7 tenths, 7/10. or 70 percent.
Answer:
x=-1
Step-by-step explanation:
<em>Add by 1 from both sides of equation.</em>
<em>9x-1+1=-11+1</em>
<em>Simplify.</em>
<em>-11+1=-10</em>
<em>9x=-10</em>
<em>Divide by 9 from both sides of equation.</em>
<em>9x/9=-10/9</em>
<em>Simplify, to find the answer.</em>
<em>x=-10/9</em>
<em>x=-1 is the correct answer.</em>

Answer:
The answer is <ACD = 68°
Step-by-step explanation:
Using the property that the sum of interior angles in a triangle is equal 180°,we have:
<DAC + <ACD + <ADC = 180°

Finally, calculating the angle <ACD, we have:
<ACD = 180 - 4x
<ACD = 180 - 4 . 28
<ACD = 180 - 112
ACD = 68°
7/8. 8×5=40. 35/40
9/10. 10×4=40. 36/40
