It is given in the question that
Ann, Chang, and Kareem sent a total of 89 text messages over their cell phones during the weekend. Ann sent 9 fewer messages than Chang. Kareem sent 3 times as many messages as Ann.
Let number of messages Chang sent be x. And Ann sent 9 fewer than Chang, so Ann sent (x-9) messages. And Kareem sent 3 times as many messages as Ann, so Kareem sent 3(x-9) messages.
And the total messages are 89. That is

Combining like terms

So Chang sent 25 messages, Ann sent

And Kareem sent

Answer:
4x - 5y = 10
Step-by-step explanation:
Any line parallel to 4x - 5y = 35 will have the same equation EXCEPT that the constant will be different.
Starting with 4x - 5y = 35, replace x with the given x-coordinate -5 and the given y-coordinate -6, and finally the given 35 with the constant C:
4(-5) - 5(-6) = C, or
-20 + 30 = C. Thus, C = 10, and the equation of the new line is
4x - 5y = 10
1 1/2 is the correct answer
Step-by-step explanation:
X- (-12)=25
X+12=25
X=25-12
X=13

Answer:
QR & ST ---> Parallel
ST & QS ---> Perpendicular
RT & QR ---> Perpendicular
QS & RT ---> Parallel
Step-by-step explanation:
2 lines are said to be parallel lines if they will never intersect with each other.
2 lines are said to be perpendicular lines if angle between both the lines are 90°.
