So we basically reverse it. 56 divided by ? =4. So we divide 56 by 4 which is 14. So the number of friends is 14
Answer: the reason why 3x - 30 = 0 is because x = 10
Step-by-step explanation:
3x - 30 = 0
first we try to get the value of x
so
3x = 30
x = 30/3
x = 10
so the reason why 3x - 30 = 0 is because x = 10
to confirm this
we substitute the value of x=10 into the equation
3x - 30 = 0
3*10 - 30 = 0
30 - 30 = 0
Yes this is true when a system has infinite solution on line the lines are called coinciding
The slope is -2 because if you find two points on the graph ie: (0,0) and (3,-6) and use the slope formula- (y2-y1)/(x2-x1)
(-6-0)/(3-0)= -6/3= -2
