7n-2(n+5)< 3n-16
7n-2n+10<3n-16      Distribute the 2 into n+5   
5n+10<3n-16          Subtract like figures
5n-3n+10<3n-3n-1  Subtract 3n from each side. (You want the variable on ONE side.)
2n+10-10<-16-10     Isolate the variable. Negative plus negative= bigger negative.
2n/2< -26/2             Negative divided by positive= smaller negative. Divide by 2 to isolate.
n<-13

A garden hose emits 9 quarts of water in 6 seconds how much did the water emit in 10seconds
jarptica [38.1K]

Answer:

In 10 seconds, the garden hose will emit 15 quarts of water.  

Step-by-step explanation:

The amount of water emitted by the garden hose over time can be expressed as a ratio:  9/6, or 9 quarts of water for every 6 seconds of time.  We can then simplify this ratio to 3/2, or 3 quarts of water for every 2 seconds of time.  Since the ratio will remain constant, or the same, over time, we can set up an equivalent ratio, or fraction to find the amount of water emitted in 10 seconds:  3/2 = x/10.  We look at the denominators and see that 2 x 5 = 10.  In order to make the ratios equivalent, we would also multiply the numerator by 5:  3 x 5 = 15, which gives us the amount of water emitted in 10 seconds.
