Answer:
1.59
Step-by-step explanation:
log (2x-3)= log (3-x) -2
log (2x-3)/(3-x) =-2
If we remove log,
2x-3/(3-x) = e^-2
2x-3= 3e^-2 -xe^-2
2x+ xe^-2 = 3e^-2+3
x(2+e^-2) = 3( e^-2+1)
If you use calculator you will get answer nearly equal to 1.59.
Answer:
12
Step-by-step explanation:
let the missing number be x
8 + x * 4 = 56
8 + 4x = 56
4x = 56 - 8
4x = 48
x = 48/4
x = 12
therefore missing number is 12
the value of x is 20

Answer: 0.31
Step-by-step explanation:
7/22 is 0.31
5y-4 = 21
Add 4 on both sides to isolate y. (get rid of -4)
5y = 25
Divide 5 on both sides to solve for y.
y = 5
