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

Jlenok [28]

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.

5.2

Flying against the wind, a jet travels 1710 miles in 3 hours. Flying with the wind, the same jet travels 3720 miles in 4 hours.

Rufina [12.5K]

Answer:

Rate of jet in still air = 750 mph

Rate of wind = 180 mph

Step-by-step explanation:

Let the rate of jet in still air = $u$ mph

Let the rate of air = $v$ mph

So, Rate of jet against the wind = $(u-v)$ mph

Rate of jet with the wind = $(u+v)$ mph

Formula for Speed/Rate is given as:

$Speed = Distance \times Time$

Distance traveled in 3 hours against the wind = 1710 miles

Distance traveled in 4 hours against the wind = 3720 miles

$u-v=\dfrac{1710}{3}\\\Rightarrow u-v=570..... (1)$

$u+v=\dfrac{3720}{4}\\\Rightarrow u+v=930......(2)$

Adding (1) and (2):

$2u=1500\\\Rightarrow u=750\ mph$

By equation (1):

$750 - v =570\\\Rightarrow v =180\ mph$

Rate of jet in still air = 750 mph

Rate of wind = 180 mph
