No.

Step-by-step explanation:

Substitue x = -5 in the equation 5x - 12 = -5(-x + 13)

You'll eventually get -37=-90

No I don't think so..

Answer:

-53

Step-by-step explanation:

<u><em>Distribute</em></u>

5 − 1 2 = − 5 ( − +1 3 )

5 − 1 2 = 5 − 6 5

<em><u>Add  1 2  to both sides of the equation  </u></em>

5x-12=5x-65

5x−12+12=5x−65+12

<em><u>Simplify</u></em>

<em><u> </u></em>5x=5x-53

<u><em>Subtract   5x  from both sides of the equation</em></u>

5x=5x-53

5x-5x=5x-53-5x

<em><u>Simplify</u></em>

-53

Syke Under Shield
Lana71 [14]

Answer:

For Skye - 15.85%

For under shield - 5%

Skye is using its asset more efficiently because its ROA is higher

Step-by-step explanation:

Return on total assets =  Net income / Average total assets

For Skye

$3192 /  [(18,764 + 21,512)/2] = 0.1585 = 15.85%

For under shield

$ 649 / [(10,252 + 15,659)/ 2] = 0.05 = 5%

Skye is using its asset more efficiently because its ROA is higher

A = √7 + √c and b = √63 + √d where c and d are positive integers.
mrs_skeptik [129]

Answer:

\displaystyle a:b=\frac{1}{3}

Step-by-step explanation:

<u>Ratios </u>

We are given the following relations:

a=\sqrt{7}+\sqrt{c}\qquad \qquad[1]

b=\sqrt{63}+\sqrt{d}\qquad \qquad[2]

\displaystyle \frac{c}{d}=\frac{1}{9} \qquad \qquad [3]

From [3]:

9c=d

Replacing into [2]:

b=\sqrt{63}+\sqrt{9c}

We can express 63=9*7:

b=\sqrt{9*7}+\sqrt{9c}

Taking the square root of 9:

b=3\sqrt{7}+3\sqrt{c}

Factoring:

b=3(\sqrt{7}+\sqrt{c})

Find the ration a:b:

\displaystyle a:b=\frac{\sqrt{7}+\sqrt{c}}{3(\sqrt{7}+\sqrt{c})}

Simplifying:

\boxed{a:b=\frac{1}{3}}

What is the solution to the given inequality?
SashulF [63]

1/2 - 1/4x ≥ -1/4

Combine 1/4x to get x/4:

1/2 - x/4 ≥ -1/4

Subtract 1/2 from both sides:

-x/4 ≥ -1/4 - 1/2

Simplify:

-x/4 ≥ -3/4

Multiply both sides by 4:

-x ≥ -3/4 * 4

-x ≥ -3

Multiply each side by -1 ( and since you are multiplying by -1, you also need to reverse the inequality sign)

Answer: x ≤ 3
