Work Shown:

3 blue + 3 red = 6 pens that are either blue or red

4 black + 3 blue + 3 red = 10 pens total

Y = -3x +10 3x +y = 5 substitution method

spayn [35]

Answer:

no solutions

Step-by-step explanation:

y = -3x +10

3x +y = 5

Substitute the first equation into the second equation

Let every instance of y in the second equation be replaced with -3x+10

3x+ (-3x+10) = 5

Combine like terms

10 =5

This is never true so there are no solutions

(These are parallel lines with the same slope but different y intercepts)

Answer:

The required expression is $\frac{y}{4}-3$ .

The value of the expression when y=20 is 2.

Step-by-step explanation:

Consider the provided phase.

3 less than the quotient of a number y and 4

The quotient of a number y and 4 can be written as: $\frac{y}{4}$

Now 3 less than the quotient of a number y and 4 can be written as:

$\frac{y}{4}-3$

Hence, the required expression is $\frac{y}{4}-3$ .

Now evaluate when y=20.

Substitute y=20 in above expression.

$\frac{20}{4}-3$

$5-3$

$2$

Hence, the value of the expression when y=20 is 2.
