5x - 3 = 7
<em><u>Add 3 to both sides.</u></em>
5x = 10
<em><u>Divide both sides by 5.</u></em>
x = 2
The value of x is 2.
 
        
             
        
        
        
Total = Principal * (1 + rate) ^ year
Total = 22,000 * (1.054)^1 = 23,188.00
Total = 14,000 * (1.054)^1 = 14,756.00
23,188.00 - 22,000 = 1,188.00 interest
14,756.00 - 14,000 = 756.00 interest
So the 22,000 earns (1,188.00 -756.00) = 432.00 more dollars in interest than the 14,000 dollars earns in interest.
 
        
             
        
        
        
50% of 1,678.89 = 839.445
10% = 167.889
5% = 83.9445
1% = 16.7889
.5% = 8.39445
Therefore 66% = 1108.0674
and 7.5% = 125.91675
So the two added together is: 1233.98415
To get the percentages simply do the following
50% = divide by two
10% = divide 50% by five OR divide the original number by 10
5% = divide 10% by two or divide 50% by 10
1% = divide 5% by 5 or divide original by 100
.5% = divide 1% by two
        
             
        
        
        
Answer:
do you mean in simplest form
if so then it is 2:3
if not then 6
Step-by-step explanation:
 
        
             
        
        
        
2/5 tablespoons of vanilla extract ... 6 muffins
x tablespoons of vanilla extract = ? ... 18 muffins
If you would like to know how much vanilla extract does he need, you can calculate this using the following steps:
x * 6 = 18 * 2/5
x * 6 = 36/5    /6
x = 36/5 / 6
x = 6/5 = 1 1/5
Result: Arthur will need 1 1/5 tablespoons of vanilla extract for 18 muffins.
