There were 200 students that attend the dance.
Answer: They have to sell 21 t-shirts to reach their goal.
T-shirt: $5
Goal: $150
$45 has been raised so far (that means they sold 9 T-shirts) 5 x 9 = $45
150/5 = 30 t-shirts (they need to sell 30 t-shirts in the total)
150-45 = They need $105 to archive their goal
105/5 = 21 t-shirts
Step-by-step explanation:
If Q is the midpoint of PR
Then PQ + QR = PR
(6x + 25) + (16 - 3x)
group the same terms and add them
(6x - 3x) + (25 + 16)
Hence PR = (3x + 41)
But to find the value of PR....If Q is the midpoint....then PQ = QR...since they are both half lengths of PR;
; 6x + 25 = 16 - 3x
; 6x + 3x = 16 - 25...;9x = -9
Hence the value of...x = -1
Then substitute the value of x into the equation of PR....3x + 41
;3(-1) + 41
;-3 + 41
Hence PR = 38
