The answer you are looking for is C.) 1 1/4.

To find this answer, you need to make 1 3/4 into an improper fraction. This can be done by multiplying the whole number (1) by the denominator (4) and adding it to the numerator (3). So, 1 * 4 = 4 and 3 + 4 = 7. Now your problem says 12/4 - 7/4. Finally, subtract the fractions, keeping in mind the denominators stay the same, but you subtract the numerators. 12/4 - 7/4 = 5/4. 5/4 converted to a mixed fraction is 1 1/4. Thus making 1 1/4 the answer.

I hope this helps!

Philip

*seed attachment for diagram

Answer:

83°

Step-by-step explanation:

Given:

Philip = (8x + 12)°

Matt = (55 - 3x)°

George = (10x + 23)°

Required:

Measure of angle at George's position

SOLUTION:

Find the value of x

(8x + 12)° + (55 - 3x)° + (10x + 23)° = 180° (sum of the interior angles of a ∆)

8x + 12 + 55 - 3x + 10x + 23 = 180

Add like terms

15x + 90 = 180

15x = 180 - 90 (subtraction property of equality)

15x = 90

x = 90/15 (division property of equality)

x = 6

✔️George = (10x + 23)°

Plug in the value of x

George = 10(6) + 23 = 60 + 23

= 83°
