Answer:
12-5=7
12-7=5
Step-by-step explanation:
8n - 7
because from 8n, 7 is subtracted
<span>Angles on one side of a straight line always add to 180°.
Look at the picture.
a = 180° - 134° = 46°
b = 180° - 130° = 50°
</span><span>In a triangle, the three interior angles always add to 180°.
a + b + c = 180°
c = 180° - (46° + 50°) = 180° - 96° = 84°
x° = 180° - 84° = 96°</span>
<span>We can see that:
x = a + b</span>
Answer:
9
Step-by-step explanation:
2(x-11) + 5-1
We can use the distributive property:
2x - 22 + 5 - 1
We can then simplify:
2x - 18
In this case, if 2x - 18 = 0, then 2x = 18 and x = 9.
