How many units long is a segment whose endpoints are (2,3) and (7,15)?

Mathematics

Ahat [919]3 years ago
5 0

Answer:

13 units

Step-by-step explanation:

Distance formula: d = \sqrt{(x2-x1)^2 + (y2-y1)^2}

Simply plug in your variables

d = \sqrt{(7-2)^2 + (15-3)^2}

d = \sqrt{5^2 + 12^2}

d = \sqrt{25 + 144}

d = \sqrt{169}

d = 13

How do I solve this?<br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B3x%7D%7B8%7D%20%20-%201%20%3D%20%20%5Cfrac%7B5%7D%7B8%7D%

To solve this problem, we first have to combine the two fractions on the left side of the equation.  To do this, we must make a common denominator of 8.  Because 8/8 is equal to 1, we can substitute this value into the equation:

3x/8 - 8/8 = 5/8

Next, we can subtract the fractions on the left side of the equation to simplify.  Remember that if fractions have the same denominator, we simply subtract their numerators and keep the difference over the common denominator.

3x - 8/8 = 5/8

Since both sides of the equation have a denominator of 8, we can cancel out this denominator on both sides by multiplying both sides by 8.  This gives us:

3x - 8 = 5

Next, we should add 8 to both sides of the equation so that we can get all of the constants to the right side of the equation.

3x = 13

Finally, we should divide both sides by 3 to get the variable alone on the left side of the equation.

x = 13/3

Therefore, your answer is x = 13/3.

Hope this helps!

Answer:

x = 125

Step-by-step explanation:

all of the angles in a triangle must add up to 180, so 25 + 30 + x = 180. you can subtract 25 and 30 from both sides and you are left with x = 125.

hope it helps!
