Answer:
It should be 42.25 instead
Step-by-step explanation:
Answer:
#30,000
Step-by-step explanation:
Intrest=15,000
Time=10yrs
Percent=5.0%
Rate=?
R=I*100/PT
R=15,000*100/5.0*10
R= 1500000/50
R=30,000
2.1x + 4.2y = 14.7 is the same as x + 2y = 7 (divide both sides by 2.1)
-5.7x-1.9y=-11.4 is the same as 3x + y = 6 (divide both sides by -1.9)
Rearrange the first equation to get x = 7 - 2y and substitute into the second equation, 3(7 - 2y) + y = 6, 21 - 6y + y = 6, 5y = 15, y = 3
Substitute y = 3 into the first equation x + 2(3) = 7, x = 1
x = 1 and y = 3
Basically use pythagorean theorem to solve :))
Square root of 4/25 is 0.08
