2 6 + 3 * 4 2 + 7 * - 2 /
Artist 52 [7]

Answer:

26 + 3 x 42 + 7 x -2 = 138

Step-by-step explanation:

Ok bud, first step we must convert our symbols (Makes it easier to solve)

26 + 3 x 42 + 7 x -2

* subsitutes for multiplication.

I recommend using PEMDAS at times:

1 - Parentheses

2 - Exponents and Roots

3 - Multiplication

4 - Division

5 - Addition

6 - Subtraction

Yet again your numbers were spaced out could they be exponents? if so:

3x^{42}+7x+24

Our answer would round to 24 but he equation was not put in a valid or straight forward way.

Simple interest of $725 at 3.25% for 6 months
Rzqust [24]

The simple interest on the principal amount of $725 at a rate of 3.25% for 6 months is $736.78

<h3>What is simple interest? </h3>

Simple interest is calculated on the loan principal amount or the initial deposit into a savings account. It can be determined by using the formula:

\mathbf{S.I = P(1 + rt)}

where:

  • P = principal = $725
  • R = rate = 3.25%
  • T = time = 6 months = 0.5 years

\mathbf{S.I = 725(1 + 0.0325(0.5))}

S.I = $736.78
