Answer:
Cost of 1 = 30
So cost of 8kg apples=8*30
=240
Step-by-step explanation:
By the additive property of equality, the equations John wrote are equivalent.
<h3>Additive property of equality: Determining equivalent equations</h3>
From the question, we are to determine if the equations John wrote are equivalent.
From the given information,
John wrote that
5 + 5 = 10
Then,
He added n to both sides of the equation to get
5 + 5 + n = 10 + n
From the Additive property of equality, we have that
"<em>If we add or subtract the same number to both sides of an equation, the sides remain equal</em>."
Since, John added the same number, n, to both sides of the equation, the equations John wrote are equivalent.

Step-by-step explanation:
They all liked one type of food.
Answer:
you can order 6 toppings.
Step-by-step explanation:
20-12.95= 7.05
1.50*4= 6.00
leaving 1.05 left as a Remainder.
Axis of symmetry = x = -b/2a
where y = ax² + bx + c
f(x) = x² + 6x - 1 ⇒ a = 1 ; b = 6 ; c = -1
x = -(6)/2(1) = -6/2 = -3
g(x) = -x² + 2 ⇒ a = -1 ; b = 0 ; c = 2
x = -0/2(-1) = 0/-2 = 0
h(x) = 2x² - 4x + 3 ⇒ a = 2 ; b = -4 ; c = 3
x = -(-4)/2(2) = 4/4 = 1
least : f(x) = x² + 6x - 1 ; axis of symmetry is -3
middle : g(x) = -x² + 2 ; axis of symmetry is 0
greatest : h(x) = 2x² - 4x + 3 ; axis of symmetry is 1
