Answer:
5
Step-by-step explanation:
This is a problem most likely relating to order of operations (i.e. PEMDAS) where the letters stand for the order you should solve the problem in.
P= Parenthesis
E= Exponent
M= Multiplication
D= Division
A= Addition
S= Subtraction
With this in mind, I solved (14+3) and (2x6), which gave me 17 and 12 respectively. After I subtracted 12 from 17 and got 5 as the answer
What do we know from the problem?:
*bill is $58
*wants to leave 80% tip
what's missing?:
what's the total bill
How to solve it?:
first we have to take care of the 80% so..
80/100= 0.80 or 0.8
step 2:
$58 x 0.8= $46.40
Step 3:
ADD the total bill which is $58 and add the $46.40
$58 + $46.40= $104.4
FINALLY: Arun's total bill was $104.40
Answer:
3a-3b-5c
Step-by-step explanation:
((3a-3b)²-(5c)²)÷(3a-3b+5c)=((3a-3b-5c)(3a-3b+5c))÷(3a-3b+5c)=3a-3b-5c
Taking natural logs of both sides, we get
0.015t=ln 3
t = ln 3/0.015 = 73.24
The answer is 73.24 years.
It is ten times bigger than the other
