Answer:
Step-by-step explanation:
Let the 3 numbers be 
and 
As per question,
Also, 7 times the second number is twice the first, so
Again, twice the second number is 6 times the third number, so
Now, multiply equations 1 and 2. This gives,
Therefore, the ratio of the product of the first and the third numbers to the square of the second number is
You can add 16 up until it reaches 120 If it goes over 120 then delete one of the 16 to only get 7 the answer is 7
Answer:
143.75
Step-by-step explanation:
The tip is the cost times the tip rate
tip = cost * rate
The cost is 125 and the rate is 15%
tip = 125 * 15%
Change this to decimal form
tip = 125 *.15
= 18.75
The total bill is the cost plus the tip
total bill = cost + tip
= 125 + 18.75
= 143.75
Answer:
a. x>
23
/3
b: x<
13/5
Step-by-step explanation:
A: Step 1: Subtract x from both sides.
4x−15−x>x+8−x
3x−15>8
Step 2: Add 15 to both sides.
3x−15+15>8+15
3x>23
Step 3: Divide both sides by 3.
<u>x>
23/3</u>
B: Step 1: Subtract 7x from both sides.
2x+13−7x>7x−7x
−5x+13>0
Step 2: Subtract 13 from both sides.
−5x+13−13>0−13
−5x>−13
Step 3: Divide both sides by -5.
Answer: x<
13/5
