Answer:
1) 180 degrees; straight angle
2) (5x-18)+(4x+45)=108
3) x=17
4) 90 degrees; right angle
5) (3x+6)+(5x+4)=90
6)x=10
Step-by-step explanation:
<span>601.2 rupees
You've been given the equation:
r = 62.4d - 210
I will assume that 62.4 is the actual exchange rate and that the 210 is a service fee of some sort for performing the exchange. So with 13 dollars, let's substitute that value into the equation and calculate:
r = 62.4d - 210
r = 62.4*13 - 210
r = 811.2 - 210
r = 601.2
So you'll get 601.2 rupees.</span>
Answer:
150x + 280y = 1310
Step-by-step explanation:
Since we are working with an equation written in scientific notation and we are dealing with a negative exponent, we are going to divide 4.7 by 10 three times.
4.7 / 10 = 0.47
0.47 / 10 = 0.047
0.047 / 10 = 0.0047
Best of Luck!
