Answer:
6.5 * 10 ^ -9
Step-by-step explanation:
0.0000000065
Scientific notation means a* 10 ^b
where a is number between 1 and less than 10
Move the decimal 9 places to the right which means the power of 10 is negative since we moved the decimal to the right
6.5
The power of 10 is -9
6.5 * 10 ^ -9
In decimal form the answer is 20.34375
(1/4)*(4*x+15) = 24 // - 24
(1/4)*(4*x+15)-24 = 0
1/4*(4*x+15)-24 = 0
1/4*(4*x+15)-24 = 0
x-81/4 = 0
x-81/4 = 0
x-81/4 = 0 // + 81/4
x = 81/4
x = 81/4
