3/5 = 24/40 =?/60. what comes at the question mark?​
kherson [118]

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>

(20 points!) In triangle RSW, line segment RW is a median and is equal to 27 cm. What is the length of RX?
Fofino [41]

Answer:

Option D. 18 cm

Step-by-step explanation:

we know that

A <u><em>centroid</em></u> of a triangle is the point where the three medians of the triangle meet.

A median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle.

The centroid divides each median in a ratio of 2:1

In this problem the centroid of triangle RST is the point X

so

\frac{RX}{XW}=\frac{2}{1}

RX=2XW -----> equation A

RX+XW=27 -----> equation B

substitute equation A in equation B

2XW+XW=27

Solve for XW

3XW=27

XW=9\ cm

Find the value of RX

RX=2XW  ----- RX=2(9)=18\ cm

Help me pls :D Make the equations match with the number
poizon [28]

Answer:

18 + s = 33 (drag to 15)

27 = 9 × s (drag to 3)

40 - s = 23 (drag to 17)

5 × s = 35 (drag to 7)

18/s = 3 (drag to 6)

m/5 = 10 (drag to 50)

m + 14 = 18 - m (drag to 2)

m + m + 12 = 22 (drag to 5)

n + 7 = 18 (drag to 11)

n-9 = 22 (drag to 31)
