Answer: Yes!

Step-by-step explanation:

If the x and y coordinates form proportional relationships, then there is some non-changing number (a constant) that when multiplied times x will create y. In this example, that number is 3 (y = 3x), and is called the constant of proportionality. ... It is a positive number.

solniwko [45]

Answer:

$9.60 for 42 fl oz

Step-by-step explanation:

$6.15 x 2=$12.30

$12.30 for 44 fl oz

$12.30-$9.60=$2.70

you would be paying $2.70 for 4 fl oz when 4 fl oz is 93 cent

Find the value of x:
slega [8]

Answer:

x = 20

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Using ΔAHC , then

∠ACH = 180 - (2x + 100) = 180 - 2x - 100 = 80 - 2x

∠ECD = ∠ACB ( vertical angles are congruent ), thus

∠ECD = ∠ACH + ∠HCB, that is

3x = 80 - 2x + x

3x = 80 - x ( add x to both sides )

4x = 80 ( divide both sides by 4 )

x = 20
