Solve the proportion 7/5=x/3

Mathematics

kumpel [21]3 years ago

Start with

\dfrac{7}{5}=\dfrac{x}{3}

Multiply both sides by 3:

\dfrac{21}{5}=x

Recall that 21/5=4.2 to claim the correct answer.

Answer:

The answer is 21/5 or 5/21.

Step-by-step explanation:

In order to remove the  3  by which the unknown  "x " is divided by, you must multiply by both sides of the equation by  3 , thus isolating  "x ":

Like this:

\frac{7}{5} x 3 = \frac{x}{3} x 3

If both sides of the equation were not multiplied by 3, we would not maintain equality across the equation, thus reaching an incorrect answer.

Therefore, simplifying the above you get:

x= \frac{5}{21}

Hello,

The two lights flash at the same time every 18 min
at 8:00 h=480 min =480+0*36
at 8:36 h=516 min =480+1*36
...
54 is not divisible by 36
60+12=72 = 2*36 yes
60+24=84 not
120+24=4*36 yes
180+18=198 not

So 2 times are correct 9:12 and 10:24

If DE = 8, PS = 4, and PQ = 3, then what is the scale factor of DEFG to PQRS?
posledela

The scale factor of DEFG to PQRS is: 3/8.

<h3>What is a Scale Factor?</h3>
  • A scale factor of a dilation is the number by which the size of an original figure is changed to a new figure.
  • Scale factor is ratio of corresponding side of new figure to original figure.

Thus:

DE corresponds to PQ.

PQRS is the new figure.

DE = 8; PQ = 3

  • Therefore:

Scale factor of DEFG to PQRS = PQ/DE

Scale factor = 3/8.

Thus, the scale factor of DEFG to PQRS is: 3/8.

Can somebody help me solve this ?
77julia77 [94]

Step-by-step explanation:

volume of sphere = 288

based on formula, V = 4/3πr³

288 = 4/3(3.14)r³

288 = 4.187(r³)

r³ = 288/4.187

r =

\sqrt[3]{68.78}

r = 4.09

= 4.1
