Evaluate a5 − bc + 4a ÷ c when a = 2, b = 3, and c = 8.
please check
To evaluate the expression a^5 - bc + 4a ÷ c when a = 2, b = 3, and c = 8, we substitute these values into the expression:
a^5 - bc + 4a ÷ c
(2)^5 - (3)(8) + 4(2) ÷ 8
Calculating each part of the expression:
(2)^5 = 32
(3)(8) = 24
4(2) = 8
8 ÷ 8 = 1
Now we can substitute these values back into the expression:
32 - 24 + 1
Calculating this expression:
32 - 24 + 1 = 9
Therefore, when a = 2, b = 3, and c = 8, the expression a^5 - bc + 4a ÷ c has a value of 9.
double check im insecure
Sure, let's double-check the calculation.
Given:
a = 2
b = 3
c = 8
Expression:
a^5 - bc + 4a ÷ c
Substituting the values:
(2)^5 - (3)(8) + 4(2) ÷ 8
Evaluating each part of the expression:
(2)^5 = 32
(3)(8) = 24
4(2) = 8
8 ÷ 8 = 1
Substituting the values back into the expression:
32 - 24 + 1
Calculating the expression:
32 - 24 + 1 = 9
Therefore, when a = 2, b = 3, and c = 8, the expression a^5 - bc + 4a ÷ c indeed evaluates to 9.
thank you, what about this?
A truck rental costs $2 per miles, m , driven plus a $24 rental fee. Translate the words into an algebraic expression.(1 point)
The expression is [ ]
.
The algebraic expression for the given scenario is:
2m + 24
This expression represents the cost (in dollars) of renting a truck based on the number of miles driven (m). The term 2m represents the cost for the miles driven at a rate of $2 per mile, and the term 24 represents the fixed rental fee of $24.

the sum of 5 and a number p
the quotient of 5 and a number p
the quotient of 5 and a number p
the product of 5 and a number p
the product of 5 and a number p
the difference of 5 and a number p
The expression "5p" is translated into words as "the product of 5 and a number p."
can you please explain further?
Sure!
The expression "5p" can be broken down into two parts: "5" and "p".
The number "5" represents a constant value.
The variable "p" represents a number that can vary or change.
The term "5p" is formed by multiplying the constant value of 5 by the variable p.
So, "5p" can be translated into words as "the product of 5 and a number p."
