Answer:
53lbs
Step-by-step explanation:
if he bought three bags of gravel that are 20 lbs. each then he would have 60 lbs. of gravel. In the end he only had 7 pounds left so you would subtract 7 from 60 and get 53 pounds.
7+x=60 or 60-7=53
i hope this helped!
All you have to do is multiply 8 by 20 which is 160
Answer:

Step-by-step explanation:
A line that passes through the point (4,-6) has a slope of 5/-4. Which of the following gives the equation of the line?
With the slope of 5/-4, and the ordered pair (4,-6) :
let m = 5/-4 (slope),
x1 = 4
y1 = -6
We can use those given values into the point-slope formula:
y - y1 = m(x - x1)
Plugging in those values will give you the answer:
y - (-6) =
(x - 4)
Distribute
into the terms inside the parenthesis:
y + 6 =
+ 5
Subtract 6 from both sides to isolate y:
y + 6 - 6 =
+5 - 6
The equation of the line in slope-intercept form is:
