-7c+9=c+1 (subtract c on both sides)
-8c+9=1 (subtract 9 on both sides)
-8c=-8 (divide by -8 on both sides to get c by its self)
c=1
your answer is 1.
HI
the answer is 200 millimeters
<333
Isn't it 5? x=5 cause the model's height is 4 less than the width so like if the actual width is 9 than the height is 4 smaller
27.8 × 9.6 is equal to <span>266.88</span><span>
So, the closest would be A. 280.</span>
Total: 318
Student tickets: x
Adult tickets: 3x+6
x+(3x+6)=318 -> 4x+6=318 -> 4x=312 -> x=78
3(78)+6 = 234+6 = 240
240 adult tickets were sold
