Question 1:
<span>5z – 9 = 36
5z = 45
z = </span>
z = 9
Hence, the answer is D.
Question 2:
<span>5(2z + 4) = 0
</span><span>
10z + 20 = 0
10z = -20
z = </span>
<span>
z = -2
Hence, the answer is A.
Question 3:
4a + 3(a + 1) = 24
4a + 3a + 3 = 24
7a = 21
a = </span>
a = 3
Hence, the answer is B.
Question 4:
<span>3(4x + 5) = 12
12x + 15 = 12
12x = 12 - 15
12x = -3
x = </span>

Answer:
Option B) 18 is the correct answer.
Step-by-step explanation:
Let n(A) be the shoppers who purchased at an online store
Let n(B) be the shoppers who purchased at a locally-owned store
Let n(C) be the shoppers who purchased at a big-box store
n(A ∩ B) is the shoppers who purchased at an online store and at a locally-owned store
n(B ∩ C) be the shoppers who purchased at a locally-owned store and at a big-box store
n(C ∩ A) is the shoppers who purchased at an online store and at a locally-owned store and at an online store
From the Venn diagram,
n(A) = 109
n(B) = 34
n(C) = 107
n() = 38
n(B ∩ C) = 17
n(C ∩ A) = 57
On Comparing the Venn Diagrams, we could find that shoppers made a purchase at an online store, a locally-owned store, and a big-box store [n( A ∩ B∩ C)] = 18
