The expression that can be used to determine the total bill is 1.20 x ($47.60)
The total bill paid is the sum of the cost of the meal and the value of the tip.
Cost of the meal = $47.60
Cost of the tip = 0.20 x $47.60
Total cost of the meal = 1.20 x ($47.60)

Step-by-step explanation:
The final expression after combining like terms is 2r + 2.
We are given that;
The expression 8r+7−6r−5
Now,
According to the search results, combining like terms is a common technique for simplifying algebraic expressions. Like terms are terms that have the same variable and exponent.
To combine like terms, simply add or subtract their coefficients and keep the common variable part.
The coefficient is the number that appears in front of the variable.
In given expression, 8r+7−6r−5, there are two like terms: 8r and -6r.
They have the same variable r and exponent .
To combine them, we add their coefficients: 8 + (-6) = 2.
We keep the common variable part r.
So, 8r - 6r = 2r.
The other two terms, 7 and -5, are also like terms.
They are constants with no variables.
To combine them, we add their coefficients: 7 + (-5) = 2.
So, 7 - 5 = 2.
Therefore, by algebra the answer will be 2r + 2.

Answer:
11/16 CHANCE
Step-by-step explanation:
The height of the rocket after 6 seconds is 630 feet
Given the polynomial function that represents the height of the rocket expressed as:
f(t) = -16t^2 + 200t + 6
If the time the rocket take to rise is 6 seconds, hence;
f(6) = -16(6)^2 + 200(6) + 6
f(6) = - 576 + 1200 + 6
f(6) = 630 feet
Hence the height of the rocket after 6 seconds is 630 feet
