Answer:
the sum of two numbers is 27. their difference is 5. find the number
Step-by-step explanation:
Let x be the first number and y be the second number ... so we have
x + y = 27
x - y = 5 Adding the equations, we have
2x = 32 Dividing through by 2, we have
x = 16 And substituting or x in the first equation, we have
16 + y = 27 Subtract 16 from both sides
y = 11
1) first find the ratio of gallons to minutes which is 150/6=25, so 25 gallons a minute.now divide 20,000 by 25=800 and that is the answer
2)so, we found the proportion 25:1 or 25 gallons a minute
3)we do the same thing we did for find, find the ratio per square feet 700/2=350, next we divide 1960 by 350. that should get you 5.6
Hope I helped! :)
The answers would be 3, 3, 4, 4, 5, 5. those are the answers. I don't know if that is what you wanted me to answer or not.
