Solution:
Given ΔPQR ΔUTV.
<em>If two triangles are similar, then the corresponding parts are congruent.</em>
Do cross multiplication, we get
⇒ 14(x - 3) = 8(x + 6)
⇒ 14x - 42 = 8x + 48
Add 42 on both sides.
⇒ 14x = 8x + 90
Subtract 8x on both sides.
⇒ 6x = 90
Divide by 6 on both sides.
⇒ x = 15
The value of x is 15.
Answer:
Step-by-step explanation:
Given that:
4 papers are delivered by first person in one minute.
Rate of delivering one paper
or
Time taken to deliver one paper can be calculated by the formula:
Time taken to deliver one paper by first person =
3 papers are delivered by second person in one minute.
Time taken to deliver one paper by second person =
Total number of papers = 75
Number of papers delivered by first person =
So, number of papers delivered by second person = ()
Time taken to deliver newspapers = Number of newspapers delivered <em>multiplied by </em>Time taken to deliver one newspaper
Time taken by first person =
Time taken by second person =
So, Total time taken can be written as:
