Answer:
Step-by-step explanation:
Given two similar triangles.
Corresponding parts of similar figures have same ratio.
<u>Use ratios to find the value of x:</u>
- (4x - 5)/(x + 7) = 35/12.5
- (4x - 5)/(x + 7) = 14/5
- 5(4x - 5) = 14(x + 7)
- 20x - 25 = 14x + 98
- 20x - 14x = 98 + 25
- 6x = 123
- x = 123/6
- x = 20.5
<u>Find the value of FG:</u>
The total number of books is 900 books if 5% of the books is 45
4 multiple choice questions
3 answers per question
4 × 3 = 12
<em>12 possible answers total</em>
12 - 4 = 8
<em>8 incorrect answers
</em><em>4 correct answers
</em><em>
</em>3 × 3 × 3 × 3 = 81
<em>
</em><em>81 possible ways they can answer
</em><em>
</em>Only one of those ways is 100% correct.
<em>
</em>81 - 1 = 80

4/5 pounds for 3 $
hence for 1$ we get 4/15 pounds
then for 10$ we would get 4*10/15 =40/15 = 8/3
