Answer:
25% discount
Step-by-step explanation:
48*2=96
However, instead one pair is 50% off. So, one pair will be $48 and another will be $24. So, if you purchase two pairs, you only have to pay$72. 72/96=.75. This means you are paying for 75% of the original price, meaning you got 25% off discount.
15x-6
21x/2+3. Multiply everything by 2: 30x-12=21x+6. Combine like terms: 9x=18. Get the unknown by itself: 9x/9=X. 18/9=2. X is less than or equal to 2 :)
The answer should be c. 144
Answer:
240 feet
Step-by-step explanation:
Given that,
The object falls 400 feet in 5 seconds.
We need to find how far it fall in 3 seconds.
5 seconds = 400 feet
1 second = 80 feet
So,
In 3 seconds,
d = (80×3) feet
= 240 feet
So, it will fall 240 feet in 3 seconds.
