Answer:

-3

Step-by-step explanation:

According to the question,

$\longrightarrow$ CE = CD + DE

$\longrightarrow$ 8 = (x + 10) + (x + 4)

$\longrightarrow$ 8 = x + 10 + x + 4

$\longrightarrow$ 8 = 2x + 14

$\longrightarrow$ 8 ― 14 = 2x

$\longrightarrow$ ―6 = 2x

$\longrightarrow$ ―6 ÷ 2 = x

$\longrightarrow$ –3 = x

Therefore, the value of x is ― 3.

Solve -1 < x + 1 ≤ 6

andrey2020 [161]

Answer:

-2<x≤5

Step-by-step :

-1<x+1≤6 So fisrt what every we do to one side we must do to the other. In this case it's a bit different since we are dealing with inequalities.

-1<x+1≤6 I would start off by isolating x in the middle.

-1<x+1≤6 I subtracted 1 from all three sides.

-1 -1 -1

Now your equation should look like this:

-2<x≤5 Now there is really nothing much we can do here since we were just trying to get x by its self.

Answer : -2<x≤5

Karl is building a rectangular garden bed. The length is 6 feet. She has 20 feet of boards to make the sides. Write and solve an

natali 33 [55]

Answer:

The width of the garden bed must be less than or equal to 4 feet.

$w\leq4$

Explanation:

Given that;

She has 20 feet of boards to make the sides.

The perimeter of the garden bed must not be more than 20 feet

$\begin{gathered} P=2l+2w\leq20 \\ 2l+2w\leq20 \end{gathered}$

Given;

The length is 6 feet;

$l=6$

To get the inequality for the width w, let us substitute the value of the length into the inequality above and simplify;

$\begin{gathered} 2l+2w\leq20 \\ 2(6)+2w\leq20 \\ 12+2w\leq20 \\ 2w\leq20-12 \\ 2w\leq8 \\ \frac{2w}{2}\leq\frac{8}{2} \\ w\leq4 \end{gathered}$

Therefore, the width of the garden bed must be less than or equal to 4 feet.

$w\leq4$
