What is the sap collected from each tree

5 gallons is your answer

we know that

total amount of sap =[3*(1/4)+2*(3/8)+4*(5/8)+1*(1)]

total amount of sap =[(3/4)+(6/8)+(20/8)+(1)]

total amount of sap =[(3/4)+(3/4)+(10/4)+(4/4)]

total amount of sap =[20/4]

total amount of sap =5 gallons

total of trees=10

[amount of sap collected from each tree]=total amount of sap/total of trees

[amount of sap collected from each tree]=5/10> 0.5 gallons per tree

the answer is

0.5 gallons

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
