It would take 4.44 minutes to fill the sink using both faucets P and faucet Q together
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let t represent the time it takes to fill the sink using both faucets together, hence:
(1/10 + 1/8)t = 1
t = 4.44 minutes
It would take 4.44 minutes to fill the sink using both faucets P and faucet Q together

Armans age : x
Aregs age: y
X = 5y
(15 - 12) = y. They said narek is 12 years older than areg so you deduct 12 years from nareks age which is 15.
So therefore y = 3. So Areg is 3 years old.
Since we know that y = 3
X = 5(3)
X = 15
So therefore Arman is 15 years and Areg is 3 years.
Answer:
<em><u>D. x≥3 </u></em>
Step-by-step explanation:
☜☆☞ given equation..... 3x-1 ≥ 8
<em>–</em><em>»</em><em> </em><em>3x ≥ 8+1</em><em> </em>
<em>–</em><em>»</em><em> </em><em>3x ≥ 9 </em>
<em>–</em><em>»</em><em> </em><em> </em><em>x ≥ 9÷3</em>
<em>–</em><em>»</em><em> </em><em> </em><em>x ≥ 3</em>
