Answer:
1/2 (150 -2x)
Step-by-step explanation:
You know queen parallela has 150 meters to build her pen. That means that the perimeter of the pen must be 150 (meters), therefore if x is the width and L is the lenght, we have
2*x + 2*L = 150
We want the value of L in terms of x, so we will send 2*x to the other side of the equation and we have
2*L = 150 - 2*x
Therefore
L = (150-2*x)*1/2
The correct answer is 1/2 (150 -2x)
I hope this helped you!
Answer:
12 toppings
Step-by-step explanation:
There's a 60 cent difference in the base price, and the price of toppings is a 5 cent difference, so it would take 60/5 or 12 toppings to make up the difference. r, you can make a chart. Or you can do algebra and solve an equation:
6.75 + .75 x = 6.15 + .8x where x is the number of toppings. Subtract 6.15 from both sides.
.60 + .75x = .8 x Subtract .75x from both sides
.60 = .05x Divide both sides by .05
