Example Question #51 : Algebraic Concepts
What is the value of the expression?
First you add what is inside the parentheses.
.
Then, we multiply,
.
This leaves us with our answer of 16.
Example Question #52 : Algebraic Concepts
A pencil costs $1.03 and Elena wants to purchase 386 pencils. Which expression gives the best estimate of the total cost of Alex's purchase in dollars?
To solve, we round $1.03 to $1.00 and round 386 pencils to 400.
Then we would multiply to find the answer, so would give us the best estimate.
Example Question #53 : Algebraic Concepts
Find the value of the expression.
To solve the expression, you must first solve inside the parentheses, so
.
Then we divide 2 by 2 and are left with our answer, 1.
Example Question #54 : Equations
Caitlin received tickets to a concert for Friday night. She divides them equally among herself and her four friends. Which of the following expressions shows the number of tickets each person received?
Including Caitlin, there are 5 total people receiving tickets.
If she is going to divide them among her friends, then we would use division,
Example Question #55 : Equations
Solve for .
First we add and are left with
.
Then we subtract and are left with
.
Finally, in order to get the alone, we divide each side by 5 and are left with
.
Example Question #54 : Equations
Solve for .
Following the order of operations, we must do the work inside the parentheses first, so we are left with
.
Then we must multiply and are left with
.
Finally
.
So
.
Example Question #54 : Algebraic Concepts
Five more than a number is equal to of twenty-five . What is the number?
From the question, we know that plus a number equals of . In order to find out what of is, multiply by .
, or .
The number we are looking for needs to be five less than , or .
You can also solve this algebraically by setting up this equation and solving:
Subtract from both sides of the equation.
Example Question #55 : Algebraic Concepts
Solve for :
To solve an equation, first combine like terms. Move the over to the other side of the equation by adding :
Next, remove the from the variable by dividing by .
The answer is .
Example Question #1 : Solve Unit Rate Problems: Ccss.Math.Content.6.Rp.A.3b
At a local market, farmers trade produce to obtain a more diverse crop. A farmer will trade turnips for ears of corn. If a man has ears of corn, then how many turnips can he get?
Ratios can be written in the following format:
Using this format, substitute the given information to create a ratio.
