Answer:
35 plants
Step-by-step explanation:
For this case we can make the following rule of three:
4 gallons --------------> 14 plants
x --------------------------> 35 plants
From here, we clear the value of x.
We have then:
therefore, 10 gallons are needed to irrigate 35 plants.
Answer:
it will take 10 gallons to water 35 plants
 
        
                    
             
        
        
        
Answer:
20
Step-by-step explanation:
We write what we know.
Jimmy
$50/mo   app 65¢ or .65
Lisa
$55/mo   app 40¢ or .40
a = number of apps
The difference will come from the number of apps, a.
We need them to equal each other so let's write an equation.
$50 + .65a = $55 + .40a
We need to solve for a.
$50 + .65a = $55 + .40a     subtract $50 for each side.
$50 - $50 + .65a = $55 - $50 + .40a
.65a = $55 - $50 + .40a
.65a = $5 + .40a     subtract .40a from each side
.65a - .40a = $5 + .40a - .40a 
.65a - .40a = $5 
.25a = $5   Divide each side by .25
.25a/.25 = $5/.25
a = $5/.25
a = 20
So Jimmy and Lisa need to download 20 apps for their bill to be the same.
