Question

Help please ! solve for x and round the answer to the nearest tenth. need it asap , thank you

Answer 1

Answer:

5.2

Step-by-step explanation:

Note the equal sign. This means that these two fractions are proportional. First, find common denominators. Note that what you do to the denominator, you do to the numerator:

$4 * 13 * (\frac{17}{13}) = (\frac{x}{4}) * 4 * 13\\\\4 * 17 = x * 13\\\\68 = x * 13$

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 13 from both sides:

$68 = x * 13\\\\(68)/13 = (x * 13)/13\\x = 68/13\\x = 5.2$(rounded to the nearest tenth).

5.2 is your answer.

Answer 2

Answer:

5.2

Step-by-step explanation:

$\frac{17}{13} = \frac{x}{4}$

To solve for x, we want to isolate x. To do this, we need to multiply both sides by 4.

$(\frac{4}{1})(\frac{17}{13}) = x$

Multiply the numerators and the denominators separately.

4 • 17 = 68

1 • 13 = 13

$\frac{68}{13} = x$

Divide.

68 ÷ 13 = 5.23

Round to the nearest tenth.
