Answer:

X=3

Step-by-step explanation:

Equation 1:

7×3=21

21+18=39

Equation 2:

10×3=30

30+9=39

If you replace x with 3 on both equations then you get 39 and if you get 39 on both equations that means it is equal.

The inequality that models this situation is 150x + 350 y ≤ 250000 and x + y < 1200

<h3>What is an inequality?</h3>

An inequality is an expression that shows the non equal comparison of two or more numbers and variables.

Let x represent the number of wheat acres and y represent the number of corn acres, hence:

150x + 350 y ≤ 250000     (1)

Also:

x + y < 1200     (2)

The inequality that models this situation is 150x + 350 y ≤ 250000 and x + y < 1200

polet [3.4K]
For this case what we can do first is to take an average of the number of cars.
 We have then:
 P = (12 + 18 + 24) / (3)
 P = 18
 In other words, you can organize your cars in rows of 3 where each row will have 18 cars.
 Answer:
 three rows, 18 cars per row.

To find the mean:

Take <span>3 4 5 3 4 5 6 5 4 3 2 3 4 5 6 4 8 4 3 2 and add them all together

=83

Now you divide 83 by the number of terms in the sample set, which is 20. 

83/20 = 4.15

For rounding to the nearest tenth, look at the hundredths space, which is 5. Since it is 5 or higher, round the tenths up one.
