The cost for one lemon is $0.75.
(7a-b+3)-(-2a-8b+8)
Apply plus/minus rule.
-(-a)= a and -(a)=-a
we get
(7a-b+3)-(-2a-8b+8)= 7a-b+3+2a+8b-8
Add like terms
=9a+7b-5
Answer: 9a + 7b - 5
Answer:
The correct option is A.
Step-by-step explanation:
The general exponential growth model is defined as
Where, a is initial value, r is growth rate and x is time.
The initial population of town is 9800 and growth rate is 2%. The population growth model is defined as
Put x=7 to find the estimated population after 7 years.
Therefore the correct option is A.
Answer:
200
Step-by-step explanation:
There are 6 numbers on a standard number cube. If the rolling is random, there should be a 1/6 chance of rolling a certain number. Basically, someone would theoretically roll each number 100 times out of 600. Because there are two numbers on the dice greater than 4, multiply 100 by 2 to find the answer.
A. 2/3x=6
B. I chose multiplication because division would be used to find the answer without an equation so I chose the inverse (or opposite) operation
