So you would do .39 times .39
that is .1521
If you round it is .152
.152 times 100 equals 15.2%
25/25 is equal to 1 whole. 3/4 x 1 is 3/4
3/4=?/100 : to get from 4 to 100 you x by 25. you then have to multiply 25 by 3 which gives you 75 which makes it 75/100 which can be simplified into 3/4
The laws of exponents that are often used in calculating values written in scientific notation are

, and

for example;

Answer: The value of x is 155/79.
Step-by-step explanation:
13(6x -5 )-x= 13 -2(x +1)
78x - 65- x = 13 -2x -2
77x -65 = 11-2x
79x -65 =11
79x =76
x = 76/79 76/ 79 + 1/1 = 155/79
Answer:
x=7
Step-by-step explanation:
write -2+16x+9x+7=180
then add all like terms (-2+7=5) and (16x+9x=25x)
5+25x=180
-5. -5
25x=175
/25. /25
x=7
