This question requires creating a few equations and working through them step-by-step. Now, first let's give each of the shapes a variable: let's say that the blue shape is a, the orange shape is b and the green shape is c.

1. We can technically create six formulas for the magic square, with three for sum of the rows and three for the sum of the columns, however the smartest way to approach this is to observe whether there are any obvious answers that we can get.

We can see in row 2 that there are three of the same shape (a) that add to 57. This makes it very simple to calculate the value of the shape.

Since 3a = 57

a = 57/3 = 19

2. Now we need to find a row or column that includes a and one other shape; we could choose either column 2 or 3, so let's go with column 2. Remembering that the blue shape is a and the orange shape is b:

2a + b = 50

Now, given that a = 19:

2(19) + b = 50

38 + b = 50

b = 12

3. We can now take any of the rows or columns that include the third shape (c) since we already know the values of the other two shapes. Let's take column 1:

a + b + c = 38

19 + 12 + c = 38

31 + c = 38

c = 38 - 31

c = 7

Thus, the value of the blue shape is 19, the value of the orange shape is 12 and the value of the green shape is 7.

Question 6 of 10
Crank

Answer:

A, D

Step-by-step explanation:

When solving for x, we want to get all x terms on one side and all non-x terms on the other side. To make it so that x is by itself, we need to get rid of -3. We can do this by adding 3 to both sides, which demonstrates the addition property of equality. This property states that if you add a quantity to one side of an equation, you must add the same quantity to the other side as well.

Hi Timothy,


1. Write a rule for the sequence.

8, -1, -10, -19...

A. Start with 8 and add -9 repeatedly

B. star with -9 and add 8 repeatedly

C. start with 8 and add 9 repeatedly

D. start with 8 and subtract -9 repeatedly---

Answer - So you have to start with -9 then keep subtracting 9. Thats what I think the answer is but the answer is not stated in the question. Let me know on what that is. The closest answer is probably either B or D.


2. find the next three terms of the sequence.

-6, -24, -96, -384

1) -768, -1536 , -3072

2) -768, -3072, -12288

3) -1536, -6144 , -24567

4) -1536, -9216, -36864

The rule is multiplying by 4!

So the correct answer is 3) -1536, -6144 , -24567
