Hello.
The answer to 1 is <span>$3,180
All you have to do is divide 21,200 by 15%
The answer to 2 that is also true. You would have to find the unit rate to be able to find how much miles to operate.
Have a nice day</span>
Answer:
S = 20 + 0.5*x (S is the total bill, x is the number of text messages)
Step-by-step explanation:
The cell phone company have a fixed value you have to pay every month, independently of the number of text messages you send, and that is $20.
For each text message, you pay an additional %0.50.
So, if you send 'x' text messages in a month, you will pay the fixed $20 plus $0.5 for each text messages: you will pay 0.5 times x for the messages.
So, we can formulate the following equation:
Being "S" the total price you will pay:
S = 20 + 0.5*x
Answer:
see explanation
Step-by-step explanation:
Factor the numerators/ denominators where possible
x² + 7x + 10 = (x+ 2)(x + 5)
x² - 3x - 18 = (x - 6)(x + 3)
x² + x - 2 = (x + 2)(x - 1)
Hence
= ×
Cancel the factors (x + 2) and (x + 3) on numerator/denominator
= ← in simplest form
The denominator of the product cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.
solve x - 1 = 0 ⇒ x = 1 ← restricted value
