Slove for x: x+1/3=1/4

Mathematics
1 answer:

Hey!


To solve this problem, we must subtract one over three from both sides of the equation. This will give us x on its own.

<em>Original Equation :</em>
x + \frac{1}{3} = \frac{1}{4}

<em>New Equation {Added Subtract \frac{1}{3} to Both Sides} :</em>
x + \frac{1}{3} - \frac{1}{3} = \frac{1}{4} - \frac{1}{3}

<em>Solution {New Equation Solved} :</em>
x=- \frac{1}{12}

<em>So, this means that in the equation provided</em>,  x=- \frac{1}{12}.

Hope this helps!

Y = x and y =x^2 - 2
maxonik [38]

Answer:

  (-1, -1) and (2, 2)

Step-by-step explanation:

Substitute for y in the first equation and solve the quadratic.

  x = x^2 -2

  x^2 -x -2 = 0  . . . . subtract x

  (x -2)(x +1) = 0 . . . .factor

Solutions are the values of x that make these factors be zero:

  x = 2, x = -1

Since y=x, the solutions are ...

  (x, y) = (-1, -1) and (2, 2)

bulgar [2K]

Complete Question:

To create a bulletin board, Maryann is planning to stretch fabric from burlap sacks over cardstock. She collects 6 kg of burlap sacks. The area density of the burlap is 0.4 kg/m².

Maryann's friends loved her bulletin board , and 4 of them asked her to make one for their homes. She offered to make each of her friends a replica of her bulletin board that measures 2 meters by 3 meters . How many kilograms of burlap should Maryann collect to complete the bulletin boards for her friends?

Answer:

To complete the bulletin boards for her friends, Maryanne should collect 6 kg of burlap more

Step-by-step explanation:

Mass of burlap sacks that Maryann collects = 6 kg

Area density of burlap = 0.4 kg/m²

Area Density = Mass / Area........(1)

The Area of bulletin board that can be made with the 6 kg of burlap sand can be calculated by using equation (1)

0.4 = 6 / Area

Area = 6/0.4

Area of bulletin board that can be made from 6 kg= 15 m² of bulletin board  

The area of bulletin board that Maryann made for herself = 2 * 3 = 6m²

To make similar bulletin boards for her four friends, the total area of bulletin board made for her 4 friends = 6 * 4 = 24m²

To calculate the mass of burlap required to make a 24m² bulletin board, use equation (1)

0.4 = Mass / 24

Mass = 0.4 * 24

Mass = 9.6 kg

The mass of burlap used to make Maryann's bulletin board alone:

0.4 = Mass/6

Mass = 2.4 kg

Out of the 6kg that she got, she has used 2.4 kg for herself

The remaining mass of burlap = 6 - 2.4 = 3.6 kg

Therefore, to complete the bulletin board for her friend, she should collect (9.6 - 3.6) = 6 kg of bulletin more

PRECAL <br><br>Find the compliment of 0.25<br><br>Find the supplement of 7π/8
balandron [24]
The unit of measurement is not specified, so for the sake of this problem, we'll assume it's radians (If you need it in degrees, I'll be happy to edit).

Find the compliment of 0.25:

Complementary angles add up to 90 degrees. In radians, this would be π/2. If you're unsure how I got this, check degrees to radian conversions.

The compliment of 0.25 would be \dfrac{\pi}{2} - \dfrac{1}{4} (1/4=0.25)

\dfrac{\pi}{2} - \dfrac{1}{4}

= \dfrac{\pi}{2} - \dfrac{1}{4} = \dfrac{2\pi-1}{4}

(This is the simplified form in case you're homework needs it in this form)

That's the compliment. In decimal (rounded to the nearest hundredth), this would be 1.32 radians.

Find the supplement of 7π/8:

Supplementary angles add up to 180 degrees. In radians, this would be π.

The supplement would be the following:

\pi- \dfrac{7\pi}{8}

=\dfrac{8\pi}{8}-\dfrac{7\pi}{8}=\dfrac{\pi}{8}

Thus, the supplement is π/8 radians. If any of this struck you as confusing, comment and I'd be happy to clarify.
