6x-1=4x+6
subtracting 4x from each side
2x-1=6
adding 1 to each side
2x=7
divide by 2
x=7/2 or 3.5
check: 6(7/2) -1 =4(7/2)+6
21-1 =14+6
20=20 correct
Step-by-step explanation:
12. Cos 60° = 8/c
0,5 = 8/c
0,5 c = 8
c = 16
D² = V16²-8²
= V256-64
=V192 = V16×12 = 4V12
= 4V4×3 = 8V3
13. Cos 30° = 6/b
V3/2 = 6/b
V3 b = 12
b = 12/V3
b/Sin B = a /sin A
b/Sin90° = 6/ sin 60°
<u>b</u> = <u> </u><u> </u><u> </u><u>6</u><u> </u><u> </u><u> </u>
1 V3/2
b× <u>V3</u> = 6
2
b = 6× 2/V3
= 12/V3
Answer:
j=5.25
Step-by-step explanation:
j+22/8=8
j=8/1-22/8
j=64-22/8
j=5.25
Proof:
5.25+22/8=8
525/100+22/8=8
4200+2200/800=8
6400/800=8
8=8
Answer:
ab
Step-by-step explanation:
Answer:
50 mg for (dex) and 500 (gua) 50 times 4 is 200 for dex for ml mg is something else though. Also 500 times 4 is 2000 ml. So now just convert.
