Answer:

14°

Step-by-step explanation:

(7x-1)°+(6x-1)°=180°(sum of angles in a straight line/being linear pair)

or,7x-1°+6x-1°=180°

or,13x-2°=180°

or,13x=182°

or,x=182°/13

or,x=14°

Pepsi [2]

Answer:

<h2>52% were jelly beans!</h2>

Explanation:

Cross multiply the following:

$\frac{x}{100} = \frac{71.76}{138}$

x times 138 = 138x

100 times 71.76 = 7,176

Divide both sides by 138:

$\frac{138x}{138} = \frac{7176}{138}$

780, or C, is correct. Since 9.75 is 1/80th of the actual measurement, we can set up an equation like this:

9.75 = 1/80x

Then multiply each side by 80:

780 = x

The actual building's height is 780 ft.

We can check this answer by plugging in 780 for x in the original equation:

9.75 = 1/80(780)

9.75 = 9.75
