Mrs. carle returned 10 books to the library. when she looked back in her classroom, she now had 88 books. write an algebraic equation to figure out how many books she started with

x - 10 = 88

Step-by-step explanation:

Algebraic equation is simply an equation that includes a variable.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
