Answer:
x = 200
Step-by-step explanation:
Given
x - y = 30 ← substitute y = 15 into the equation
x - × 15 = 30 , that is
x - 10 = 30 ( add 10 to both sides )
x = 40 ( multiply both sides by 5 to clear the fraction )
x = 200
Answer:
Cost y is directly proportional to the pound of potato y = 1.89x The constant of proportionality is the cost of 1 pound of potato, and it is 1.89
Step-by-step explanation:
I believe that the equation has X to the 2 power meaning that the answer for X is...
X= 10, and -10
The answers are x+1=4, -5+x=-2, and 2+x=5. The x equals 3.
