<span>6( 5-8x) +12= -54
30-48x+12=-54 this comes from distributing(multiplying) 6x5 and 6 times -8x
30+12-48x=-54 you have to add the coefficients 30+12
42-48x=-54
-42 -42
-----------------------
-48x=-96 divide by -48
x=2</span>
Answer:
x ≈ 7.4
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos22° = 
= 
Multiply both sides by 8
8 × cos22° = x, thus
x ≈ 7.4 ( to the nearest tenth )
12) 12, 8
12 - 8 = 4
12 + 8 = 20
Answer: 4 < x <span>< 20
13) 11, 3
11 - 3 = 8
11 + 3 = 14
Answer: 8 </span>< x <span>< 14
