47x-12
by step
36x -12 +11
3s+28=85, take away 28 from both sides of the equals to give you 3s=57, divide by 3 on both side to give you s=19.
Answer:
2.50x+1.75y<=200
Step-by-step explanation:
Consider the data
Total amount of money available $200
Cost of cedar is $2.50 per feet. The the cost of pine $1.75 per feet
x=# of feet of cedar brought
y=# of feet of pine brought
As the cost of cedar wood is $2.50 and x is the # of feet of cedar brought, so the total cost of # of the wood is $2.50x
As the cost of pine is $1.75 and y is the # of feet of pine brought, so the total cost of # of the wood is $1.75y
The total cost of the # of cedar and pine woods together is
$2.50x+$1.75y
And the total amount available is 200, and it doesn't exceed so
$2.50x+$1.75y<= 200
Answer: The answer is $20
Multiply 400 by .05 or 5%.
