The distance between the first and last plant is .
Further explanation:
Given:
A farmer is planting a straight row of crops with 3 feet between each plant.
Calculation:
Consider the number of plant as .
The number of spaces between the plants is calculated as follows:
……(1).
Since, the number of plants are 23, Substitute 23 for in equation (1) to obtain the number of spaces between the plants.
Since, the distance between each plant is 3 feet, the distance between the first and last plant is calculated as follows:
……(2)
Substitute 22 for in equation (2) to obtain distance
between the first and last plant.
Thus, the distance between the first and last plant is .

Final answer:
The distance between the first and last plant in a straight row of 23 crops with a spacing of 3 feet each is 66 feet. This is calculated using the formula: (Number of plants - 1) * Distance between plants.
Explanation:
The problem requires you to find the total distance from the first to the last plant in a row of crops considering that each plant is planted 3 feet apart. This type of problem can be solved by simple arithmetic calculations.
You might think you should simply multiply the number of plants by the distance between them, but this would not provide the correct answer. The reason is that the distance between the plants is not the same as the distance from the first to last plant.
For example, if the farmer only planted two crops, there would only be 3 feet between them, not 6. Therefore, we need to use the formula: (Number of plants - 1) * Distance between plants.
To solve for our question, we’d get: (23 plants - 1) * 3 feet = 66 feet. Thus, the distance between the first and last plant is 66 feet.

1. Distribute the 2 on the left side of the equation to both terms inside the parentheses:
2x + 6 = x - 4
2. Now, let's isolate x on one side of the equation. You can do this by subtracting x from both sides:
2x - x + 6 = -4
3. Simplify the left side by combining like terms (2x - x):
x + 6 = -4
4. To isolate x, subtract 6 from both sides of the equation:
x + 6 - 6 = -4 - 6
5. Simplify both sides:
x = -10
So, the solution to the equation is x = -10.

Hi
2x-y=5
3x+2y=4
We need to solve 2x-y=5 for y
Now let's start by adding -2x to both sides
2x-y-2x=5-2x
-y=-2x+5
Divide both sides by -1 so we eliminate the negative sign
-y/-1=-2x+5/-1
y=2x-5
Now substitute 2x-5 for y in 3x+2y=4
3x+2y=4
3x+2(2x-5)=4
3x+4x-10=4
7x-10=4
Add 10 to both sides
7x-10+10=4+10
7x=14
Divide both sides by 7 so we can find the value for x
7x/7=14/7
x=2
Now substitute 2 for x in y=2x-5 so we can find the value for y
y=2x-5
y=(2)(2)-5
y=4-5
y=-1
