Answer:
x = 1.2375 or 99/90
Step-by-step explanation:
<u>Step 1:  Distribute</u>
21 + 40(2x - 3)
21 + 80x - 120
<u>Step 2:  Combine like terms</u>
21 + 80x - 120
80x - 99
<u>Step 3:  Solve for x</u>
80x - 99 + 99 = 0 + 99
80x / 80 = 99 / 80
x = 1.2375
Answer:  x = 1.2375 or 99/80
 
        
                    
             
        
        
        
Answer:
6
Step-by-step explanation:
Question tests the ability to get quotient
Here, 32 ft is divided by 5’3” 
Normally, ft is denoted by ' while inches is denoted by ". So we divide 32 ft by 5ft and 3 inches
First, we convert dimensions into similar units. To convert 5’3” to ft, we divide 3” by 12 hence 3÷12=0.25'
The total is now 5.25'
Now
32'÷5.25'=6.1538461538461
This means, we shall obtain 6 whole pieces with some remainder. Since the question needs the whole pieces only, then the answer is 6
 
        
             
        
        
        
Answer:
9572 visitors
Step-by-step explanation:
This is exponential: y=ab
a = initial value
b = growth rate
It will grow by 5% each year but also keep the same amount as last year (100% of last year's visitors)
a = 7500
b = 1.05

Plug in x=5
9572.111719 = 9572 visitors
 
        
             
        
        
        
You have 3 coins and you want 2 get heads, so you make the 2 and 3 a probability and you get 2/3
        
             
        
        
        
<u>(2 x y) </u>is a factor of (6 x y), so it's the highest common factor of both expressions.
