Answer:
c = -400
Step-by-step explanation:
-2/5c -8 = 32
-2/5c = 40 add 8 to both sides
c = -400 multiply both sides by the opposite reciprocal, -5/2
210 yd³
V=LWH
V=(8 1/3)(4 1/5)(6)
V=(25/3)(21/5)(6)
V=(525/15)(6)
V=3150/15
V=210
Therefore, the volume of the prism is 210 yd³
15x +30y -220
steps:
30(1/2x-2)+40(3/4y-4)
= 15x-60 +30y-160
= 15x +30y -220
