Answer:
2.49
Step-by-step explanation:
57.27 / 23 = 2.49
Answer:
A) Canned and Packet
Grain, Meat and Vegetables
B) Let C = canned goods, let P = packet goods
20C + 7P
Let G = grain, let M = meat, let V = vegetables
7G + 3M + 17V
C) The number of grain and packet goods are the same in each expression, as this food group has been packaged in the same way.
The other variables in both expression are different. The meat and vegetable food groups have been separated in the second expression, whereas they are part of the same group in the first expression.
Twenty tables would be the answer
8²+9(12÷3×2)-7
well we are going to start in the parentheses and do order of operations
so 12÷3=4
then 4×2=8
so you have 8² +9(8)-7
well we still need to get rid of the parentheses 9×8=72
so then we are left with 8²=72-7
so now we have to get rid of the exponents so8²=64
64+72-7
136-7=129
so 129 is your answer to the first one.
the second one is easy. its a single step equation.
you are trying to get x by itself. so you have 7x=42. you want to get rid of the seven so you have to do the opposite of what it is doing to x. the 7 is multiplying by the x. So whats the opposite of multiplication... division. so you have to divide both sides by 7. so you have 7÷7x=42÷7
now simplify and you have x=6
3 tickets = $36
1 ticket = 36 ÷ 3 = $12
8 friends = $12 x 8 = $96
Answer: $96
