Let units cancel out just like numbers...
25365.4cm^3(2.7g/cm^3)=68486.58g which is 68486.6g (to nearest tenth)
<u>→ Chapter : Linear Equation of Two Variables ←</u>
<em><u>≡ We know that:</u></em>
↔ y = 4x + 6
⇔ 3x + y = 41
↔ y = 41 - 3x
<u><em>≡ Solution:</em></u>
<em>⇔ First, find the value of x:</em>
⇒ y = y
⇒ 4x + 6 = 41 - 3x
⇒ 4x + 3x = 41 - 6
⇒ 7x = 35
<u>⇒ x = 5</u>
<em>⇔ Then, find the value of y:</em>
⇒ y = 4x + 6
⇒ y = 4(5) + 6
⇒ y = 20 + 6
<u>⇒ y = 26</u>
<em>∴ So, the solution of that equation is (5, 26)</em>
Loga x=n ⇔a^n=x
Therefore:
log₄ (x+20)=3
3⁴=x+20
64=x+20
x=64-20
x=44
Answer: x=44
The answer is y=207 hope this helps
