Answer:
B
Step-by-step explanation:
AS is an angle bisector, thus the ratio of the sides of the triangle is equal to the ratio of the corresponding parts of RT, that is
= 
, substituting values
= 
( cross- multiply )
7.5x = 31.5 ( divide both sides by 7.5 )
x = 4.2
Thus
RT = 3.5 + x = 3.5 + 4.2 = 7.7 → B
Add Two-thirds to both sides
solution:
x-2/3= 5/6
We have to find how this can be solved for "x" in one step
Remember that,
We we add or subtract same number from both sides of a equation, the equation still remains true
Therefore, from given,
x-2/3=5/6
Add Two-thirds to both sides
x-2/3+2/3=5/6+2/3
x=5/6+2/3
x=9/6
Add Two-thirds to both sides to solve the sum
Answer:
no association because there is no specific pattern
Step-by-step explanation:
his father's age= 4x
his mother's age= 4x- 7
his age= x
x+4x+4x-7=101
x+ 4x+ 4x= 101+ 7
9x= 108
= 
x= 12

Answer:
3 bulbs should be flawed
Step-by-step explanation:
2+ 18 = 20
20 bulbs were examined
2/20 = 1/10 were flawed
looking at the next 30 bulbs
30 * 1/10 = 3
3 of the next 30 bulbs should be flawed
