Find the GCF of 45, 90, 75: which is 15
So he can make 15 stones total.
Divide each of the color numbers by 15 to get the number of tiles he uses in each stone
        
                    
             
        
        
        
Answer:
 .
.
Step-by-step explanation:
It is given that Wendy's mother recorded how many donuts she has eaten over the past few months.
Jelly-filled donuts = 6
Maple donuts = 53  
Glazed donuts = 11  
Powdered sugar donuts = 5
Now,
Total number of donuts = 6 + 53 + 11 + 5 = 75
We need to find the experimental probability that the next donut Wendy eats will be a powdered sugar donut.

Answer:
37.4
Step-by-step explanation:
a = 4 and b = 8
change the equation
5.4 + (4) (8)
use P.E.M.D.A.S. and multiply
4*8 = 32
add
5.4 + 32 = 37.4
 
        
             
        
        
        
Answer:
Jim's current weight = 119 pounds
Step-by-step explanation:
1 Stone = 14 pounds
 stone = 1.5 stone
 stone = 1.5 stone
1.5 stone = 1.5 (14 pounds) = 21 pounds
Jim lost 21 pounds
Let X be Jim's Original Weight
Y be his present weight
As per given statement in the Question:
After losing 1.5 stones (21 pounds of weight) Jim now weighs Y 
Present weight = original weight - 21 
Y = X -21     <u>                                                    Equation 1</u>
Also Current Weight = 85 % (Original weight) 
Y = 85 % (X) =
Y=
put in Equation 1
 = X-21
 = X-21
85X = (X-21) 100
85 X = 100 X -2100
or
2100 = 100 X - 85X
2100 = 15X 
or 
15 X = 2100

X= 140 pounds ( Original Weight)
Current Weight = Y = Original weight - 21 <u><em>(From Equation 1)</em></u>
Y = X -21
Y = 140 -21
Y = 119 pounds (Current Weight)

no need for distance formula
same x, only need to subtract y
