fresh grapes lose 80% of their weight while drying. what weight of fresh grapes should you dry to get 140 grams of dried grapes?

The weight one can dry to get 140 grams is 700 grams

Step-by-step explanation:

Fresh grapes looses 80 percent of it weight while drying . To get 140 grams of dried grape we need to know the weight of the fresh grape.

Let the fresh grape weight = y grams

80% of the fresh grape weight will be =  80/100 × y grams

The weight of fresh grape you should dry to get 140 grams = Fresh grape weight - 80% of the fresh grape weight

140 = y - 80/100 × y

140 = y - 0.8 y

140 = 0.2y

divide both sides by 0.2

y = 140/0.2

y = 700 grams

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.
