division law of equality. (Divide by 13)

\begin{gathered} \frac{13x}{13}=\frac{75}{13} \\ x=5\frac{10}{13} \end{gathered}
