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
What is the question you are trying to ask
0.3:0.1
Step-by-step explanation:
first convert the % to decimals.
75%=0.75
25%=0.25
then look for a common factor and divide be that, in this case its 5.
0.75/5=0.15
0.25/5=0.5
now since these arent in the simplified form, you gotta divide again by 5.
0.15/5=0.3
0.5/5=0.1
Simultaneous Equations
2s + 3f = 41
3s + 2f = 44
(x2) 4s + 6f = 82
(x3) 9s + 6f = 132
'If the signs are the same, subtract'
4s - 9s = -5s
82 - 132 = -50
-5s = -50 Therefore s = 10
Now, substitute back into the equation
(2 x 10) + 3f = 41
20 + 3f = 41
Balance the equation: subtract 20 from both sides
41 - 20 = 21
3f = 21
3f/3 = f
21/3 = 7
f = 7
s + f = x
10 + 7 = 17 pounds
