Answer:
x=9, y=10. (9, 10). The two numbers are 9 and 10.
Step-by-step explanation:
3x+5y=77
x+y=19
------------------
3x+5y=77
-3(x+y)=-3(19)
---------------------
3x+5y=77
-3x-3y=-57
-------------------
2y=20
y=20/2
y=10
x+10=19
x=19-10
x=9
21,935,483.87 rounded to the nearest million is 22,000,000.00
I = PRT
14,300 = (700)(0.0725)(t)
14,300 = 50.75(t)
14300/50.75 = t
281.77 = t or t = 281.77
hope this helps :)
4y is 55% of 7.27 i believe?
(21 * 1.10) / 3 = 23.10/3 = 7.7....so each friend has to pay $ 7.70
