The answer (usually called the 'solution') is the one and only number that 'n' can be if that equation is a true statement. Here's a suggestion of a procedure you can use to find it:

1.8 + 7n = 9.5 - 4n

Add 4n to each side: 1.8 + 11n = 9.5

Subtract 1.8 from each side: 11n = 7.7

Divide each side by 11 :  n = 0.7

olga55 [171]

From the table we can conclude that after 2 minutes the height of the water is increased by 4.
Example: In minute 2 it was 8 inches, in minute 4 it was 12 inches. (12-8=4)
This means that if the height of the water is increased by 4 inches for 2 minutes, then for 1 minute is increased 4/2=2 inches.
The following statement best describes how the slope relates to the height of the water in the pool:
The height of the water increases 2 inches per minute.

Two positive integers have a product of 176. One integer is 5 less than the other integer. Which equation can be used to find th

faust18 [17]

$xy=176$
$y=x-5$

$\implies x(x-5)=176\implies x^2-5x-176=(x+11)(x-16)=0$
$\implies x=-11, x=16$

Since $x>0$ , we take $x=16$ , which means $y=16-5=11$ .
