Answer:
x = 2
Step-by-step explanation:
all the angles in a triangle that are added together will equal 180 degrees
so having known that you will get this equation: \/
2x+5+8x=25
then you solve
8x+2x+5=25
10x+5=25
10x=20
x=2
A variable is a letter, for example x, y or z, that represents an unspecified number.
6 + x = 12
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
18*28/450=1.12
(1.12-1)*100=12%
Simple interest rate of the loan is 12%
