Your answer is incorrect because X is a common said term, right? It’s obviously a variable, and it’s a constant. But an expression is like the entire problem or math expression you know what I’m saying?

It's not an expression, an expression, is like, the entire equation.

1/4 foot every 3/4 hour how many feet in one hour

RUDIKE [14]

For this case we propose a rule of three:

$\frac {1} {4}$ foot -------------> $\frac {3} {4}$ hour

x -----------------------------------> 1 hour

Where "x" represents the amount of foot in one hour.

$x = \frac {1 * \frac {1} {4}} {\frac {3} {4}}\\x = \frac {\frac {1} {4}} {\frac {3} {4}}\\x = \frac {4 * 1} {3 * 4}\\x = \frac {4} {12}\\x = \frac {1} {3}$

So, we have $\frac {1} {3}$ foot every hour.

Answer:

$\frac {1} {3}$ foot every hour

One exterior angle of a regular pentagon has a measure of (2x)”. What is the value of x?

USPshnik [31]

Answer:

x = 36°

Step-by-step explanation:

The sum of the exterior angles of a pentagon is always 360°. Since the pentagon is regular, meaning that all of its sides and interior angles are congruent, we know that all of the exterior angles are also congruent. Since a pentagon has 5 sides, we know that there are 5 congruent exterior angles, therefore:

5 * 2x = 360

10x = 360

x = 36°

Rewrite the expression with a rational exponent as a radical expression.

Nuetrik [128]

Answer:

Rewriting the expression $(3^\frac{2}{3})^\frac{1}{6}$ with a rational exponent as a radical expression we get $\mathbf{\sqrt[9]{3} }$
