Answer:
Step-by-step explanation:
Lets say there's a number 'x' and there's an expression where 'a' & 'b' are also numbers , <u>the simplified form of the expression is </u><u>.</u>
So ,
Basically, the question is asking, what will happen if we increase 9 by 30%?
first, what is 30% of 9?
So, the increase will be by 2.7 days,
So the total amount will be 9+2.7=11.7 - this is the correct answer.
Answer:
x = 3.4
y = 1.4
Step-by-step explanation:
2x + 3y = 11
2y = 13 – 3x, then y = (13 - 3x)/2
substitute for y:
2x + 3((13 - 3x)/2) = 11
reduce:
2x + (39 - 9x)/2 = 11
reduce:
2x + 19.5 - 4.5x = 11
subtract 19.5 from both sides of the equation and combine for x:
-2.5x = -8.5
divide both sides by -2.5:
x = 3.4
y = (13 - 3(3.4))/2 = (13 - 10.2)2 = 1.4
