Answer:

n = 0

Step-by-step explanation:

Multiply parenthesis by 3 and get:

1.) 18 + 9n = 5n + 18 + 3n

Then cancel the equal terms:

9n = 5n + 3n

Collect like terms:

9n = 8n

Move variable to the left:

9n - 8n = 0

n + 0

Plugin the value of 0 into x:

3 (6 + 3 x 0) = 18

5 x 0 + 3 x 0 + 18 = 18

*If the plugged in value have the same result than the answer is correct because 18 + 18.

Burka [1]

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

Samir harvest the peppers and pumpkins in his garden he picks 3 5/8 less peppers in the afternoon than in the evening if Samir p
tatuchka [14]
<h2>Hello!</h2>

The answer is:

Samir picks 7\frac{9}{8} Kg of peppers in the evening.

<h2>Why?</h2>

To solve this problem, we must remember the way to add or subtract mixed numbers.

We must remember the way of adding or subtracting fractions:

\frac{a}{b}+\frac{c}{d} =\frac{ad+bc}{bd}

Also, if we need to add or subtract mixed numbers with different denominators, we need to follow the next steps:

- Add or subtract the whole number part

- Add or subtract the fractional numbers.

- Put together both, whole number addition or subtraction result and the addition or subtraction of the fractional numbers.

So,

a\frac{b}{c}+d\frac{e}{f} =(a+d)\frac{bf+ce}{cf}

Now, if Samir picks 3 5/8 less peppers in the afternoon than in the evenning, and if he picks 4 3/6 peppers in the afternoon, so:

Let be x the number of peppers that he picks in the evening, so:

x-3\frac{5}{8}x=4\frac{3}{6}\\\\x=4\frac{3}{6}+3\frac{5}{8}

Then, simplifying we have:

x=4\frac{3}{6}+3\frac{5}{8}\\\\x=4\frac{3}{6}+3\frac{5}{8}=(4+3)\frac{24+30}{48}\\\\x=(4+3)\frac{24+30}{48}=7\frac{54}{48}=7\frac{9}{8}

So, Samir picks 7\frac{9}{8} Kg of peppers in the evening.

Have a nice day!
