What is the question now??
This time you have to plug in the 62.10 to the P and solve for x.
I know that the new equation is now<span>62.10=(20+0.5x)+0.15(20+0.5x)
</span>okay so, x equal 68, the number of pages .
Answer:
x = (1/2) (-9 ± √73)
Step-by-step explanation:
Using completing the square method
x²+9x+2=0
x²+9x = -2 (complete the square by adding (9/2)² to both sides)
x²+9x + (9/2)² = -2 + (9/2)²
( x + (9/2) )² = -2+ (9/2)²
( x + (9/2) )² = -2+ (81/4)
( x + (9/2) )² = 73/4
x + (9/2) = ± √(73/4)
x + (9/2) = ± √(73) / 2
x = -(9/2) ± √(73) / 2 (factorize out (1/2) )
x = (1/2) (-9 ± √73)
Number of tickets= X
To find the number of tickets, divide the money Jan has with the cost of each ticket.
So,
X =37.50/ 5.25=7.14
But since she can't buy part of a ticket, Jan can buy 7 tickets
Answer: -9 degrees Celsius
Step-by-step explanation: You subtract two degrees from -3 and get -5 (-3-2=-5). Then, you subtract 4 degrees from -5 and get the answer of -9 degrees Celsius.
