Answer:
none is a solution...the solution.is -3
The exchange rate is 60:50 (us:euro)
if you have 70 euros, then x:70
60(x) : 70(50)
60x /60 : 3500/60
x = 58.33
seventy euro dollars = $ 58.33 on that particular day
hope this helps
Answer:n=-3.1
Step-by-step explanation:
2n + 3 = -3.2
Subtract 3 on both sides
2n+3-3=-3.2-3
2n=-6.2
Divide 2 on both sides
2n/2=-6.2/2
n=-3.1
Answer: 4
Step-by-step explanation: Using Sine, Cosine, and Tangent, you use 8 as the hypotenuse and put your 60 w/ you Cos, so it will read cos60*=adj/8. Then you'll multiply both sides by 8, so it will be 8*cos60=adj. So, the cosine of 60 is 1/2, you multiply that by 8, then that equals 4, I hope that helps!
