9/10 cannot be a mixed number. It is the final fraction.
Answer:
C angle H = 75.4
Step-by-step explanation:
In order to find the measure of angle H we must first find the value of x
Firstly it's good to know that the sum of the angles in a quadrilateral always add up to 360 degrees
Knowing this we can create an equation.
Since the angle measures must add up to 360 degrees we know that angle F + angle E + angle H + angle G = 360
Plugging in the given expressions for each angle we acquire
14x - 11 + 5x + 21 + 6x + 16 + 8x - 7
We can now solve for x
==> combine like terms
33x + 19 = 360
==> subtract 19 from both sides
33x = 341
==> divide both sides by 33
x = 10 1/3
Now that we have identified the value of x and we can plug in x = 10 1/3 into the given expression of angle H and evaluate to get the measure
Angle H = 8x - 7
==> plug in x = 10 1/3
Angle H = 8(10 1/3) - 7
==> multiply 8 and 10 1/3
Angle H = 82.7 - 7
==> subtract 7 from 82.7
Angle H = 75.6
C is the closest answer
2x - 3y = 3.....multiply by 4
5x - 4y = 4....multiply by -3
--------------
8x - 12y = 12 (result of multiplying by 4)
-15x + 12y = -12 (result of multiplying by -3)
-------------
- 7x = 0
x = 0 <===

Answer:
Step-by-step explanation:
First we must find the missing number, for that we apply a simple rule of three:
3. 4
27 ------ x
x = 27 (4) / 3 = 36
Now we just do the sum:
27 + 36 = 63
