Question

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

Answer 1

5.2

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 * ((17)/(13)) = ((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

5.2

Explanation:

`(17)/(13) = (x)/(4)`

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

`((4)/(1))((17)/(13)) = x`

Multiply the numerators and the denominators separately.

4 • 17 = 68

1 • 13 = 13

`(68)/(13) = x`

Divide.

68 ÷ 13 = 5.23

Round to the nearest tenth.
