Solve the equation. x/3 + 12 = 18

djyliett [7]

<u>answer:</u> $x = 18$

$\frac{1}{3}x + 12 = 18$ | subtract 12 on both sides, and solve.

$\frac{1}{3}x = 6$ | divide by $\frac{1}{3}$ on both sides, and solve.

$x = 18$ | final answer.

hope this helps! ❤ from peachimin

A book sold 41,900 copies in its first month of release. Suppose this represents 8.1 percent of copies sold to date. How many co

Diano4ka-milaya [45]

The total number of copies that have been sold till date are: 517284

Step-by-step explanation:

Let x be the total number of copies sold

Then

41900 is 801 percent of x

This can be mathematically written as

$41900 = 8.1\%\ of\ x\\41900 = 0.081 * x\\x = \frac{41900}{0.081}\\x = 51728.9$

Rounding off to nearest whole number

517284

Hence,

The total number of copies that have been sold till date are: 517284
