Answer:
x = 13.444 ... (repeating decimal) or;
x = 13 4/9
Step-by-step explanation:
-0.65 + 0.45x = 5.4
First we will add 0.65 to each 'side' of the equation.
0.65 + (-0.65) + 0.45x = 0.65 + 5.4
0.65 + (-0.65) = 0
0.65 + 5.4 = 6.05
Input the numbers, and now the equation looks like this:
0 + 0.45x = 6.05
Remove the zero:
0.45x = 6.05
Divide each 'side' by 0.45.
0.45x ÷ 0.45 = 6.05 ÷ 0.45
0.45x ÷ 0.45 = 1x = x
6.05 ÷ 0.45 = 13.444 ... repeating decimal
Input the numbers, and now the equation looks like this:
x = 13.444 ... repeating decimal
We can also write this as:
x = 13 4/9 in fraction form
Answer:
add all the angles and equal with 180°
Answer:
a) 17
b) 45
Step-by-step explanation:
a) 
use pemdas first,
= 4
3x4 = 12
1x4 = 4
now the equation is 
9+12 = 21
that makes the equation 21-4
21-4 = 17
a) 17
now for b
b)
the equation would then be 
so youd use pemdas as always
start in the parenthases
= 4
4-1 = 3
the equation is now 
now, multiply 3x3x4
3x3 = 9
9x4 = 36
now the equation is 9+36
9+36 is 45
b) 45
hope this helped!
