Answer:
x is a variable, it can be ANY NUMBER
Step-by-step explanation:
Answer:
H = 58, I = 71, J = 51
Step-by-step explanation:
Set all angles equal to 180
3x - 2 + 4x - 9 + 3x - 9 = 180
Then combine like terms
10x - 20 = 180
+ 20 + 20
10x = 200
/10 /10
x = 20
Then plug in for each angle
3 (20) - 2 = 58
4 (20) - 9 = 71
3 (20) - 9 = 51
Answer: n + 2 = 2n
Step-by-step explanation:
sum = add
number and two = n, 2
twice the number = 2 x n
($3756/100)(100+12)/100
$37.56(1.12)
$42.0672
$42.07 (to nearest cent)
The number 2852.1 is already rounded to the tenth since the tenth place is one place to the right of the decimal
