How many deciliters are equivalent to 9 cups? Use the conversion table to find the answer. Round to the nearest tenth.
21.3 dL
42.7 dL
213.3 dL
426.6 dL

 The correct option is (a) 21.3 dL.

Step-by-step explanation:  We are given to find the number of deciliters that are equivalent to 9 cups.

Given that,

1 cup = 0.237 liters.

We know that

1 liter = 10 deciliters. So, we get

0.237 liters = 0.237 × 10 deciliters = 2.37 deciliters.

This implies that

1 cup = 2.37 deciliters.

Therefore, we get

9 cups = 2.37 × 9 deciliters = 21.33 deciliters.

Rounding to nearest tenth, we get

Thus, 9 cups are equivalent to 21.3 deciliters.

Option (a) is CORRECT.

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.
