Answer: 54-x

Explanation:

1. We define the variable which is x or n (whichever you choose)

2. We write the algebraic expression that models the following problem:

the difference of 54 and a number.

3. We end up with our answer: 54-n OR 54-x

(Variable doesn't matter but most people use x when they don't have a named variable)

Hope this helps!!

Solve tor r.<br> *a(5 – x) = bz - 8

Mars2501 [29]

Answer:

See explanation

Step-by-step explanation:

Assuming the given equation is

$a(5 - r) = bz - 8$

To solve for r, we first divide both sides by a.

$5 - r = \frac{ bz - 8}{a}$

We now subtract 5 from both sides:

$- r = \frac{ bz - 8}{a} - 5$

We now divide through by - 1 to get:

$r = 5 - \frac{ bz - 8}{a}$

$r = \frac{5a - bz + 8}{a} \: \: where \: a \ne0$

$3x^2 + 2x + 2 =0\\\\\Delta=2^2-4\cdot3\cdot2=4-24=-20$

No solutions in real numbers. So <u>D.</u>

Need answer to this problem

Lana71 [14]

Distribute the exponent in the numerator:

$\dfrac{(10w^3)^2}{5w}=\dfrac{10^2w^6}{5w}$

Then if $w\neq0$ , we can cancel one of each $w$ in the numerator and denominator:

$\dfrac{10^2w^6}{5w}=\dfrac{10^2w^5}5$

Finally, the square of 10 is 100, and 100 divided by 5 is 20, so we're left with (C),

$20w^5$
