Make x the subject of these equations.
shepuryov [24]

(1)a(x + b) = c \\ ax + ab = c \\ ax = c - ab \\  \frac{ax}{a } =  \frac{c - ab}{a}   \\ x =  \frac{c - ab}{a}

(2)8(x + a) = b \\ 8x + 8a = b \\ 8x = b - 8a \\  \frac{8x}{8}  =  \frac{b - 8a}{8}  \\ x =  \frac{b - 8a}{8}

(3)a(x - 7) = b \\ ax - 7a = b \\ ax = b + 7a \\  \frac{ax}{a}  =  \frac{b + 7a}{a}  \\ x =  \frac{b + 7a}{a}

(4)c(2  + x) = 6 \\ 2c + cx = 6 \\ cx = 6 - 2c \\  \frac{cx}{c}  =  \frac{6 - 2c}{c}  \\ x =  \frac{6 - 2c}{c}

What is the difference of 1 and 0.1978
Marina CMI [18]

Answer: 0.8022 | This is your answer

Step-by-step explanation:

Well this question is a bit baud but I will try to answer my best.

To find the difference of any number you just need to subtract.  

So a-b=c   |  c is your difference.

So in this problem 1-0.1978 would equal 0.8022
