8y-6y^2/7^3
Answer:
2
Step-by-step explanation:
You count terms that are seperated by - and + signs. Any type of fraction is considered one term.
So you count 8y as one term and the rest is a whole fraction so you also count that as one term.
You add all the terms together and you have 2 terms in this equation.
Hope this helped :)
Answer: the number of cephalopods in her seashells collection is 26.
Step-by-step explanation:
Maria has a collection of 64 seashells consisting of three types bivalves,gastropods,and cephalopods. If 1/4 of her collection are bivalves, it means that the number of bivalves that she has is
1/4 × 64 = 14
If 3/8 of her collection are gastropods, it means that the number of gastropods in her collection is
3/8 × 64 = 24
Therefore, the number of cephalopods in her seashells collection is
64 - (14 + 24) = 26
Answer:
The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50
Step-by-step explanation:
Let,
x be the price per pound of walnuts
y be the price per pound of chocolate chips
According to given statement,
4x+8y=25 Eqn 1
2x+3y=10 Eqn 2
Multiplying Eqn 2 by 2
2(2x+3y=10)
4x+6y=20 Eqn 3
Subtracting Eqn 3 from Eqn 1
(4x+8y)-(4x+6y)=25-20
4x+8y-4x-6y=5
2y=5
Dividing both sides by 2
Putting y=2.50 in Eqn 2
2x+3(2.50)=10
2x+7.50=10
2x=10-7.50
2x=2.50
Dividing both sides by 2
Hence,
The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50
