Answer:

x = 14 and 2/3

Step-by-step explanation:

Make an equation where x is the number.

2x - 15 = 7 + 1/2x

Then, solve the equation.

multiply both sides by 2 to get rid of the fraction

4x - 30 = 14 + x

subtract x from both sides

3x - 30 = 14

add 30 to both sides

3x = 44

divide both sides by 3

x = 14 and 2/3

Complete the sentence. 0.05 is 1/10 the value of __?

Alja [10]

To find the answer, multiply the decimal by 10. 0.05 X 10 = 0.5, and since 0.05 goes into 0.5 10 times, it is equivalent to 1/10th of 0.5.

What is the inverse of function f? f(x)=10/9r+11

Rasek [7]

$f(x) = \frac{10}{9}x + 11 \\$

So :

$y = \frac{10}{9}x + 11 \\$

Subtract the sides of the equation minus 11

$y - 11 = \frac{10}{9}x \\$

Multiply the sides of the equation by 9

$9(y - 11) = 10x$

$9y - 99 = 10x$

Divided the sides of the equation by 10

$\frac{9y - 99}{10} = x \\$

So :

${f}^{ - 1}(x) = \frac{9x - 99}{10} \\$
