Answer:
number of members in 2006=190
230members on 2010
Step-by-step explanation:
2008-2006=2
20*2+150= 190 ans (1)
b)
20x+150=230
20x=230-150= 80
x= 80/20=4---ans (2)
Answer:
x = 
Step-by-step explanation:
The segment from the vertex to the base is a perpendicular bisector.
Using Pythagoras' identity on the right triangle on the left.
x² = 2² + 3² = 4 + 9 = 13 ( take the square root of both sides )
x = 
Parenthesis are something you can use in math problems that mean anything inside of them is what you have to solve first. In PEMDAS P is parenthesis which means that is first.
15x+10z is equivalent to 5(3x+2z)
Answer:
The correct answer is - 12.
Step-by-step explanation:
Given:
Total number of people = y = 39x+50
Total amount spent y = 518
Solution:
The equation for the number of people who attended the dinner
y = 39x+50
The cost of dinner is equally divided by number of people =
then, 518 = y
placing value, 518 = 39x+50
x = (518-50)/39
= 468/39
= 12
Then number of people attended the dinner = 12
