Answer:
D
Step-by-step explanation:
The missing step is to perform the inverse of a square root by squaring both sides of the equation. This means to multiply 18*18=324 and the square root expression leaving just the inside untouched. The correct step is D.

Answer:
The cost of 1 orange y = 1.1
Step-by-step explanation:
Let cost of 1 apple = x
Cost of 1 orange = y
We will make equations from given statements to find the cost of 1 orange i.e y
Wilma bought 3 apples and 6 oranges for $9: Mathematical expression will be:
Fernando bought 6 apples and 2 oranges for $7. Mathematical expression will be:
Let:
Multiply eq(1) by 2 and subtract both equations.
So, We get value of y=1.1
Now, put value of y in eq(1) to find value of x
So, the cost of 1 orange y = 1.1
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
