Answer:

x = 8

DE = 52

Step-by-step explanation:

MD = ME

4x-6 = 3x +2

solve for x;

4x-3x = 2+6

x = 8

Now solve for MD and ME by substituting the x = 8 to each equation

MD = 4(8) - 6 = 32 - 6 = 26

ME = 3(8) + 2 = 24 +2 = 26

Since M is the midpoint, its in the middle of DE, so the length of DE is obtained by adding the length of MD + ME;

DE = 26 + 26

DE = 52

6-7(x+1)= -3(2-x)<br> How do you solve this?

kicyunya [14]

<h3><u>Explanation</u></h3>

Given the equation.

$6 - 7(x + 1) = - 3(2 - x)$

Distribute/Simplify

$6 - 7x - 7 = - 6 + 3x \\ - 1 - 7x = - 6 + 3x$

Solve the equation for x-term by making x as the subject.

$- 1 + 6 = 7x + 3x \\ 5 = 10x \\ \frac{5}{10} = x \\ \frac{1}{2} = x$

Answer Check by substituting the value of x in the equation.

$6 - 7( \frac{1}{2} ) - 7 = - 6 + 3( \frac{1}{2} ) \\ 6 - \frac{7}{2} - 7 = - 6 + \frac{3}{2} \Longrightarrow \sf{You \: \: can \: \: change \: \: sides \: \: to \: \: make \: \: it \: \: easier} \\ 6 - 7 + 6 = \frac{7}{2} + \frac{3}{2} \\ 5 = \frac{10}{2} \\ 5 = 5 \: \green{ \checkmark}$

The equation is true for x = 1/2.

<h3><u>Answer</u></h3>

<u> $\large \boxed{x = \frac{1}{2} } \: \: \: \: \green{ \checkmark}$ </u>

No wonder you have posted this. It is not easy. Scale is a straight line measurement. You need to use a side of a square.

Left: 1 side of a square = 1 meter.

Center: 3 tops of a square = 1 meter.
Therefore 1 side of a square = 1/3 of a meter.

Right: 1 side of a square = 0.5 meters.

I need help whats 5/8 + 14 the 5/8 is a fraction

Katarina [22]

Hey there!

5/8 + 14 = ?

We can say 14 is equal to 14/1 beause it doesn't have a denominator and we will need to solve for your equation

14 * 8 = 112 (upcoming numerator for now)

8 * 1 = 8 (upcoming denominator for now)

5 stays alone

New equation 5 + 112 / 8

5 + 112 = 117 (numerator)

8 = 8 (demominator)

Answer: 117/8 (if you're looking for the improper fraction version) ; 14 5/8 (if you're looking for the mixed number version) ; 14.625 (if you're looking for the decimal version of it)

⬆ ANY one of these choices SHOULD work

Good luck on your assignment and enjoy your day!
