Answer:
5 weeks
Step-by-step explanation:
John deposits $5 per week and has $10, so his equation is 5x + 10.
Jasmine's equation is 3x + 20.
Make them equal to each other and solve for x:
5x + 10 = 3x + 20
Subtract 10 from each side
5x = 3x + 10
Subtract 3x from each side
2x = 10
Divide each side by 2
x = 5

Definition
A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit).
Example
Stem "1" Leaf "5" means 15
Total are:
9 + 
11 + 
23 + 29 +
47 + 
55 + 57 + 57 + 59 + 
65 + 65 + 66 + 66 + 67 + 68 + 69
70 + 71
= 954
 
        
             
        
        
        
Answer:
1875L = 1.875x10^6 mL
multiply by density to get 2.14x10^6
multiply by percentage to get 6.63x10^4 g of NaCl (66.3 kg)

Let
n-------> the number of nickels
q------> the number of quarters
we know that

so
 ----> equation A
 ----> equation A
 ----> equation B
 ----> equation B
substitute equation B in equation A
![0.05n+0.25[3n]=1.60](https://tex.z-dn.net/?f=0.05n%2B0.25%5B3n%5D%3D1.60)



Find the value of q

therefore
<u>The answer part a) is</u>
the number of nickels are   and the number of quarters are
  and the number of quarters are 
<u>the answer Part b) is</u>
The expressions that represents the number of quarters is
 
 
 
        
                    
             
        
        
        
A pythagoras triplet is a set of three numbers ... not just any three numbers,
but a set where the (square of one of them) is the sum of the (squares of the 
other two).  
If they're related in that way, then they can be the lengths of the sides of a 
right triangle.
If they're not, then they can't.
