The answer too your question is 100
Find the greatest common factor (GCF) of 9 and 12 using factor trees. The GCF is 3
Divide each term (9 and 12) over 3
9/3 = 3
12/3 = 4
So 9/12 reduces to 3/4
In other words, 9/12 = 3/4
--------------------------------------
Now focusing on 3/4, we can multiply top and bottom by the same value. Let's say we multiply top and bottom by 5
3*5 = 15
4*5 = 20
So 3/4 = 15/20
--------------------------------------
So two ratios equivalent to 9/12 are 3/4 and 15/20. There are infinitely other ratios that are equivalent.
In short, the answers are 3/4 and 15/20.
Let's use the variable "r" to represent the investment rate of the stocks:
2r(500) + r(800) = 45
1000r + 800r = 45
1800r = 45
r = 0.025
2r = 0.05
The $500 is invested at 5%
Answer: it cost $50.94 to fill an 18 gallon tank.
Step-by-step explanation:
Julio filled his gas tank with 6 gallons of premium unleaded gas for $16.98. This means that amount it cost to will fill his gas tank with 1 gallon of premium unleaded gas would be
16.98/6 = $2.83 per gallon
Therefore, the amount of will cost to an 18 gallon tank with premium unleaded gas would be
18 × 2.83 = $50.94
