Answer:
A is the one with variables.
B=44°
Step-by-step explanation:
x+10+3x+x=180
5x= 180-10
x=34
B= 34+10
-28
2(-2) is -4 and -24+-4 is -28 so yeah
16
24/8=3
48/3=16
49.686 kg
Since the density of the air remains constant in the question
We can represent this equation as a ratio;
10 m³ = 13 kg
(4.2 * 3.5 * 2.6) m³ = ? (x) kg
4.2 * 3.5 * 2.6 = 38.22
We cross multiply
38.22 * 13 = 10 * x
X = 496.86 /10
X = 49.686
