The answer to this is 4 ≤ x

In order to find this, follow the order of operations.

−7 ≥ 13 − 5x ----> Subtract 13 from both sides

-20 ≥ -5x -----> Divide by -5

4 ≤ x (NOTE: the sign changes direction when dividing by a negative.

<u>Solve for x:</u>

−7 ≥ 13 − 5x

<u>Let's solve your inequality step-by-step.</u>

−7 ≥ 13 − 5x

<u>Step 1: Simplify both sides of the inequality.</u>

−7≥ − 5x + 13

<u>Step 2: Flip the equation.</u>

−5x + 13 ≤ −7

<u>Step 3: Subtract 13 from both sides.</u>

−5x + 13 − 13 ≤ − 7 − 13

−5x ≤ − 20

<u>Step 4: Divide both sides by -5.</u>

−5x/ −5 ≤ −20/ −5

x ≥ 4

<u>Answer: x ≥ 4</u>

Hope that helps!!! : )

How many plants x should she plant in each row so that her 25 plants end up in a square (i.e., x plants in each of x rows)? expr

AnnZ [28]

There are 5 plants x that should she plant in each row so that her 25 plants end up in a square (i.e., x plants in each of x rows)

<h3>Further explanation </h3>

Maria wants to plant a small tomato garden in her yard. She bought 25 tomato plants, and she has read that ideally tomatoes are planted in a square grid to help them pollinate each other, as shown in the picture below.

How many plants x should she plant in each row so that her 25 plants end up in a square (i.e., x plants in each of x rows)? Express your answer as an integer.

If the gardener has x plants in each of her x rows, then the total number of plants will be $x^2$ .

Since there are 25 total plants, the correct value of x will satisfy the equation $x^2 = 25$

By taking the square root of both sides and note that 25 has both a positive and a negative square root because you can't have a negative number of plants, hence you only want the positive square root:

You can solve this part simply by simple arithmetic.

$x^2 = 25,$ so $x = 5,$

On the blueprint of a house, 38 millimeters represents 6 meters. the length of the living room is 57 millimeters on the blueprin

Pie

For this case we can make the following rule of three:
38 milimeters ---------> 6 meters
57 milimeters ---------> x
Clearing x we have:
x = (57/38) * (6)
x = 9 meters
Answer:
the current length of the living room is:
x = 9 meters
