18 is 60% of 30. I know this because 10% of 30 is 3 and 3 * 6 is 18
Answer:
V = 2010.6193 ft3
Step-by-step explanation:
When solving system equations, we can use substitution method or elimination. Today I'm using substitution method.
First name the 2 equations.
3x + y = 3 (1)
x + y = 2 (2)
Now pick one equation and express one algebra in forms of the other.
From (2),
x = 2 - y (3)
Now substitute (3) into (1),
3(2-y) + y = 3
6 - 3y + y = 3
6 - 2y = 3
6 - 3 = 2y
y = 1.5
Now substitute y = 1.5 into (2)
x + 1. 5 = 2
x = 2 - 1.5
x = 0.5
Therefore the answer is x = 0.5 and y = 1.5
Answer:
<em>x = 24 </em>
Step-by-step explanation:
The corresponding sides of similar Δs are proportional.
ΔADE ~ ΔABC ⇒ 
= 
= 
AD = x + 8 ; DE = 8
AB = x ; BC = 6
= 
⇔ 8x = 6(x + 8) ⇒ <em>x = 24</em>
47 is 0.47 and 2/3 is 0.66
