Answer:

Expression for the total cost is $1J.

Step-by-step explanation:

Given that each granola bar costs $1.

Now we need to write an expression that shows the total costs of the granola bars using the variable J.

So let's assume that the number of granola bars = J

then total cost of g granola bars = (J)($1) = $1J

Hence required expression for the total cost is 1J dollars.

18pi rounded to the nearest whole number

Bingel [31]

Answer:

56.52 but you have to round so its 57

Step-by-step explanation:

You have to multiply 18 and pi so we will use 3.14 for pi. 18 times 3.14 will give you 56.52 but you have to round it so it will be 57. If the number is greater than 5 you round up but if it is less you round down.

What is the difference? StartFraction 2 x 5 Over x squared minus 3 x EndFraction minus StartFraction 3 x 5 Over x cubed minus 9

The expression which is equivalent to the difference of the given algebraic fraction is,

$\dfr\dfrac{(x+5)(x+2)}{x(x-3)(x+3)}$

<h3>What is the difference? </h3>

Difference is the mathematical operation in which the one number is subtract from another number.

To find the difference of two fraction numbers, we find the least common factor of denominator and write the all numbers as one fraction.

The given expression in the problem is,

$\dfrac{2x+5}{x^2-3x}-\dfrac{3x+5}{x^3-9x}-\dfrac{x+1}{x^2-9}$

Factorize the denominator of each term as,

$\dfrac{2x+5}{x(x-3)}-\dfrac{3x+5}{x(x-3)(x+3)}-\dfrac{x+1}{(x-3)(x+3)}$

Here, the least common factor of the denominators is x(x-3)(x+3), therefore, the expression can be written as,

$\dfrac{(x+3)(2x+5)-(3x+5)-(x)(x+1)}{x(x-3)(x+3)}\\\dfr\dfrac{2x^2+5x+6x+15-3x-5-x^2-x}{x(x-3)(x+3)}\\\dfr\dfrac{x^2+7x+10}{x(x-3)(x+3)}\\\dfr\dfrac{(x+5)(x+2)}{x(x-3)(x+3)}$

Hence, the expression which is equivalent to the difference of the given algebraic fraction is,

$\dfr\dfrac{(x+5)(x+2)}{x(x-3)(x+3)}$
