Answer:

8.2

So if c=4, the equation will be (4 × 4) - 7.8. Use PEMDAS (parenthesis, exponents, multiplication, division, addition, & subtraction) to solve.

4 × 4 = 16

16 - 7.8 = 8.2

<h2>Answer:</h2>

4(c) - 7.8 when c = 4 equals 8.2.

I hope this helps :)

Can anyone please help I’ve been working on this one for awhile
Karo-lina-s [1.5K]
The diagram shows that angle AQB = angle BQC
So 5x= 8x-24
3x= 24
x=8 (first answer)


AQB= 5(8) = 40 (second answer)


BQC= 8(8)-24 = 64-24 = 40 ( third answer)



AQC = AQB+ BQC
AQC= 40+40 = 80 (Fourth answer)


(Mark me the brainliest if this has helped)
