Answer:

Step-by-step explanation:

P = 480

P = 2 length + 2 width

but we also know that

2width = length

so plug that into the length

P = 2(2width) + 2 width

480 = 4 width + 2 width

480 = 6 width

80 = width

160= length

see?

    ¹/₄                                        25%                                         0.25

    ¹/₂                                        50%                                           0.5

    ²/₃                                      66.6%                                        0.6

Fraction;

25/100 = 1/4

66.6/100 = 2/3

Percentage

1/5 * 100 = 20%

1/2 * 100 = 50%

Decimal

1/5 = 0.2

25/100 = 0.25

1/2 = 0.5

Which equations are true for x = –2 and x = 2? Check all that apply.
Katyanochek1 [597]

Hi Brainiac


x² - 4 = 0

Add 4 to both sides

x² - 4 + 4 = 0 + 4

x² = 4

Now take the square root

x= +/-√4

x= 2 or x= -2

The answer is A


I hope that's help :)

<h3>¿Qué es una proporción?</h3>

Una proporción es una fracción de la cantidad total, y puede ser encontrada por intermedio de una regla de tres.

En este problema, la regla de tres es dada por:

15 dólares - 8 envíados

300 dólares - n envíados

Aplicando multiplicación cruzada:

15n = 300 x 8

n = (300 x 8)/15

n = 160

Luis enviará 160 dólares a su familia.

16x-4=31+12x please help I'm so confused
kolezko [41]
By the way I looked this up but heres the best ive got
<span>Simplifying (-1x + 27) + (16x + 4) = 0 Reorder the terms: (27 + -1x) + (16x + 4) = 0 Remove parenthesis around (27 + -1x) 27 + -1x + (16x + 4) = 0 Reorder the terms: 27 + -1x + (4 + 16x) = 0 Remove parenthesis around (4 + 16x) 27 + -1x + 4 + 16x = 0 Reorder the terms: 27 + 4 + -1x + 16x = 0 Combine like terms: 27 + 4 = 31 31 + -1x + 16x = 0 Combine like terms: -1x + 16x = 15x 31 + 15x = 0 Solving 31 + 15x = 0 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-31' to each side of the equation. 31 + -31 + 15x = 0 + -31 Combine like terms: 31 + -31 = 0 0 + 15x = 0 + -31 15x = 0 + -31 Combine like terms: 0 + -31 = -31 15x = -31 Divide each side by '15'. x = -2.066666667 Simplifying x = -2.066666667</span>

Determine whether the graphs of y=6x+4 and y=1/6x are perpendicular.
Alexxandr [17]

In this question, you're trying to see if the equations are perpendicular.

With the given equations, they are NOT perpendicular.

Why are they not perpendicular? This is because in order for two equations to be perpendicular from each one, one has to have a positive slope and the other has to have a negative slope, they pretty much have to be opposite from each other. One of them has to be the reciprocal.
