34% . <span>Since going from 75% to 82% is simply the right portion of that middle, the answer is half of 68%, or 34%.</span>
We know the total tickets sold = 400.
Let x be the number of adult tickets sold.
That means 400 - x is the number of student tickets.
The revenue from adult tickets will be $3 * x, which we can call 3x.
The revenue from student ticks will be $2 * (400 - x), or 800 - 2x.
The total revenue is $1050, so that means:
3x + (800 - 2x) = 1050.
Removing the parentheses:
3x + 800 - 2x = 1050
Subtracting 800 from both sides:
3x - 2x = 250
Simplifying the left side:
x = 250, which is the number of adult tickets.
400-x = student tickets = 400-250 = 150.
ALWAYS check!
In this case, check the revenue:
3x = 3(250) = 750
2(150) = 300
750 + 300 = 1050. Check!
Answer:
b. -13
Step-by-step explanation:
The change in temperature will be the original temperature plus or minus x, the change between a temp and b temp, to equal what the temperature is now.
Answer:
B
Step-by-step explanation:
3 out of 10 is smaller than 3 out of 5
(−5)(2)−2(−3)+3 ( -5 )( 2 ) - 2 ( -3 ) + 3
=-10+6-30+6+3
=15-40
=-25
