Use rhombus tqrs to answer the question.

3. what is the value of x?
a. 2
b. 1
c. 5
d. 4

4. what is the value of y?
a. 4
b. 3
c. 2
d. 1

B and A

Step-by-step explanation:

The diagonals of a rhombus bisect each other at right angles, thus

(3)

y = x + 3 → (1)

3x + 2 = y + 1 → (2)

Substitute y = x + 3 into (2)

3x + 2 = x + 3 + 1

3x + 2 = x + 4 ( subtract x from both sides )

2x + 2 = 4 ( subtract 2 from both sides )

2x = 2 ( divide both sides by 2 )

x = 1 → B

(4)

Substitute x = 1 into (1)

y = 1 + 3 = 4 → A

Part A: Write an expression that Robie can use to determine how much black pepper is needed for 6 batches.
 The first thing you should know in this case is the amount of pepper available and the amount of black pepper in each batches.
 Available = s 2/3 teaspoon
 Batches = 1/8 teaspoon
 Let
 x = number of batches:
 y = black pepper
 The expression is then:
 y = 1/8x
 0 <= x <= 6
 ---
 Part B: Draw a Model to show how Robbie can find the product from Part A (do not say how to draw the model just say how to solve the expression in Part A.)
 You must graph the line of part A:
 y = 1/8x
 Then, check for x = 6 the value of y to know how much black pepper is needed for 6 batches.
 
 Part C: Does Robbie have enough black pepper for 6 batches of the soup? Explain your reasoning. (<--- PLEASE EXPLAIN.) 
 Substituting x = 6
 y = 1/8 (6)
 y = 6/8
 y = 3/4
 3/4> 2/3
 Robbie has not enough black pepper for 6 batches of the soup
