Answer:
Substitute the known values into the formula: 140 = 7(w)(5).
Solve for the unknown: w = 4 m.
Check:
140 = 7(w)(5) => w = 140/(5 x 7) = 140/35 = 4. => Correct.
Substitute the known values into the formula:
7 = 140(w)(5).
Solve for the unknown: w = 7 m.
Check:
7 = 140(w)(5) => w = 7/(140 x 5) = 7/700 = 1/100. => Incorrect.
Substitute the known values into the formula:
5 = 7(w)(140).
Solve for the unknown: w = 2 m.
Check: 5 = 7(w)(140) => w = 5/(7 x 140) = 5/840 = 1/168. => Incorrect.
Hope this helps!

Answer:31/40
Step-by-step explanation:
To add you have to have a common denominator. To get that you can multiply each fraction by one in different ways. 2/5 *8/8= 16/40 and 3/8* 5/5= 15/40 and then add those two to give you 31/40.

Answer:
Y-intercept is (0, -13)
X-intercept is at (13/5, 0)
Step-by-step explanation:
When it's in this form, y = mx + b, you automatically know what the y-intercept is (b).
So the y-intercept is (0, -13)
To algebraically find this, you'd plug in a 0 for x, since the y intercept is when it crosses the y-axis, which is located at x = 0.
To find the x intercept, you'd do the opposite of the y-intercept, which is plugging in a 0 for y and solving for x. The x-axis is located at y = 0.
0 = 5x - 13
13 = 5x
x = 13/5
The x-intercept is at (13/5, 0)
I hope this helped!
