The amount of money invested at 12% was $4327 while $1442 was invested at 7%.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount invested at 12% and y represent the amount invested at 7%, hence:
x + y = 5679 (1)
Also:
0.12x = 0.07y + 407.5 (2)
From both equations:
x = 4327, y = 1442
The amount of money invested at 12% was $4327 while $1442 was invested at 7%.

factor out the x+1 from the numerator and denominator to get
denominator: x³ - x = x(x² - 1) x(x-1)(x+1)
Answer: J
That week: $500
Commission 5,000*0,04=200 (4%=4/100=0,04)
salary 300
300+200=500
Sum of all the angles is equal to 180.
so, 39 + 102 + x = 180
x + 141 = 180
x = 180 - 141
x = 39
In short, Your Answer would be 39
