The value of r is -21/9.
The term BODMAS, which stands for brackets of, division, multiplication, addition, and subtraction, might be used to simplify the expression. It specifies how to answer a mathematical expression in a particular order.
-13=r/9+8
-13-8=r/9
-21=r/9
-21/9=r
What is Expressions and Equations?
Algebraic expressions include variables, numbers, and operational signs. Examples include multiplication, division, exponentiation with the natural exponent, addition, and subtraction.
Fractional expression is the name given to division in an algebraic expression with variables.
Rational numbers are those that can be expressed in fractional form.
An algebraic expression is referred to as being irrational if it contains the variable's root or a fractional power with a changeable base.

Answer:
Step-by-step explanation:
<em>Hope this helps!!!</em>
Answer:
Constants: The terms which are free from variables.
Numerical coefficient: Number multiplied with a variable.
(i) Constant = -3
Term which is not constant = 5x
Numerical coefficient = 5
(ii) 5x-3
Constant = 11
Term which is not constant
Numerical coefficient = -2
(iii) 11-2y squared
Constant = -1
Term which is not constant = 2x
Numerical coefficient = 2
Therefore, the terms which are not constants are 5x,-2y squared,2x respectively and their numerical coefficients are 5, -2, 2 respectively.

First, add '5' to both of the sides.
Second, add '3 + 5' to get 8.
Third, multiply both sides by '4' to get rid of the fraction.
Fourth, multiply '8 × 4' to get '32'.
Fifth, you can switch your sides.
Answer:
Answer:45
Step-by-step explanation:
Any number raised to the 0 power equals 1. So, 5 x 10^0 is the the same as (5x1)x(9x1)
5x1=5 9x1=9 5x9=45
