The Green Goober, a wildly unpopular superhero, mixes 3 liters of yellow paint with 5 liters of blue paint to make 8 liters of special green paint for his costume.Write an equation that relates the amounts (in liters) of yellow paint (y) and blue paint (b) needed to make the Green Goober's special green paint.

Answers

Answer 1

Answer:

Let

y------> the amounts (in liters) of yellow paint

b-----> the amounts (in liters) of blue paint

we know that

$(y)/(b)=(3)/(5)$

$y=(3)/(5)b$

therefore

the answer is

$y=(3)/(5)b$

Answer 2

Answer:

Answer:

Hence, the expression that relates b and y is:

$y=(3)/(5)b$

Step-by-step explanation:

It is given that:

The Green Goober, a wildly unpopular superhero, mixes 3 liters of yellow paint with 5 liters of blue paint to make 8 liters of special green paint for his costume.

i.e. the proportion of yellow paint used = $(3)/(8)$

and proportion of blue paint used = $(5)/(8)$ .

Let 'x' be the total mixture formed.

The amount of yellow paint(y)= $(3)/(8)* x$

i.e. $x=(8)/(3)y$

and amount of blue paint(b)= $(5)/(8)* x$

i.e. $x=(8)/(5)b$ .

Hence we can equate x from both the equation to obtain:

$(8)/(3)y=(8)/(5)b\n\n(1)/(3)y=(1)/(5)b\n\n\n5y=3b\n\n\ny=(3)/(5)b$

Hence, equation that relates the amounts (in liters) of yellow paint (y) and blue paint (b) needed to make the Green Goober's special green paint is:

$y=(3)/(5)b$

Determine which ordered pair is a solution of y=2x-3A)(-2,7)
B)(0,3)
C)(-4,-11)
D)(5,-7)

Answers

C) (-4,-11) because when you substitute both numbers into the equation you end with -11 = -11

y=2x-3<=>0=6-3<=>0=3 b) (0,3)

How do you subtract an integer from another integer without using a number line or counters? Give an example.

Answers

For example, if you have -12 - (-16), you just add the absolute value of the two numbers and put a - in front of it. 12 + 16 = 28. Now just put the sign in front of it and your done. -28 is the answer.
