Answer: 11b+7
Explanation: In order to solve this, you combine the like terms (variables of the same letter and degree, and constants).
(9b+2) + (2b+5)
(9b+2b) + (5+2)
11b+7
The answer would be C.
(7sqrt3)^2 + (7sqrt3)^2 = c^2
49*3 = 147
147+147= c^2
294 = c^2
sqrt 294 = c
17.1 = c
Here, we want to simplify the given expression
We shall use the order of simplification for this
The order is PEDMAS
We shall start with the terms in parentheses before we move to the exponents
We have;
Next is the exponent
The next thing to do is to divide
The next thing to do is to multiply
We then proceed to subtract;
Answer:
2.25×3
Step-by-step explanation:
2 1/4 is equal to 2.25. So a expression could be 2.25×3.
Answer:
C = 60t + 70
Step-by-step explanation:
The total cost of hiring Plumbing Service is given by the equation C = 50t + 70, where C is the total cost in dollar and t is the time in hours.
So, $ 70 is the fixed price and $50 is the rate of charge per hour for the service.
Now if in the next month the rate of charge per hour for the service increased to $60 and the initial charge remains the same then the equation for the total cost of hiring Plumbing Service will become C = 60t + 70. (Answer)
