Answer:
Step-by-step explanation:
In algebra we work with variables and numerals. To evaluate an algebraic expression simply means that you are going to determine the value of an expression by substituting and evaluating using the operation order.
in summary in order to evaluate an algebraic expression
- you must identify the variable and its value
- you will substitute the given value for the variable
- complete the necessary calculations
Take for example;
evaluate 2a + 4b - 2c
given that a = 2 , b = 1 , c = 5
since you already know the value of the variables you substitute them into the question
we have
2(2) + 4(1) +2 ( 5)
4 + 4 + 10

Answer:
$1.56
Step-by-step explanation:
You have to divide the cost $12.48 and divide it with the 8lbs and it gives you $1.56, if your not sure that its the right answer than just multiply the answer with the 8lbs, your welcome!
Answer:
i. 10 units (Carol's house is 10 units on the right from Ann's house)
ii. -10 units (Carol's house is 10 units on the left to Ann's house)
Step-by-step explanation:
A number line is a system that can be used to express the location of directed number on a straight line. It has an origin which is taken to be zero (0).
In the given question, Ann's house is located at 0 of the number line. Let 1 block be represented by 1 unit on the number line.
Thus, Ben lives 8 blocks from Ann implies that Ben's house is at 8 units from Ann's house.
Given that Carol's house is 2 blocks from Ben implies that Carol's house is 2 units from Ben.
So that,
The possible locations of Carol's house depends on its position with respect to Ann's house.
i. Carol's house = 8 + 2
= 10 units
This implies that Carol's house is 10 units on the right from Ann's house.
ii. Carol's house = - 8 - 2
= -10 units
This implies that Carol's house is 10 units on the left to Ann's house.
Answer:
The distance from B to B' is 5 units
Step-by-step explanation:
The complete question is
Polygon ABCD is translated to create polygon A'B'C'D'. Point A is located at (1,5) and point A' is located at (-2,1). What is the distance from B to B'?
we know that
In a translation the figure maintains its dimensions and internal angles
so
AA'=BB'=CC'=DD'
The distance BB' is the same that the distance AA'
<em>Find the distance AA'</em>
the formula to calculate the distance between two points is equal to
we have
A(1,5),A'(-2,1)
substitute in the formula
therefore
The distance from B to B' is 5 units
