X + (x + 10) = 154
2 x + 10 = 154
2 x = 154-10 = 144
x = 72 (ans)
Not sure if it’s right

3p - 2(p-4) = 7p + 6

Serggg [28]

For this case we must find the value of the variable "p" of the following equation:

$3p-2 (p-4) = 7p + 6$

We apply distributive property on the left side of the equation taking into account that $+*-=-$ and $- * - = +$ :

$3p-2p + 8 = 7p + 6$

We add similar terms:

$p + 8 = 7p + 6$

We subtract $7p$ from both sides of the equation:

$p-7p + 8 = 6\\-6p + 8 = 6$

We subtract 8 from both sides of the equation:

$-6p = 6-8\\-6p = -2$

We divide by -6 on both sides of the equation:

$p = \frac {-2} {- 6}\\p = \frac {1} {3}$

Answer:

$p = \frac {1} {3}$

Plzzz helpppp!!!!!<br>How can you identify the solution to a system of inequalities?

VladimirAG [237]

Answer:

The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system. Graph one line at the time in the same coordinate plane and shade the half-plane that satisfies the inequality

Rhombus ADEF is inscribed into a triangle ABC so that they share angle A and the vertex E lies on the side BC . What is the leng

Thepotemich [5.8K]

Answer:

Length of side of rhombus is $x=\frac{ab}{a+b}$

Step-by-step explanation:

Given Rhombus ADEF is inscribed into a triangle ABC so that they share angle A and the vertex E lies on the side BC. We have to find the length of side of rhombus.

It is also given that AB=a and AC=b

Let side of rhombus is x.

In ΔCEF and ΔCBA

∠CEF=∠CBA (∵Corresponding angles)

∠CFE=∠CAB (∵Corresponding angles)

By AA similarity rule, ΔCEF~ΔCBA

∴ their sides are in proportion

$\frac{EF}{AB}=\frac{CF}{AC}$
