Will brainlist!!! 21 and 22 form a linear pair.
If mZ1 = (5x + 9) and mZ2 = (3x + 11)", find m21.
mZ1 = 71°
m21 = 109°
mZ1 = 70°
m21 = 110°

Jamie went to home depot.she bought 25 bags of soil that cost $9 per bag.she bought 15 pots at $8 each,and she bought 23 bags of pebbles at $15 each.she used a coupon that gave her $5 off for every 100 dollars she spent.how much did jame pay at the end?
