$3.90
You have to take $1.16 and multiply it by 2 so that you get the price for 4 pounds then divide 1.16 by 2. Then you have to add together the totals and you'll get the price for 5 pounds.
Or
You could take $1.16 divide it by 2 to get the unit price then multiply (or add it together 5 times) it by 5 to get a total of $3.90
Ronaldo's age = 13
after 5 years, his age = 13+5 = 18 years
After 5 years, Marissa's age = 18 * 2/3 = 12 years
Present age of marissa = 12 - 5 = 7 years
in 3 years, marissa's age = 7 + 3 = 10 years
Marissa will be 10 years old in 3 years.

The answer is D. All you have to do is graph the equation, and you will have the vertex and the roots. By the way, you can rule out B and C because those two do not follow the rules of a quadratic. Also, A and B have the wrong axis of symmetry, because the rocket lands after 10 seconds.
Hi there!
The general formula to find the perimeter of a rectangle is :
P = (Length × 2) + (Width × 2)
Let's say the width of the rectangle is "x".
The lenght of the rectangle is equal to 2x + 4.2
Replace everything you know in the formula :
42.6 = ((2x + 4.2) × 2) + ((x) × 2)
Simplify everything :
2x × 2 = 4x
4.2 × 2 = 8.4
x × 2 = 2x
42.6 = 4x + 8.4 + 2x
42.6 = 6x + 8.4
Isolate "x":
42.6 = 6x + 8.4
Subtract 8.4 from each side of the equation
34.2 = 6x
Divide each side of the equation by 6
5.7 = x
5.7cm = the width of the rectangle
Since the lenght of the rectangle is equal to 2 times the width of the rectangle plus 4.2 :
Length = (2 × 5.7) + 4.2
Length = 15.6cm
42.6 = (2 × 15.6) + (2 × 5.7) ? → YES
There you go! I really hope this helped, if there's anything just let me know! :)
