Shown below are the steps a student took to solve the simple interest formula A = P(1 + rt) for r. uppercase A = uppercase P (1 + r t). uppercase A = uppercase P + r t. uppercase A minus uppercase P = r t. r = StartFraction (uppercase A minus uppercase P) Over t End Fraction

Explain the algebraic error in the student’s work. Then, state how the equation r = StartFraction (uppercase A minus uppercase P) Over t EndFraction can be modified to produce the correct result.


The student did not distribute properly to get A=P+Prt
The equation can be fixed by putting a factor of P in the denominator: r= (A-P)/(Pt)

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
