Question 4

Answer is 8 feet

10 ft ladder = hypotenuse
6 ft away = one side

That makes a right angled triangle
so
by using Pythagoras theorem,

AB² + BC² = AC²
6² + BC² = 10²
36 + BC² = 100
100 - 36 = BC²
64 = BC²
8 = BC

Similarly, in Q 5

Answer is 12 feet

4)

as shown in image

the height of tree can be calculated using pythagauras theorem

so

6^2 + x^2 = 10^2

36+x^2 = 100

x^2 = 100-36 = 64

x=√64

x= 8

so height of tree upto ladder reach is 8 feet so option 3 is answer

5) using same rule above

9^2 + x^2 = 15^2

81 + x^2 = 225

x^2 = 225 - 81 = 144

x = √144

x = 12

so height of tree upto ladder reach is 12 feet, so option 3 is answer

Answer:

x=\frac{5}{4}

Step-by-step explanation:

2x+\frac{5}{8}=3x-\frac{5}{8}

Subtract 5/8 from both sides:-

2x+\frac{5}{8}-\frac{5}{8}=3x-\frac{5}{8}-\frac{5}{8}

2x+\frac{5}{8}-\frac{5}{8}

Add like terms:-

  • \frac{5}{8}-\frac{5}{8}=0
  • =2x

3x-\frac{5}{8}-\frac{5}{8}

Rule:- \frac{a}{c} \pm \frac{b}{c}=\frac{a \pm b}{c}

  • \frac{-5-5}{8}

Subtract, -5-5=-10

  • =\frac{-10}{8}

Cancel common factor: 2

  • =-\frac{5}{4}
  • =3x-\frac{5}{4}

---------------

2x=3x-\frac{5}{4}

Now, subtract 3x from both sides:-

2x-3x=3x-\frac{5}{4}-3x

-x=-\frac{5}{4}

Divide both sides by -1:-

\frac{-x}{-1}=\frac{-\frac{5}{4}}{-1}

x=\frac{5}{4}

dezoksy [38]

Answer:

12/30

Step-by-step explanation:

So we know that the denominator-numerator=18

And we also know that it's equal to 4/10 or 2/5.

Soooooooooooooo the most easiest is just to trial and error: 12/30

But I don't really know the more complex formula...
