7. What is a constant of proportionality? The interval through which a variable changes with respect to time.

The unit rate between two quantities that are directly proportional.

The relationship between two quantities where the ratio comparing them is always

constant.

The ratio between two quanitites simplified sohat the denominator is one.

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

answer: the correct answer is -32

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
