Answer:

Step-by-step explanation:

Solution

3x - 3 2x - 2

===== = ====== Cross Multiply

5 4

4(3x - 3) = 5(2x - 2) Remove the brackets. Distributive Property

12x - 12 = 10x - 10 Subtract 10 x from both sides

12x-10x - 12 = 10x-10x - 10 Combine

2x - 12 = - 10 Add 12 to both sides

2x-12+12 = -10 + 12 Combine

2x = 2 Divide by 2

2x/2 = 2/2

Which expression represents the shaded length of the number line below? Choose 1 answer: Choose 1 answer: (Choice A) A 34×32\dfr

Anit [1.1K]

Answer:

$Expression = \frac{2}{3} * \frac{5}{4}$

Step-by-step explanation:

See attachment for number line

From the attachment, we have the following details:

The first shade of blue covered 10 blocks

The second shade of blue covered 5 further blocks which totaled to 15

So, the fraction of the blue blocks is:

$Blue = \frac{10}{15}$

Divide fraction by 5/5

$Blue = \frac{10/5}{15/5}$

$Blue = \frac{2}{3}$

Also from the attachment:

The shaded block stopped at the fraction:

$Shaded = \frac{5}{4}$

So, the expression that represents this scenario is:

$Expression = Blue * Shaded$

$Expression = \frac{2}{3} * \frac{5}{4}$
