Answer:
14/17
Step-by-step explanation:
Find the value to make the equation true
1) ?/1 = 14/17
x : 1 = 14 : 17
x = 1 * 14 : 17
x = 14 : 17
x = 14/17
Let's take an example to illustrate this case:
<span>positive fraction = 2/7
</span>
<span>negative fraction = - 3/5
Now we need to subtract </span><span>- 3/5 from 2/7
Right?
2/7 - (-3/5) = 2/7 + 3/5
here we need to unify the denominators as follows:
the lowest common factor between 7 and 5 is 35
2/7 = 10/35
3/5 = 21/35
Now back to </span><span>2/7 + 3/5:
</span><span><span>2/7 + 3/5 = 10/35 + 21/35 = (10+21)/35 = 31/35
That's it
Hope that helps you</span>

Answer:
angle D = 54°
Step-by-step explanation:
Supplementary angles sum to 180°
To calculate D, subtract angle C from 180
angle D = 180° - 126° = 54°
