Answer:

Step-by-step explanation:

Let s and a represent the numbers of student and adult tickets sold. The system of equations that can be written from the given information is ...

  s + a = 250 . . . . . . total of tickets sold

  3s +5a = 1050 . . . dollar value of tickets sold

_____

The solution is (s, a) = (100, 150). 100 student tickets and 150 adult tickets were sold.

Answer:

  J  3/4 cup

Step-by-step explanation:

Step 1: read and understand the question.

  The question is giving you amounts of flour and 2 types of sugar.

  The question is asking for a difference between two quantities:

Step 2: determine the relations you need to use to solve the problem

   You need the combined amount of sugar, which you find by adding the quantities of each of the kinds.

  3/4 cup white + 3/4 cup brown = 6/4 cup sugar combined

 You need the difference of that quantity from the quantity of flour, which you find by performing subtraction:

  flour - sugar = (2 1/4) - (6/4) . . . . cups

Step 3: Use your knowledge of arithmetic.

  (2 1/4) -(6/4) = 9/4 -6/4 = (9 -6)/4 = 3/4

Step 4: Answer the question that was asked.

  The difference between the flour and sugar amounts is 3/4 cup.

Answer:

Each egg is $5 so 4 dozen(48) is $240

Step-by-step explanation:

the way to do this is 75/15= 5

and then you multiply 12 x 4 to get 48 eggs

and then multiply 48 x 5 to get $240

15:75

divide each by 5

3:15

(4 dozen is 48 -> 48/3 = 16)

multiply each by 16

48: 240

Answer:

a=3 x= all reals

Step-by-step explanation:

I actually did not get 6 for an answer

4x+a=4x+3

cancel equal terms on both sides of the equation

a=3  

which means the x would be all reals cause it is true.

Irene offered answer equivalent to the original expression

Given :

Mrs. Crosland asked students to factor the expression 28x - 8

The student are given some expression . To find correct expression , we need to factor the given expression

[tex]28x-8[/tex]

Both 28 and 8 are divisible by 4

Lets factor out 4 from the given expression.

When we factor out 4, then we divide each term by 4

[tex]28x-8\\4(\frac{28}{4} -\frac{8}{4} )\\4(7x-2)[/tex]

The students offered the answers shown

Carlos: 2(14x - 4)

Danny: 7(4x - 1)

Irene: 4(7x - 2)

so , from the answer we can say that Irene offered answer equivalent to the original expression

Answer:

8

Step-by-step explanation:

You know that the horizontal lines are parallel to each other.

The 8 and x is both on that diagonal right there. Since the horizontal lines are parallel, that means the angle of 8 should have the same angle as x.

I think the answer is -72. I'm not very sure, but I solved the equation the way I understood it, and I got -72.

Answer:

∠ABC = 54°

Step-by-step explanation:

an inscribed angle is 1/2 the size of an incenter angle.

so:

∠AMC = 2(∠ABC)

10x - 12 = 2(4x + 6)

10x - 12 = 8x + 12

simplify:

2x = 24

x = 12

∠ABC = 4(12) + 6 = 54°
