Given ; 2(10-13x)+9x=-34x+60

rewona [7]

Try comparing your solution with the following:

Solution:

$2(10-13x)+9x=-34x+60\\(20-26x)+9x=-34x+60\\20-26x+9x=-34x+60\\20-17x=-34x+60\\20-60=-34x+17x\\-40=-17x\\x=\frac{40}{17}$

Answer:

$x=\frac{40}{17}$

Check:

$2[10-13(\frac{40}{17})]+9(\frac{40}{17})=-34(\frac{40}{17})+60\\-20=-20$

nevsk [136]

In the morning
(3/4) (strawberries / minutes) * (60/1) (minutes / hours) = 45 (strawberries / hours)
in the afternoon
(2/3) (strawberries / minutes) * (60/1) (minutes / hours) = (40 strawberries / hours)
the difference between your morning and afternoon packing rates, in pints per hour is
45-40 = 5 (strawberries / hours)

A person gets on a Ferris wheel at the starting point. The starting point is 15 feet off the ground. The Ferris wheel has a radi

lisov135 [29]

<h2>Answer:</h2>

$\boxed{\frac{25}{2}(\sqrt{6}+\sqrt{2})+65}$

<h2>Explanation:</h2>

The height of the rider from the ground after the Ferris wheel equals the starting point is 15 feet off the ground plus the radius of the Ferris wheel plus the opposite side of the triangle ΔABC (See figure below). Hence our goal is to find this side. We have the angle $11\pi /2=165^{\circ}$ , therefore the angle ∠BAC = 165° - 90° = 75°. So this side can be found using trigonometry:
