Answer:
(7,9)
Step-by-step explanation:
7x - 8y = -23
7x - 7y = -14
Solve the equation for 7x
7x - 8y = -23
7x = -14 + 7y
Substitute the given value of 7x into the equation 7x - 8y = -23
-14 + 7y - 8y = -23
solve the equation for y
y = 9
substitute the given value of y into the equation 7x = -14 + 7y
7x = -14 + 7(9)
solve the equation for x
x = 7
<u>(7,9)</u>
So, As Helen divides these pencils, she will divided among, herself, and also her other friends.
This would then signify that the expression would look like the following:

We really do not know how many pencils Helen had, so this is why <em>p </em>is in the equation.
Answer:
First we must figure out what the question means. It is asking how the absolute value of 3+10 is equivalent to the absolute value of 3 plus the absolute value of ten.
Next we should solve the expressions: The absolute value of 3 plus 10 is 13. The absolute value of 3 plus the absolute value of 10 is 13. 13 and 13 are the same number.
Therefore, the expressions are equivalent. Thus, having your answer.
Area = Length x Width
A square has even sides so
