Remark
If the lines are parallel then triangle RQS will be similar to triangle RTP
From that, all three lines in one triangle will bear the same ratio to all three lines of the second triangle.

PQ = 8
QR = 5
RS = 15
ST = x + 3
Ratio
QR/RP = RS/RT
Sub and solve
RP = 5 + 8
RP = 13
RT = 15 + x + 3
RT = 18 + x
5/13 = 15 / (18 + x) Cross multiply
5(18 + x) = 195 Remove the brackets on the left.
90 + 5x = 195 Subtract 90 from both sides.
5x = 105 Divide by 5
x = 105/5

9 times 52 = 468 hope that helped!!
Answer:
6 units
Step-by-step explanation:
count 6 units up
X = A/y
You divide the y from both sides
The y on the right cancels
On the left you have A/y = x
Answer: ln ( 40) *100
Step-by-step explanation:
Substituting 140 in the equation,
140 = 100 + e^(.01q)
40 = e^(.01q)
Take the natural log of bot hsides
ln ( 40) = .01q
q= ln ( 40 ) * 100
