Answer:
Equivalent of 7/8 are 14/16,21/24, 28/32, 35/40,..........
C= cat d=dog
(7+c) + d =45
-7 -7
c+d= 38/2 = 19
so there are 19 dogs and 26 cats (19+7)
2/3(12c-9)+14c
Simplify
2/3•3(4c-3)+14c
=2(4c-3)+14c
=8c-6+14c
Combine
=22c-6
=2(11c-3)
Answer:
8 bags.
Step-by-step explanation:
Each bag will contain 27/3 = 9 pounds of quartz and 21/3 = 7 pounds of marble.
So there are 72/ 9 = 8 bags which contain 72 pounds of quartz. They will contain 56 pounds of marble, not 52 pounds.
