Gary is baking pretzels for his sister’s party. some pretzels will be regular and some pretzels will be whole grain.
let x represent the number of dozens of regular pretzels.
let y represent the number of dozens of whole-grain pretzels.
gary needs to bake at least 14 dozen pretzels in all.
gary has 20 cups of flour. he needs 2 cups of flour for each batch of 12 whole-grain pretzels and 1 cup of flour for each batch of 12 regular pretzels.
select the constraints that correctly model the inequality

The constraints are

Step-by-step explanation:

Let

x-------> the number of dozens of regular pretzels.

y-------> the number of dozens of whole-grain pretzels.

we know that

--------> inequality A

-------> inequality B

-------> inequality C  (cannot be a negative number)

------> inequality D  (cannot be a negative number)

The solution is the triangular shaded area

see the attached figure

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or
