Secondly:
Given that a♥b = 2a(32− b)
If a♥b = −23, solve for b in terms of a.
A) b = 16a + 32
B) b = 13a + 32
C) b = 12a + 32
D) b = 16a − 32
</span>-23 = 2a(32− b), devide both sides by 2a -23/2a = 32 - b, subtract 32 from both sides -23/2a - 32 = -b, multiply both sides by -1 23/2a + 32 = b
verified:
b = 23/2a + 32
-23 = 2a(32 − (23/2a + 32))
-23 = 2a(32 -23/2a -32)
-23 = 2a(-23/2a)
-23 = -23

Answer:
80 hours for 2 workers to build 8 cars
Step-by-step explanation:
2 cars / 8w *5 hr = 2 cars / 40 hrs 1 car takes 20 hrs
8 cars * 20 hours = 160 hours required
two workers split this time 160/2 = 80 hours
This would equal 54 because 5.4x10^2 is 54
Answer:
Step-by-step explanation:
-(x + y) = (-x) + (-y)
-(3/4 + 2/5) = (-3/4) + (-2/5)
-(15/20 + 8/20) = (-15/20) + (-8/20)
-(23/20) = -15/20 - 8/20
-23/20 = -23/20
