Answer:
x = 0
Step-by-step explanation:
Solve for x:
x/5 + 5 = 5
Put each term in x/5 + 5 over the common denominator 5: x/5 + 5 = x/5 + 25/5:
x/5 + 25/5 = 5
x/5 + 25/5 = (x + 25)/5:
(x + 25)/5 = 5
Multiply both sides of (x + 25)/5 = 5 by 5:
(5 (x + 25))/5 = 5×5
(5 (x + 25))/5 = 5/5×(x + 25) = x + 25:
x + 25 = 5×5
5×5 = 25:
x + 25 = 25
Subtract 25 from both sides:
x + (25 - 25) = 25 - 25
25 - 25 = 0:
x = 25 - 25
25 - 25 = 0:
Answer: x = 0
The three inside angles of a triangle equal 180 degrees,
If one angle is 110, subtract that from 180 to find the total of the other two.
180 - 110 = 70
The other two angles equal 70 degrees.
5 - 4 + 7x + 1 = 7x + (5 - 4 + 1) = 7x + 2
NO SOLUTIONS:
<em>5 - 4 + 7x + 1 = 7x + a </em><em>(a - any real number, except 2)</em>
ONE SOLUTION:
<em>5 - 4 + 7x + 1 = bx + c </em><em>(b - any real number, except 7, c - any real number)</em>
INFINITELY MANY SOLUTIONS:
<em>5 - 4 + 7x + 1 = 7x + 2</em>
Examples:
2x + 3 = 2x + 5 <em>subtract 2x from both sides</em>
3 = 5 FALSE <em>(NO SOLUTIONS)</em>
2x + 3 = x - 4 <em>subtract x from both sides</em>
x + 3 = -4 <em>subtract 3 from both sides</em>
x = -7 (<em>ONE SOLUTION)</em>
2x + 3 = 2x + 3 <em>subtract 2x from both sides</em>
3 = 3 TRUE <em>(INFINITELY MANY SOLUTIONS)</em>
8z means 8 times z
z=8
8(8)+3

We can assign the value "2x" as the amount of money that Amelia which to achieve in twelve years.
So, his initial money is X.
We can try each percent to test if it could double the amount in 12 years.
x+0.06*12years*x=1.72X
x+0.12*12*x=1.44x
x+0.1*12*x=2.2x
x+0.166*12*x=2.992x
Therefore, the answer is 10 percent.
