L -2= (1/5)w

P = 2l +2w

P = 2((w/5)+2) +2w

P = 2((10+w)/5 +2w

Y/x^2 + y/x^3<br><br>perform the operation and express your answer as a single fraction

umka2103 [35]

Answer:

$\frac{y}{x^2}+\frac{y}{x^3}=\frac{yx+y}{x^3}$

Step-by-step explanation:

Given the expression

$\frac{y}{x^2}+\frac{y}{x^3}$

Let us perform the operation and express your answer as a single fraction

$\frac{y}{x^2}+\frac{y}{x^3}=\frac{x^3y+x^2y}{x^5}$

$=\:\frac{x^2\left(xy+y\right)}{x^5}$

$=\frac{\left(xy+y\right)}{x^3}$

Therefore, we conclude that:

$\frac{y}{x^2}+\frac{y}{x^3}=\frac{yx+y}{x^3}$

Water freezes at 0° Celsius. The table shows five different temperatures in degrees Celsius. Indicate whether each temperature i

KATRIN_1 [288]

0.5 is above because that .5 of a change is keeping the water from freezing because it is still slightly babouche freezing point.

-13 is below because the number is a negative so is below 0 anyway and is below the freezing point.

100 is above because the number 100 is higher than 0 so it’s above freezing point.

5.5 is above because it is a larger number than the freezing point so the water would not freeze yet at this temperature.

-2.25 is below because it’s a negative number.

I think that’s what you meant not 100% sure but that’s how I would do it :)

When solving systems of equations with the elimination

viktelen [127]

Step-by step explanation:

That's a great question. Look for things such as these:

x=x (infinite solution)

x=12 (one solution)

x+3 = x + 5 (no solutions)

M(5, 7) is the mid-point of the l.ine segment joining A (3,4) to B. Find the coordinates of B.

Nina [5.8K]

Answer:

B(7,10)

Step-by-step explanation:

$M(5,7)=(x ,y)\\A(3,4)=(x_1,y_1)\\B(x_2,y_2)\\\\Endpoint ;\\x = \frac{x_1+x_2}{2}\\ \\5 = \frac{3+x_2}{2}\\ Cross\:Multiply\\5\times 2 =3+x_2\\10=3+x_2\\10-3 =x_2\\7=x_2\\\\\\y = \frac{y_1+y_2}{2} \\\\7 = \frac{4+y_2}{2}\\ Cross\:Multiply\\7\times 2 =4+y_2\\14 =4+y_2\\14-4 =y_2\\10 =y_2\\\\\\B(7,10)$

Solve the inequality <br> 21≥t+10

olchik [2.2K]

The answer is t ≤ 11.

Subtract 10 from each side.

21 - 10 ≥ t + 10 - 10
t ≤ 11
