Mathematics

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

The base of a triangle is 2 more than twice the height of the triangle. Find the measure of the base and the height if the area
vekshin1
B = 2 + 2H 
A = 20 ft^2
H = H

Since the Area of a Triangle is Base * Height then the formula should be:
A = BH
20 = H(2+2H)
20 = 2H^2 + 2H
0 = 2H^2 + 2H - 20 

Find the zeros of the quadratic equation through substituting the values of a,b, and c. You will get the zeros of x = 2.7 and -3.7. The only thing that would make sense is you use the x=2.7 because there are no negative heights.

Since b = 2h+2 
b= 2(2.7) + 2
b= 5.4 + 2 
b=7.4

I don't know where you got 4 and 10, but what I got is different.

You and your brother are reading the same novel. You want to get ahead of him in the book, so you decide to read 303030 minutes
ddd [48]

You will read for 45 minutes if your brother reads for 15 minutes.

<em><u>Explanation</u></em>

You decide to read 30 minutes longer than your brother reads.

If your brother reads x number of minutes, then 30 minutes longer than x minutes means (x+30) minutes.

As the number of minutes you read is y , so the equation will be:  y= x+30

When your brother reads for 15 minutes, then we will just <u>plug x=15 into the above equation</u>. So.....

y=15+30= 45

So, you will read for 45 minutes if your brother reads for 15 minutes.

\frac{5}{2}x+\frac{1}{4}  +\frac{3}{4} x=\frac{1}{8} \\\\\frac{5}{2}(8)x+\frac{1}{4}  (8)+\frac{3}{4}(8) x=\frac{1}{8}(8)\\20x+2+6x=1\\20x+6x=1-2\\26x=-1\\\frac{26x}{26} =\frac{-1}{26} \\x=-\frac{1}{26}
