Answer:
x = 1/7
Step-by-step explanation:
23x - 15x = x-1
8x = x - 1
8x - x = 1
7x = 1
x = 1/7
3 consecutive even integers : x, x + 2, x + 4
x + (x + 2) + (x + 4) = -84.....combine like terms
3x + 6 = - 84.......subtract 6 from each side
3x = -84 - 6
3x = - 90...divide both sides by 3
x = -90/3
x = -30
x + 2 = -30 + 2 = -28
x + 4 = -30 + 4 = -26
so ur 3 numbers are : -26, -28, -30
this picture will explain you
the answer is 10
The answer would be 4/85
1. 2/5 ÷ 8 * 2 + 1 over 2
2. 2/5 ÷ 16 + 1 over 2
3. 2/5 ÷ 17/2
4. 2/5 * 2/17
5. 2 * 2 over 5 * 17
6. 4 over 5 * 17
7. finally 4/85
If a root is a+√b then another is a-√b because of quadatic formula
r2=1-√5
