You got add all the numbers up and divide it by how many numbers there are to get the average.
9.4 +9.7 + 9.9 + 9.8 = 38.8 divided by 4 =9.7 is Joey's average.
9.5 +9.2 +9.7 +9.6 =38 divided by 4 = 9.5 is Carlos' average.
Joey has more average by 0.2.
Answer:
The required biconditional statement is: If Smith is guilty, if and only if Jones is innocent.
Step-by-step explanation:
From the provided statement.
The statement is: If Smith is guilty, then Jones is innocent.
The converse is: If Jones is innocent, then Smith is guilty.
The combination of a conditional statement and its converse is called biconditional statement.
The biconditional statement contains if and only if phrase between two part of the statement.
Which means the statement and converse both are true.
Therefore, the required biconditional statement is: If Smith is guilty, if and only if Jones is innocent.
Answer:
- given
- addition property of equality
- addition property of equality
- division property of equality
- symmetric property of equality
Step-by-step explanation:
In step 2, -3x was added to both sides in accordance with the addition property of equality.
The same property lets you add 18 to both sides, as in step 3.
The division property of equality lets you divide both sides of the equation by 5. (Or, the multiplication property lets you multiply by 1/5.)
Swapping sides of the equal sign is allowed by the symmetric property of equality.
We have to factor becasue
area=legnth times width
area=4x^2+28x+49
area=(2x+7)(2x+7)
area=(2x+7)^2
legnth =width
we arent' given area so we can't solve
but, , since it is a squaer room, legnth=width so √area=legnth=width
