You have to cross multiply (multiply the numerator of the first by the denominator of the second and the numerator of the second by the denominator of the first).

$\frac{x+4}{3} = \frac{4}{10}$

$10x+40=12$

$10x = -28$

$x=-2.8$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[21]

$\frac{4}{n+8} = \frac{10}{8}$

$32 = 8n + 64$

$8n = -32$

$n=-4$

Find the area of a trapezoid with bases 2ft and 3ft and height 1/3 foot. Round your answer to the nearest tenth

amid [387]

Answer:

Area = 5/6 of a foot^2

Step-by-step explanation:

Formula

Area of a trapezoid (formula) = 1/2 (b1 + b2)*h/2

Givens

b1 = 2 feet
b2 = 3 feet
h = 1/3 foot

Solution

Area = 1/2(2 + 3)*1/3

Area = 1/2(5)* 1/3

Area = (1/2 * 1/3) * 5

Area = (1/6) * 5

Area = 5/6
