Answer:
The answer to your question is: 32 x + 2y - 107
Step-by-step explanation:
Simplify 5+2{y-4[3x+7(2-x)]}
5 + 2 { y - 4[ 3x + 14 - 7x ]}
5 + 2 { y - 12x -56 +28x }
5 + 2y - 24 x - 112 + 56x like terms
32 x + 2y - 107
Answer: $217.
Step-by-step explanation:
So he starts with 28 dollars. We want to find out how much total he makes. To do so we multiply 21 by 9 because he sells 21 ornaments at $9. 21 x 9 = 189. 189 + 28 = 217. So with the $28 from the start, he made $217.
(58 mile/hour) x (5,280 feet/mile) x (1/3,600 hour/second) =
(58 x 5,280) / (3,600) feet/second =
85.1 fps (rounded)
The mechanical advantage is the ratio of the radii: 5/0.5=10.
Answer: $172.50
Step-by-step explanation: Method 1:
The original price of the item is $230.
The discount is 25%.
Let's find 25% of $230.
25% of $230 = 0.25 * $230 = $57.50
The discount amount is $57.50.
Now we subtract the amount of the discount from the original cost.
Sale price = $230 - $57.50 = $172.50
Method 2.
The original price is $230.
That means that $230 is 100% of the price since 100% of a thing means the entire thing.
Since the discount is 25% of the price, we subtract 25% from 100%, 100% - 25% = 75%.
The sale price is 75% of the original price.
Now we find 75% of $230.
75% of $230 = 0.75 * $230 = $172.50
