5a, because both are divided by 5 as the greatest common factor, and a to the first power (not a squared or cubed) is the greatest variable power they share :)
The first thing you do is cross multiply which is 3/4x=48 (3/4 = 0.75). Therfore you divide each side by .75. The left side cancels out. For the right side you divide 48 by .75 and gives you 64. x=64
Answer:
6.2 =x
Step-by-step explanation:
cos 70 =x/18
Multiply each side by 18
18cos 70 =x/18 *18
18cos 70 =x
6.15636258 = x
To the nearest tenth
6.2 =x
Answer: 0.52
