Answer:

Step-by-step explanation:

Angles (2x + 14)° and (x + 7)° are complementary angles.

If two angles are complementary, then they add up to 90°.

Therefore we have the equation:

(2x + 14) + (x + 7) = 90 <em>combine like terms</em>

(2x + x) + (14 + 7) = 90

3x + 21 = 90 <em>subtract 21 from both sides</em>

3x = 69 <em>divide both sides by 3</em>

x = 23

There are 36 ribbons of which 1/5 are yellow, 7/15 are pink and the remaining ribbons are

Kay [80]

Step-by-step explanation:

Let there be x blue ribbons

$\therefore \: \frac{1}{5} + \frac{7}{15} + x = 36 \\ \therefore \: \frac{1 \times 3}{5 \times 3} + \frac{7}{15} + x = 36 \\ \therefore \: \frac{3}{15} + \frac{7}{15} + x = 36 \\ \therefore \: \frac{3 + 7}{15} + x = 36 \\ \therefore \: \frac{10}{15} + x = 36 \\ \therefore \: x = 36 - \frac{10}{15} \\ \therefore \: x = \frac{36 \times 15 - 10}{15} \\ \therefore \: x = \frac{540 - 10}{15} \\ \therefore \: x = \frac{530}{15} \\ \therefore \: x = 35\frac{5}{15} \\ \\ \therefore \: x = 35\frac{1}{3} \: are \: blue. \\$
