Answer:
Let B = the weight of box B
Let 2B = the weight of box A
Let 2B + 30 = the weight of box C
B + 2B + 2B + 30 = 640
5B = 610
B = 122 pounds, weight of box B
2B = 2(122) = 244 pounds, weight of box A
2B + 30 = 2(122) + 30 = 274 pounds, weight of box C

8 x 64
= 8 x ( 60 + 4 )
= 8 x ( 6 x 10 + 4 )
= 8 x 6 x 10 + 8 x 4
= 48 x 10 + 32
= 480 + 32
= 480 + 20 + 12
= 500 + 12
= 512
Answer:
△QPR ≅ △TSU
Step-by-step explanation:Remember, they always look the same, so if △QPR ≅ △STU, it won't work because they are not identical anymore. For example, if you do △ABC ≅ △ABC, △BCA is not the exact same as △CAB. I hope this helps you!
