Answer:
x = -6
Step-by-step explanation:
y = -x equation 1
x + 6y = 30 equation 2
using equation 1 in equation 2 we have:
x + 6(-x) = 30
x - 6x =30
-5x = 30
x= -30/5
x= -6
The fraction 30/80 is equivalent to 37.5 percent or 37.5% (rounded to 1 decimal place).
To workout this, divide the numerator by the denominator, sum this value to the integer part then multiply the result by 100%, so:
30/80 in percent = 30 ÷ 80 × 100% =
0.375 × 100% =
37.5%
575* 0.05 = 28.75
28.75* 2.5(yrs) = 71.875
575+ 71.875 = 646.875
therefore, $646.87
