Answer: Solving for x
Step-by-step explanation:
First add the known variables. This gets you 3.2
Next, since you know that multiplication is used to find 6.4 we take the inverse. 6.4/3.2
To get 2.
And finally, check you work.Fill in the x value and substitute for x. .9(2) + 2.3(2) to make sure your division is correct.
Hope this helps!!
Answer:
-2
0.9x + 2.3x = -6.4
3.2x = -6.4
x = -2
The answer is 144,5
144,5/170×100 =85%
n < 27
let the number be n
cos 225 = -cos 45 = -1/√2.
sin 225 = -sin45 = -1√2.
