Each girl will get 4 tangerines
Answer:
B
Step-by-step explanation:
The zeros of a polynomial are the solutions to the function. They are found from the factors. The factors which multiply to make the equation in standard form. To write the factors reverse the process by unsolving the factor.
x = -2 comes from x+2
x = 5 comes from x-5
x = 6 comes from x-6
The factored form is (x+2)(x-5)(x-6).
An expression for the amount of money that Alicia earns in a day is 40y-3g.
Given that, Alicia runs a small business mowing yards in the summer. For every yard she mows, she earns $40. However, she spends part of this money on gasoline for her lawnmower. Each gallon of gasoline costs $3.
We need to find an expression for the given situation.
<h3>What is an expression?</h3>
In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Now, expression =40y-3g
Therefore, an expression for the amount of money that Alicia earns in a day is 40y-3g.

Answer:
There are 260 seats in economy class and 100 seats in business class
Step-by-step explanation:
To solve this problem we first have to calculate the fraction of economic and business seats with respect to the total
We are told that every 13 seats in economy class there are 5 seats in business class
13 + 5 = 18
This means that if there are 18 seats 13 will be economic and 5 business
economic seats = 13/18
business seats = 5/18
To find out the number of seats in the airplane of each class, we have to multiply the total number of seats by these fractions
economic seats = 360 * 13/18
economic seats = 260
business seats = 360 * 5/18
business seats = 100
