Answer:
x=6 is not a solution 
Step-by-step explanation:
We can substitute 6 as x to find out: 
5(6-3)=6+13 
first, because of PEMDAS we'll do 6-3 
5(3)=6+13
multiply 5 by 3 and add 6 and 13 
15=19 
Since the statement is not true, that means that x=6 is not a solution 
Hope this helps!
 
        
             
        
        
        
You can see that an odd number of steps is simply multiplying the number of steps by a number that moves up one each time. For instance, 1*1, 3*2, 5*3, etc. It's a bit harder with the even numbers. Their pattern is multiplying half the number of steps by 1.5, but the ones place value moves up a number each time, for example, 2*1.5, 4*2.5, 6*3.5. This means that 10 steps is 10 * 5.5, or 55 blocks and that 100 is 5,050 steps.
 
        
             
        
        
        
For this case we have the following amount of liquid:
 2.5 oz.
 The amount of liquid needed is:
 3 oz.
 Therefore, the amount of fluid needed is:
 3oz - 2.5oz = 0.5oz
 Answer:
 b. no, hildy did not get a reasonable amount of liquid because she only needed 0.5 oz (3 - 2.5 = 0.5).
        
                    
             
        
        
        
20  because when you do it that way when it is behind the decimal the numbers are always the opposite thousand hundred tens ones . tens hundreds thousands
        
             
        
        
        
Answer:
<u>Hanna is 8 years old.</u>
Step-by-step explanation:
Hanna = x
Tina = 4x
Sum = 40.
Hanna =?
Hanna + Tina = 40
4x + x = 40
5x = 40
x = 40/5
x = <u>8</u>.
Hanna is <u>8 years</u> old.
