The top t appears to be the hypotenuse of a right triangle with angle 14.5 degrees amd opposite side 6.

$\sin 14.5^\circ = \dfrac{6}{t}$

$t = \dfrac{6}{\sin 14.5} \approx 23.96 \textrm{ inches} \approx 24 \textrm{ in}$

Someone solve for X please ? Step by step

irina1246 [14]

Start by distributing the 7 to both terms on the left hand side, and the 5 to both terms on the right hand side.

7(x - 2) = 5(x + 4)
7x - 14 = 5x + 20

Now, to solve for x, start by isolating the variable as much as you can.
7x - 5x = 20 + 14
2x = 34

x = 17

Jack and Jim went biking. Jack biked for 5 1/3 hours with average speed 12 1/2 miles per hour. Jim traveled exactly 1 1/5 as far

ahrayia [7]

Given that Jack biked for $5 \frac{1}{3}$ hours with an average speed of $12 \frac{1}{2}$ miles per hour.

The distance travelled by Jack is given by

$d=speed\times time \\ \\ =12 \frac{1}{2}\times5 \frac{1}{3}= \frac{25}{2} \times \frac{16}{3} \\ \\ = \frac{200}{3} =66 \frac{2}{3} \ miles$

Given that Jim travelled exactly $1 \frac{1}{5}$ as far as Jack did, then the distance Jim travelled is given by

$d=1 \frac{1}{5} \times66 \frac{2}{3} \\ \\ = \frac{6}{5} \times \frac{200}{3} =80$

Therefore, the length of Jim's journey is 80 miles.
