Answer:
m = 10
Step-by-step explanation:
Given w is inversely proportional to m then the equation relating them is
w = 
← k is the constant of variation
To find k use the condition w = 8, m = 25 , then
8 = 
( multiply both sides by 25 )
200 = k
w = 
← equation of variation
When w = 20 , then
20 = ( multiply both sides by m )
20m = 200 ( divide both sides by 20 )
m = 10
The measurements that show equal length is 15 yd and 540 in, 195 ft and 2340 in, 5280 yd and 15840 ft
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
1 ft = 12 in; 1 yd = 3 ft and 1 yd = 36 in.
Hence:
15 yd = 15 yd * 36 in per yd = 540 in
195 ft = 195 ft * 12 in per ft = 2340 in
5280 yd = 5280 yd * 3 ft per yd = 15840 ft
The measurements that show equal length is 15 yd and 540 in, 195 ft and 2340 in, 5280 yd and 15840 ft

<h2>
The required equation of line is 2x - 3y - 9 = 0.</h2>
Step-by-step explanation:
Here, slope(m) = 
and y - intercept(c) = -3
To find, the required equation of line = ?
We know that,
The equation of a line with slope m and y-intercept c is given by
y = mx + c
∴ The required equation of line
y = x + (- 3)
⇒ y = x - 3
⇒ y + 3 = x
⇒ 3(y + 3) = 2x
⇒ 3y + 9 = 2x
⇒ 2x - 3y - 9 = 0
Thus, the required equation of line is 2x - 3y - 9 = 0.
Answer:
x = -2
Step-by-step explanation:
2x + 4 = 0
2x = -4
2x/2 = -4/2
x = -2
