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!

The solution for given linear equation systems is (3,-4).
Option: C
<u>Step-by-step explanation:</u>
The given equations are 5x+3y=3 and x+y= -1.
Let us isolate x value from equation 5x+3y=3.
5x = 3-3y.
.
Substitute this x value in equation x+y= -1.
.
After taking LCM for the denominator,
.
3-3y+5y=-5.
2y=-8.
y=-4.
For substitute the y value.
.
.
.
x=3.
∴ The solution is (3,-4).
