Answer:
45x + 180 = - 720
Step-by-step explanation:
Let the required number be x.
Therefore, product of 45 and x = 45x
180 added to 45x = 45x + 180
Since, 180 Added to the product of 45 and a number totals negative 720.
So, 45x + 180 = - 720
the answer is 250 million years
-5/3
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 2-7)/(4-1)
