Answer:
to answer this you need picture
You need to make a proportion. Then cross multiply and divide to find your answer.
blue 3 12
red 2 x
(2)(12) = 3x
24 = 3x
x = 8
There are 8 red marbles
The answer is interval or ratio. In interval level of measurement, the
distances between have attributes does have a meaning. The best example to be
used here is temperature. The
distance from 40-50 is like the distance from 70-80. While in <span>ratio level of </span>measurement,
there is constantly an absolute zero that is significant. Meaning, that you can
build a meaningful fraction (or ratio) with a ratio variable.
Answer:
x =
, x = 
Step-by-step explanation:
Given
4x² - 16x = 16x - 39 ( subtract 16x - 39 from both sides )
4x² - 32x + 39 = 0
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term, that is
product = 4 × 39 = 156 and sum = - 32
The factors are - 26 and - 6
Use these factors to split the x- term
4x² - 26x - 6x + 39 = 0 ( factor the first/second and third/fourth terms )
2x(2x - 13) - 3(2x - 13) = 0 ← factor out (2x - 13) from each term
(2x - 13)(2x - 3) = 0
Equate each factor to zero and solve for x
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = 
2x - 13 = 0 ⇒ 2x = 13 ⇒ x =
