Question 4: Simplify the following algebraic fractions (answer to any question is fine :) )
1 answer:
Answer:
(a) (x times x) + (5 times x) + 4
Step-by-step explanation:
Using my answer you first do exponent, so x times x then 5 times x and then 4 times x BUT keep those numbers apart still!
okay now we will take and add that value to 4 so we now have the numerator‘s value and for the denominator you will take
And multiply 4 times x and add those two answers and finally add the 3 you will have finished the denominator and FINALLY divide the numerator‘s result by the denominato’s result and you now have your answer.
the secret? Order of Operations or PEMDAS
1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)
5. BOOM the result will be your answer!

Answer:
400 megabytes of data used will make the cost from either company equal.
Step-by-step explanation:
Given that:
Per month charges of Company A = $80
Charges of 100 MB = $5 =
Let,
x be the number of MBs consumed.
y be the total charges.
y = 0.05x+80
Per month charges of Company B = $60
Charges of 100 MB = $10 = $0.1 per MB
y = 0.1x+60
For equal charges;
0.05x+80 = 0.1x + 60
80-60 = 0.1x-0.05x
20 = 0.05x
Hence,
400 megabytes of data used will make the cost from either company equal.
