A. 5x – 2 + 2 = 2 - 4 B.
5x +2 = 2-4
1) How can we get Equation B from Equation A?
Choose 1
А
Add/subtract a quantity to/from only one side
B
Add/subtract the same quantity to/from both sides
Rewrite one side (or both) using the distributive property

sorry i just need to anwers this to get points

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

stock holders gave company a contract to lay tack to 2 to 3 times actual cost and pocketed profits

-took $23 mill in stocks
