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.

Which of the following is a correct interpretation of the expression -4 + 13−4+13minus, 4, plus, 13?

MaRussiya [10]

the sum between negative 4 and 13, this can be tought as:

Stepping on -4 and moving 13 units to the right.
Stepping on 13 and moving 4 units to the left.

<h3>Which is the interpretation of the given expression?</h3>

The expression is just the sum:

-4 + 13

So we have the sum between negative 4 and 13, this can be tought as:

Stepping on -4 and moving 13 units to the right.
Stepping on 13 and moving 4 units to the left.

Now, none of the written options (a, b, and c) depict any of this, so I assume that the correct option is the one that you did not write, which is option D.

Help needed!!! Please

Sliva [168]

Answer:

<em>The correct option is: C. $x=6\sqrt{3}, y=12$ </em>

Step-by-step explanation:

The two angles of the triangle are given as 60° and 60°

As the sum of all three angle in any triangle is always 180°, so the measure of the third angle will be: 180°-(60°+60°) = 180° - 120° = 60°

Now each angle of the triangle is 60°, it means the triangle is equilateral.

The base of the triangle is given as 12. So, the length of each side will be 12.

That means, the value of $y=12$

Now in the left right triangle.....

$Sin(60)=\frac{x}{y} \\ \\ \frac{\sqrt{3}} {2}=\frac{x}{12} \\ \\ 2x=12\sqrt{3} \\ \\ x=6\sqrt{3}$

So, the value of $x = 6\sqrt{3}$

A builder needs to cover 10 square yards of floor with tile. red tile costs $60 per square yard, and white tole costs $40 per sq

dsp73

Answer:40 square yards

Step-by-step explanation:

Given

Floor area A=10 square yards

Red tile costs $\$ 60$ per square yards

White tile costs $\$40$ per square yards

Total money spent= $\$480$ on tiles

Suppose red tiles cover an area of $x$ square yards

So, we can write

$60\times x+40\times (10-x)=480\\60x+400-40x=480\\20x=80\\x=40\ \text{square yards}$

Red tiles cover an area of 40 square yards
