Using the Pythagorean Theorem, we have that the distance from home plate to second base is about 127 feet.

<h3>What is the Pythagorean Theorem?</h3>

The Pythagorean Theorem relates the length of the legs l_1 and l_2 of a right triangle with the length of the hypotenuse h, stating that the hypotenuse squared is the <u>sum of the legs squared</u> of the triangle, according to the following equation:

h^2 = l_1^2 + l_2^2

The distance between each consecutive base is of 90 feet, hence the distance from home plate to 2nd base is the hypotenuse of a <u>right triangle in which the legs are of 90 feet</u>, being the distances from home plate to 1st base and 1st base to 2nd base.

Then:

h² = 90² + 90²

h = sqrt(90² + 90²)

h = 127 feet.

The distance from home plate to second base is about 127 feet.

-15 + 12x = 5x + 7 -3x<br> SOLVE FOR X
Natali [406]

Answer: x=\frac{11}{5}

<u>Simplify both sides of the equation</u>

<u></u>-15+12x=5x+7+-3x<u></u>

<u></u>12x-15=(5x+-3x)+(7) (Combine Like Terms)

12x-15=2x+7

<u>Subtract 2x from both sides</u>

<u></u>12x-15-2x=2x+7-2x\\10x-15=7<u></u>

<u></u>

<u>Divide both sides by 10</u>

<u></u>\frac{10x}{10} =\frac{22}{10}<u></u>

<u></u>x=\frac{11}{5}<u></u>

<u></u>
