Step-by-step Solution:

<em>Let the "?" be known as "x".</em>

Given equation:

3/5 = 24/40 = x/60

Therefore, we obtain the following equations:

  • Equation 1: 3/5 = 24/40
  • Equation 2: 3/5 = x/60
  • Equation 3: 24/40 = x/60

Clearly, the second and the third equation have the "x" variable included. Therefore, we will only focus on the second and third equations.

  • 3/5 = x/60
  • 24/40 = x/60

Note: We can choose any equation to solve for x. The value of x in both equations will be the same as 3/5 = 24/40.

<u>Determining the "x" variable in Equation 2:</u>

  • ⇒ 3/5 = x/60
  • ⇒ 5x = 60 × 3                                             [Cross multiplication]
  • ⇒ 5x = 180                                                        [Simplifying]
  • ⇒ 5x/5 = 180/5                                                   [Dividing]
  • ⇒ x = 36                                                          [Simplifying]

<u>Determining the "x" variable in Equation 3:</u>

  • ⇒ 24/40 = x/60
  • ⇒ 40x = 24 × 60                                        [Cross multiplication]
  • ⇒ 40x = 1440                                                   [Simplifying]
  • ⇒ 40x/40 = 1440/40                                          [Dividing]
  • ⇒ x = 36                                                          [Simplifying]

Therefore, the value of "?" is 36.

Answer:

? = 36

Step-by-step explanation:

<em>Knowing that 3/5 and 24/40 is equal</em>

<em>Therefore we can either use:</em>

<em>3/5 = ?/60 or 24/40 = ?/60</em>

<em>I will use 3/5 = ?/60</em>

<em>Let ? = x</em>

<em>Hence we have</em>

<em>3/5 = x/60</em>

<em>Multiply both sides by 10</em>

<em>6 = x/6</em>

<em>Multiply both sides by 6</em>

<em>x = 36</em>

<em>Therefore, the question mark = 36</em>

<em />

<em>Let's check the answer by Simplifying the fraction:</em>

<em>3/5 = 36/60</em>

<em>3/5 is in already simplify</em>

<em>36/60 simplify = 3/5</em>

<em />

<em>3/5 = 3/5</em>

<em>Thus, the question mark = 36</em>

-5/4-(-1/6) help please
tiny-mole [99]
A way to add fractions that always works is to multiply each numerator by the denominator of the other, then express the sum of products over the product of the denominators.
\dfrac{a}{b}+\dfrac{c}{d}=\dfrac{a}{b}\cdot\dfrac{d}{d}+\dfrac{c}{d}\cdot\dfrac{b}{b}\\\\=\dfrac{ad+bc}{bd}

Here, you have
\dfrac{-5}{4}-\dfrac{-1}{6}=\dfrac{-5\cdot6-(-1)\cdot4}{4\cdot6}=\dfrac{-26}{24}\\\\=\dfrac{-13}{12}=-1\frac{1}{12}

The sum is -1 1/12

A poll asks shoppers at the mall how many cups of water they typically drink in a day. The results of the poll are listed below.
juin [17]

Answer:

D 9.5

Step-by-step explanation:

Write data in increasing order.

3, 5, 5, 6, 6, 6, 7, 7, 8, 8, 8, 8, 8, 8, 9, 9, 10, 10, 10, 10, 11

Find the median

<u>3, 5, 5, 6, 6, 6, 7, 7, 8, 8,</u> 8, <u>8, 8, 8, 9, 9, 10, 10, 10, 10, 11</u>

Median is 8

Lower half of the data is : 3, 5, 5, 6, 6, 6, 7, 7, 8, 8,

First quartile is the median of the lower half of the data=6+6 /2 =6

Upper half of the data is: 8, 8, 8, 9, 9, 10, 10, 10, 10, 11

The Third quartile is the median of the upper half=9+10 / 2 = 9.5

I think eight because if you add those days together they will play again in eight days so that they play on the same day.

Sorry if I got it wrong I tried and that's what counts, right?
