two angles are conplementary angles. One angle measures 59 the other measures (4n-1) what is the value of n​
natulia [17]

Answer:

n = 8

Step-by-step explanation:

Complementary angles add up to 90°

So,

59° + (4n - 1) = 90°

4n - 1 = 90° - 59° = 31°

4n = 31° + 1° = 32°

4n° = 32°

n = 32 ÷ 4 = 8

Answer: 600

Step-by-step explanation:

Given : Sue planted 4 times as many apple seeds as she planted orange seeds. 15 percent of the apple seeds grew into trees, and 10 percent of the orange seeds grew into trees

Let x be the number of apply seeds and y be the number of orange seeds , the we have the following equations:-

x=4y           (1)

0.15x+0.10y=420            (2)

Put x= 4y in (2), we get

0.15(4y)+0.10y=420

0.60y+0.10y=420

0.70y=420

Divide both sides by 0.70.

y=600

Hence, Sue planted 600 orange seeds.
