We need to start from the innermost parenthesis and work our way out.
The first parenthesis is
. These are not like terms because one involves a variable, while the other is a constant term. Two terms are summable if they involve the same power(s) of the same variable(s).
So, we can take one step outwards, and we arrive to the square brackets. We have

and 2z and -13z are like terms, so we can sum them:

Finally we arrive to the whole expression, which is

Because, again, 5z and 11z were like terms.
The value of expression is 63 when e = 4 and g = 6
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

We have to solve the expression
Given that e = 4 and g = 6
<em><u>Substitute e = 4 and g = 6 in given expression</u></em>

Thus value of expression is 63
$103.92
Process:
64.95/5 = 12.99, 12.99 x 8 = 103.92
Answer:
Algebraic expression representing number of coffee B = 100-x
Step-by-step explanation:
An algebraic expression is an expression that contains unknowns denoted with alphabets or symbols and natural numbers.
Coffee blend is 100 pounds and x represent number of pounds of coffee A
Hence coffee B = 100-x
Algebraic expression representing number of coffee B = 100-x
Answer: (2a+2b,2c)
the first one
Step-by-step explanation:
you can add or subtract letter such as *a or *b so you "add" them which is 2a+2b and "y" for point B is 2c so it stays the same
sorry i such at explaining
