Answer: Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable. ... A variable need not be “x,” but might be “y,” "w," or any other letter, name, or symbol

Answer:

x = 16

Step-by-step explanation:

The triangle in question is an isosceles triangle which means :

m<Q = m<P and the sum of interior angles in a triangle is equal to 180

so we can find the value of x using the following equation:

5x - 2 + 3x + 3 + 3x + 3 = 180 add like terms

11x + 4 = 180 subtract 4 from both sides

11x = 176 divide both sides by 11

x = 16

-----------------------------\\\\
\cfrac{\textit{similar shape}}{\textit{similar shape}}\qquad \cfrac{s}{s}=\cfrac{\sqrt{s^2}}{\sqrt{s^2}}=\cfrac{\sqrt[3]{s^3}}{\sqrt[3]{s^3}}\\\\
-------------------------------\\\\$

$\bf \cfrac{small}{large}\qquad \cfrac{s}{s}=\cfrac{\sqrt[3]{s^3}}{\sqrt[3]{s^3}}\implies \cfrac{2}{7}=\cfrac{\sqrt[3]{32}}{\sqrt[3]{v}}\implies \cfrac{2}{7}=\sqrt[3]{\cfrac{32}{v}}\implies \left( \cfrac{2}{7} \right)^3=\cfrac{32}{v}
\\\\\\
\cfrac{2^3}{7^3}=\cfrac{32}{v}\implies v=\cfrac{7^3\cdot 32}{2^3}$

What is the quotient if <br> 1/3 of 10 is divided by 1/7 of 8/12? Reduce if possible.

MrMuchimi

Answer:

1/35

Step-by-step explanation:

1/3 of 10 (of means multiply)

1/3 times 10 is 10/3

1/7 of 8/12=2/21

2/21 divided by 10/3

use keep change flip

2/21 divided by 10/3 equals 2/21* 3/10

1/35 is the answer

HELP PLEASE, ITS DUE TODAY IN AN HOUR!!

Schach [20]

Answer:

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

If m > 0 , then line slopes upwards from left to right

If m < 0 , then line slopes downwards from left to right

y = 3x - 2

has m > 0 and c = - 2 , thus line slopes upwards crossing the y- axis at - 2

y = - 2x + 3

has m < 0 and c = 3, thus line slopes downwards crossing the y- axis at 3

on the graph this is the lower blue line and the red line

the solution to the system is at the point of intersection of the 2 lines

This is at point D
