W / 7 = 0.3
0.3 x 7 = 2.1 = w
w = 2.1
$17500 was invested in the first account at a rate of return of 10% (after a year) while $11000 was invested in the second account at a rate of 4% loss over the same period.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount of money invested at 10% and y represent the amount of money invested at a loss of 4%, hence:
x + y = 28500 (1)
Also:
(x * 1 year * 0.1) + (y * 1 year * -0.04) = 1310
0.1x - 0.04y = 1310 (2)
From equation 1 and 2:
x = 17500, y = 11000
$17500 was invested in the first account at a rate of return of 10% (after a year) while $11000 was invested in the second account at a rate of 4% loss over the same period.

64 divided by 16 is 4,
80 divided by 16 is 5.
Add total number of feet together.
=5 3/8+ 7 1/2+ 8 2/5
=5.375 + 7.5 + 8.4
=21.275 total feet of pipe (rounded to the tenths would be 21.3 feet)
