Step-by-step explanation:
<em>Vamsi is X years old</em>
Vamsi = X
<em>his brother is 3 years elder to him</em>
Brother = X + 3
<em>his uncle is 4 times his age</em>
Uncle = 4X
<em>his aunt is 5 years younger than his uncle</em>
Aunt = Uncle - 5
<em>what will be the age of his uncle 6 years from now</em>
= 4X + 6
<em>what are the ages of vamis brother, uncle and aunt?</em>
Assume Vamis = 15 years
Brother = X + 3 = 15 + 3 = 18
Uncle = 4X = 4 * 15 = 60
Aunt = Uncle - 5 = 60 - 5 = 55
<em>what will be the age of his uncle 6 years from now</em>
Uncle = 4X + 6 = 60 + 6 = 66
Answer:
(- 2, 2 )
Step-by-step explanation:
Given the 2 equations
y = x + 4 → (1)
y = - 2x - 2 → (2)
Substitute y = x + 4 into (2)
x + 4 = - 2x - 2 ( add 2x to both sides )
3x + 4 = - 2 ( subtract 4 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
Substitute x = - 2 into either of the 2 equations abd evaluate for y
Substituting into (1)
y = - 2 + 4 = 2
solution is (- 2, 2 )
The gradient of a line depends on how steep it is. The gradient of y=1/3x is 1/3 so you can use any other number that is higher than 1/3 eg y=2
Answer:
C =-x + 550
Step-by-step explanation:
Complete question
<em>At $350 per person, an airline anticipates selling 200 tickets for a particular flight. At $450 per person the airline anticipates selling 100 tickets for the same flight .Find the linear equation between the cost per ticket and the number of tickets.</em>
<em></em>
Find the complete question attached
Let x be the total number of tickets sold
C be the cost per ticket
If C = $350, x = 200
when C = $450, x = 100
Get the slope
m = C2-C1/x2-x1
m = 450-350/100-200
m = 100/-100
m = -1
Substituting into the point slope form of the equation;
C - C1 = m(x-x1)
Substituting m = -1, C1 = 350 and x1 = 200
C - 350 = -1(x-200)
C - 350 = -x + 200
C = -x + 200 + 350
C = -x + 550
Hence the required linear equation is C =-x + 550
Answer: 300
Step-by-step explanation:
20% of 240 is 48. The local business gives 48 dollars. 5% of 240 is 12. The principal gives $12. 48+12+240=300 dollars raised.
