For 25, I would begin with working out the difference in price.
$450 - $360 = $90
Then, $450 is 100% of the cost, therefore we want to know how much it has decreased.
I would work out 1% of $450. [$450 / 100 = $4.50]
Now if we divide $90 (the change in cost) by $4.50, we can tell what percent of a decrease we have.
90 / 4.5 = 20
Therefore we have a 20% decrease.
Answer: A. 30+(-12)+70
Step-by-step explanation:
Commutative property of addition is given by : a+b = b+a , where a and b can be any expression of real numbers.
It basically changes the order of the so that simplification of any expression becomes easier.
In A. we use this property as
30+(-12)+70 = 30+[(-12)+70]
= 30 + [70+(-12)] [we switched order of (-12) and 17]
= 30+70-12
= 100-12
= 88
The rest of the expression already arranged accordingly, there is no need to apply commutative property to change the order of the numbers.
So the correct option is A. 30+(-12)+70.
Answer: 
<u>Step-by-step explanation:</u>
Use the Slope formula: 
and the Point-Slope formula: y - y₁ = m(x - x₁)
a) (-2, 0) and (3, 4)
Let (x₁, y₁) = (-2, 0)
y - y₁ = m(x - x₁)
b) m = 1/3 (x₁, y₁) = (2, 4)
y - y₁ = m(x - x₁)
Answer:
AC<AB+BC
If you were to flatten out the distance AB and BC, logically speaking, you'd get a larger distance than the distance AC.
