Answer:
Sue is 6 and Mary is 10
Step-by-step explanation:
let Sue's age be x then Mary is x + 4 and the sum of their ages is
x + x + 4 = 16
2x + 4 = 16 ( subtract 4 from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
x + 4 = 6 + 4 = 10
then Mary is 10 and Sue is 6

Hi there!
Your answer is:
Domino's waits to reveal the price until the end because, psychologically, you're predisposed to put & LEAVE more toppings on your pizza. If you see how each topping affects the price of the pizza each time you add one, you may limit the amount you choose. If you wait until the end to see it, by that point you think "Well I <em>need</em> these toppings on there to make it delicious." From a business standpoint, it's more financially beneficial to use the "hide the price until the end" system. However, from a consumer standpoint, most prefer seeing a live breakdown of how each topping affects the price so we can limit what we pay to a reasonable amount.
I hope this helps!
I would graph the points and find the equation
A= 3
b= 4
=3.14(a^2 + ab)
substitute the given a & b values in expression
=3.14((3)^2 + (3*4))
multiply inside parentheses
=3.14(9 + 12)
add inside parentheses
=3.14(21)
multiply
=65.94
ANSWER: 65.94
Hope this helps! :)
