Answer:
10 songs
Step-by-step explanation:
20 + 1x = 3x
20 = 2x
10 = x
—
20 + 1(10) = 3(10)
20 + 10 = 30
30 = 30
.09:
"of" means that you have to multiply.
1/10 is equal to .1
If you multiply 0.1 by 0.9 you will get .09
Answer:Complementary angles are two angles whose degree measurements add up to 90 degrees. The first angle would be (x + 14.4) and its complementary angle would be x. Therefore, you would set up this problem as: x + (x + 14.4) = 902x + 14.4 = 902x = 75.6 x = 37.8 (one angle)And (x + 14.4) = 52.2 (other angle).
To check: 37.8 + 52.2 = 90
Step-by-step explanation:
I think the answer will be (-4,3)
