X2, or 2X or X times 2, or X•2.
using pythagorean theorem
a^2 + b^2 = c^2
(12x)^2 + (16x)^2 = 10^2
square each term
144x^2 + 256x^2 = 100
combine like terms
400 x^2 = 100
divide by 400 on each side
x^2 = 1/4
take the square root on each side
x = 1/2
Answer: x=1/2
Answer:
20
Step-by-step explanation:
make a # bar and market up as a percentage do 25%, 50%, 75% then you put 15 where 75% is and from there you see where the #'s fit
Answer:
- given
- additive property of equality
- segment addition postulate
- segment addition postulate
- transitive property
Step-by-step explanation:
In an equation, the additive property of equality states that if we add or subtract the same number to both sides of an equation, the sides remain equal.
transitive property, If a = b and b = c, then a = c.
Segment Addition Postulate Defined. The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation AB + BC = AC.
