Write the phrase as an expression. then evaluate when y = 20
3 less than the quotient of a number y and 4
expression:
when y = 20, the value of the expression is

When , the value of the expression is

Step-by-step explanation:

By definition, when you divide two numbers, the result is known as the "Quotient":

 Notice that "c" is the quotient of "a" and "b".

Therefore, the expression for "the quotient of a number and 4" is:

Now, "3 less than the quotient of a number and 4" indicates that you must subtract 3 from ; so you can conclude that the expression is:

Substitute into the expresion:

Evaluating, you get that the value of the expression when is:

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

the equation is not included but the answer is (1.50, 2.00, 2.75)
