So you first have to draw a line down the middle through the = then subtract either 2x or 3x (I did 2x) on both sides and that should give you 1x+3=12. then I subtracted 3 from the twelve and that gave me 1x=9 and then you divide 1 on each side (which crosses out the x) and so the answer that I got was x=9!
X divided by two is 5
So you multiply 5 and 2 to get 10. Therefore x equals 10
Answer:
D)
Step-by-step explanation:
A. That the rate does change , hope that helps !!
Maury = 120/10 (12 calls/hour)
Tyra = 120/8 (15 calls/hour)
Together they are 27 calls per hour.
120 / 27 = 4.4444444444
So it'd take them 4.44444444 (recurring) hours to make 120 calls.
