Answer:
-19.8
Step-by-step explanation:
-3 x 6 = -18
-0.3 x 6 = -1.8
add together: -18 + -1.8 = -19.8
1, 6, 15, 20, 15, 6, 1
the price for one pretzel was $1.75
d for drinks
p for pretzel
3d + 3p = 9
3d = 9 -3p
d = 3 - p
replace d = 3 - 9 into 4d + 2p = 8.5
4d + 2p = 8.5
4(3 - p) + 2p = 8.5
12 - 4p + 2p = 8.5
-2p = 8.5 - 12
-2p = -3.5
p = 1.75
60°
Complementary angles both add up to 90°. Therefore if one angle is twice the other, then if we divide 90 by 3 then we get 30. Two parts of 30 is 60 plus the other 30 and we get 90. The individual angle is 60°and the other is 30°
The natural numbers from 1 to 30:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30.
The prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29.
