Answer:
(6 , -1)
Step-by-step explanation:
2x+ y = 11 ----------------(I)
y = 11 - 2x --------------------(II)

Multiply the whole equation by 2

x - 10y = 16 --------------------(III)
Substitute y = 11- 2x in equation (III)
x - 10(11 - 2x) = 16
x - 110 + 20x = 16
21x - 110 = 16
21x = 16 +110
21x = 126
x = 126/21
x = 6
Plugin x = 6 in equation (II)
y = 11 - 2*6
y = 11 - 12
y = -1
Answer:
50 students from each grade
Step-by-step explanation:
If we get the similar amount of people from each and every grade so this would represent the percentage occur from each grade this determine the number of people who vote per grade and represent that how much would the vote for student comes
Also 50 is easily divisible by 750
Therefore the above represent the answer
Answer:
p = 8000 + 2(6000)
20000
Step-by-step explanation:
Given that:
Profit in 1988 = 6000
Profit in 2003 = 8000 more Than double the profit made in 1998
Hence profit in 2003 (p) can be expressed as :
p = 8000 + 2(6000)
Hence profit in 2003
p = 8000 + 12000
p = 20,000
