How can parentheses be added to the following equation to make it true?
Viktor [21]

Answer:

8 - (3 x 2) - (1 + 1) = 0

or

8 - 3 x 2 - (1 + 1) = 0

Remember PEMDAS.

If I put parenthesis around 3 x 2, I get 6.

But 8 - 6 = 2

How can we make 2 - 1 + 1 = 0?

If we look at PEMDAS, we know (2 - 1) + 1 = 2, but the answer needs to be 0.

So now try 2 - (1 + 1) and that gives me 0.

And it says parentheses...but you can also do 8 - 3 x 2 - (1 + 1) = 0.

Find the constant proportionality (r) using the value for r, enter an equation in the form of. C=rg that represents the relation
CaHeK987 [17]

Answer:

3.333

C = 3.3333g

Step-by-step explanation:

Given the relation : C = rg

C = Total cost of gasoline

g = Number of gallons of gasoline used

r = constant of proportionality

Picking any point on the graph :

At cost, c = $30

Number of gallons of gasoline used, g = 9

Putting the values into our equation :

C = rg

$30 = r * 9

30 = 9r

Divide both sides by 9

30/9 = 9r / 9

3.333 = r

Hence, constant of proportionality, r = 3.333
