Answer:
2
Step-by-step explanation:
<em>Add 1.5 to both sides:</em>
5/2x-1.5+1.5=3.5+1.5
5/2x=5
<em>Multiply both sides by 2/5</em>
(2/5)*(5/2x)=(2/5)*(5)
3.14 x 10^-3 = 0.00314...since ur exponent is negative, ur gonna move the decimal 3 spaces to the left...if the exponent would have been positive, u would have moved the decimal 3 spaces to the right.
Answer:
x=1.714285714 or x=1.71
Step-by-step explanation:
Distribute 8 to x and 8 (8x+64)
Get rid of -13x on the other side of the equation by doing +13x to both sides.
That should leave you with 21x+64=100.
Subtract 64 from both sides of the equation.
21x=36
Divide 21 from both sides which will leave you with the answer as a long decimal so round it.
x=1.71
