Answer:

In a very simple way, it can be verified that the equation is correct by making the divisions that the fractions represent, and checking that the result of these divisions is the same, as presented by the equation.

That is, by making the division of 1/2 and adding it to the division of 3/8, the result of said sum should be equal to 4/10 and 2/5.

Therefore, I will perform this calculation to verify if the equation is correct:

1/2+3/8 =4/10=2/5

0.5 + 0.375 = 0.4

0.875 = 0.4

As we can see, the equation is absolutely false, since the sum of 1/2 + 3/8 does not result in 4/10 or 2/5 (which are the same fraction, but simplified) but 7/8 (7 / 8 = 0.875).

9 stores is 3% of how many stores?

hichkok12 [17]

Hello there! We can solve this question by writing and solving a proportion. Set it up like this:

9/x = 3/100.

This is because 9 is 3% of x number of stores and percents are parts of 100. Setting it up like this will help us get the correct answer. Cross multiply the values . 9 * 100 is 900 and 3 * x = 3x. You get 900 = 3x. Now, divide each side by 3 to isolate the x. 3x/3 cancels out the x. 900/3 is 300. There. x = 300. 9 stores is 3% of 300 stores.

North divided by Total (Total of North, South, Central, East, and West)

North = 1

South = 4

Central = 2

East = 3

West = 2

North ÷ Total

1 ÷ (1 + 4 + 2 + 3 + 2 )

1 ÷ (12)

= $\frac{1}{12}$

Answer:

$x < 80000$

Step-by-step explanation:

$3600 + 1.02x < 2000 + 1.04x \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: \: - 1.04x < \: \: \: \: \: \: \: \: \: \: \: \: \: - 1.04x}{3600 - 0.02x < 2000} \\ \\ 3600 - 0.02x < 2000 \\ \frac{ - 3600 \: \: \: \: \: \: \: \: \: < - 3600}{ - 0.02x < - 1600} \\ \\ \frac{ - 0.02x}{ - 0.02} < \frac{ - 1600}{ - 0.02} \\ \\ x < 80000$
