-7/12=y/-36
times both sides by -36 (-36=12*-3)
-3*-7=y
21=y
y=-21

7x-2=12x-22
-2=5x-22
20=5x
x=4
7×4-2=26 (12×4-22=26)
(2x+11)×2=8x-14
4x+22=8x-14
22=4x-14
36=4x
x=9
( (2×9+11)×2=58. 8×9-14=58. so it's correct)
(3x+5)+(9x-17)=180
12x-12=180
12x=192
x=16
( (3×16+5)+(9×16-17)=53+127=180 so it's correct)
10x-27=2x+29
8x-27=29
8x=56
x=7
10×7-27=43 (2×7+29=43)
V=180-43°=137°
Answer:
x = 3.46 units
Step-by-step explanation:
Given:
angle RQS = 60
QS = 2 units
PS = 8 units
To Find:
RS = x = ?
Solution:
In triangle QRS,
tan angle Q = RS / QS
tan 60 = x / 2
root 3 = x / 2
x = 2 root 3
x = 2 x 1.73
Therefore, x = 3.46 units

The median of the numbers would be 7.5
One cat has four paws, so there are 120/4=30 cats. If a "set" of cats is two uncool cats and three cool cats, there are five cats in a set, so there are 30/5=6 sets. Since each of the six sets contains three cool cats, there are 18 cool cats in the family.
