Answer:
x = 36 , 2x = 72 , 3x = 108 , 4x = 144
Step-by-step explanation:
2x = P+Q (ΔABC, exterior angle property)
4x = R+S (ΔDBC, exterior angle property)
4x + 2x = P+Q+R+S = (P+R) + (Q+S) = (180 - 3x) + (180 -x) (supplementary)
6x = 360 - 4x
10x = 360
x = 36
2x = 72
3x = 108
4x = 144
check: sum of interior angles = (180 x 4) - (36+72+108+144) = 360
She bought 2 fancy shirts and 5 plain shirts.
2 x 28=$56, and 5x15=$75. 75 plus 56 is 131
One rule of logs is when you add logs, u can combine the parentheses by multiplying so..
log(10a) + log(100a)
log(10a × 100a). now multiply
log(1000a^2)

20% of 500 is 100, so take 100 off 500, which is 400. So, $400.
