Answer:

x = 8

Step-by-step explanation:

(please verify) if line segment LM is congruent to line segment PN; then

9x - 25 = 5x + 7; subtract 5x from both sides

4x - 25 = 7; add 25 to both sides

4x = 32; divide by 4

x = 8

Mathematical Statement Justification

olya-2409 [2.1K]

Answer:

Step-by-step explanation:

1. Given mathematical statement

$4x+3=x+5-2x$

So,

$\begin{array}{cc}4x+3=x+5-2x&\text{ Given}\end{array}$

2. Rewrite it as

$4x+3=x-2x+5$

So,

$\begin{array}{cc}4x+3=x-2x+5&\text{ Commutative property of addition}\end{array}$

3. Combine like terms $x$ and $-2x:$

$4x+3=-x+5$

So,

$\begin{array}{cc}4x+3=-x+5&\text{ Combine like terms}\end{array}$

4. Add $x$ to both sides:

$4x+3+x=-x+5+x\\ \\5x+3=5$

So,

$\begin{array}{cc}5x+3=5&\text{ Addition property of equality}\end{array}$

5. Subtract 3 from both sides:

$5x+3-3=5-3\\ \\5x=2$

So,

$\begin{array}{cc}5x=2&\text{ Subtraction property of equality}\end{array}$

6. Divide both sides by 5:

$x=\dfrac{2}{5}$

So,

$\begin{array}{cc}x=\dfrac{2}{5}&\text{ Division property of equality}\end{array}$

Find the area of the following ellipse. a = 4.5 m; b = 5.5 m

LenaWriter [7]

Answer:

Area of ellipse is ≈ 77.78 $m^{2}$

Step-by-step explanation:

Given the dimension of ellipse

a = 4.5 m

b = 5.5 m

Now, Area of ellipse = $\pi ab$

= $\frac{22}{7}\times 4.5\times 5.5$

= $\frac{5445}{70}$

= 77.78 $m^{2}$

Hence Area of ellipse will be 77.78 $m^{2}$
