Answer:
x = 18.5
Step-by-step explanation:
sin0 = opp/adj
tan51 = x/15
tan51 • 15 = x
18.5 = x
250+25x=150+50x
Subtract 150 from both sides
100+25x=50x
Subtract 25 from both sides
100=25x
Divide both sides by 25
X=4

Answer: 0.95 x 10^2
Explanation:
2.85 x 10^6/30,000
= 2.85 x 10^6/3 x 10^4
= 2.85 x 10^2/3
= 0.95 x 10^2
Answer:
7/10, 6/10, or 5/10
Step-by-step explanation:
So, first, we change 4/5 into tenths. That equals 8/10. 3/10 and 8/10.
10x - 18y = 84 6=x substitute 6 for x so its 6 * 10
60 - 18y = 84 subtract 60 from both sides
-18y = 24 divide by -18
y = -1 1/3
check!
60 + 24 = 84
84 = 84
