just substitute 10 into the equation
10=2x-6
add 6 to both sides
16=2x
divide both sides by 2
x=8
Pizzas are circles. Area of circles is (pi)r^2.
Then find the cost per in.^2
Smallest cost per in.^2 is better buy.
Given the fraction 5/12 and 9/16, the least common denominator can be get by giving the possible common multiples of 12 and 16.
12 = 12, 24, 36, 48, 60, 72, 84, 96, 108, 120
16 = 16, 32, 48, 64, 80, 96, 112, 128, ...
So looking above, the common are 48 and 86 but the smallest is 48.
So the LCD is 48.
Answer:
The sale price of the item is $
255
Step-by-step explanation:
To determine the amount of discount (
d
) offered by the store, we calculate
15
% of the sale price. Thus:
d = 300 × 15
÷ 100
d = 3
00 × 15 ÷ 1
00 (take the 2 zeros out on both the hundred and 3 hundred)
d = 3 × 15
d = 45
If the amount of discount is known, the sale price (
s
) of the item will be the regular price minus the discount. Hence:
s = 300 − 45
s = 255
Hope this helps you! If not sorry!
