It is the commutative property of addition
I believe x=116 and z=26. 4z-40=64
4z=104
z=26
180-64=116
Answer:
The answer is C.24 - 9x3 - 8x2 + 15x
Slope is rise over run so since it rose 4 and went 1 to the right the slope would be 4 because 4/1=4
P.S. The actual formula for slope is y2-y1 over x2-x1 so it would be 5-1/1-0 which again is 4/1
Answer: the top box can be the linear equation y=40x+15 and the bottom box is 40
Step-by-step explanation:
If you swim 15 more minutes than your friend and your swam 55 minutes, that means your friend only swam 40 minutes. The set amount of time that your friend swims for <em>x</em> is 40 minutes. So the additional time you swim is <em>b</em>, 15 minutes.
