The Silver Town people went to a fancy restaurant after the big event. Grammy gave the server a $15 tip. If the tip was 20% of the cost of dinner, how much was dinner? Choose Answer:A.$60 B.$45 C.$75 D.$50

Answers

Answer

Find out the cost of the dinner .

To proof

Let us assume that the cost of the dinner be x.

As given

The Silver Town people went to a fancy restaurant after the big event.

Grammy gave the server a $15 tip.

If the tip was 20% of the cost of dinner.

20% is written in the decimal form

$= (20)/(100)$

= 0.2

Than the equation becomes

x× 0.2 = 15

$x = (15)/(0.2)$

x =$75

The total cost of the dinner is $75 .

option (C) is correct .

Hence proved

I agree it's C That's your answer

Sin θ = − 8/17 and θ is in Quadrant III, find tan(θ/2)

Answers

Answer:

tan(θ/2) = -0.25

Step-by-step explanation:

sin(x) = -8/17

x = sin^-1(-8/17)

x = -28.07

tan(θ/2) = tan(-28.07/2)

= -0.25

How can you use algebraic expressions to solve problems?

Answers

Final answer:

Algebraic expressions can be used to solve problems in mathematics by representing unknown quantities with variables, setting up equations based on given information, and using algebraic manipulation to find the values of the variables.

Explanation:

Algebraic expressions can be used to solve problems in mathematics by representing unknown quantities with variables, setting up equations based on given information, and using algebraic manipulation to find the values of the variables. Here is a step-by-step process to solve problems using algebraic expressions:

Read the problem carefully and identify the quantities involved.
Choose variables to represent the unknown quantities.
Write down the information given in the problem as equations using the variables.
Simplify and manipulate the equations using algebraic operations, such as addition, subtraction, multiplication, and division.
Solve the equations to find the values of the variables.
Check your solution by substituting the values back into the original equations.

Final answer:

Algebraic expressions can be used to solve problems by representing unknown quantities with variables and using equations to find their values. It is important to read the problem carefully, identify the unknowns, and set up equations to solve for the variables.

Explanation:

Algebraic expressions can be used to solve problems in mathematics by representing unknown quantities with variables and using equations to find the values of those variables. When faced with a problem, you can set up an algebraic equation using the given information and solve for the unknown variable. For example, if you are asked to find the value of a number when it is multiplied by 5 and added to 10, you can write the equation as 5x + 10 = unknown value, where x represents the unknown number. By solving this equation, you can determine the value of the unknown number.

When using algebraic expressions to solve problems, it is important to carefully read and understand the problem, identify the unknowns, and define variables to represent them. Once the unknowns are identified, you can use the given information to set up equations and solve for the variables. It is also important to check the solution to ensure that it makes sense in the context of the problem.
