A rectangle's length is 8 inches more than three times the width. If the perimeter is 128 inches, what are the rectangle's dimen

nordsb [41]

Length (L): 3w + 8

width (w): w

Perimeter (P) = 2L + 2w

128 = 2(3w + 8) + 2(w)

128 = 6w + 16 + 2w

128 = 8w + 16

112 = 8w

14 = w

Length (L): 3w + 8 = 3(14) + 8 = 42 + 8 = 50

Answer: width = 14 inches, length = 50 inches

Which of the following is an arithmetic sequence?

enot [183]

Answer:

The third sequence.

Step-by-step explanation:

In an arithmetic sequence, the difference between two consecutive terms is the same.

For each option, find the difference between consecutive terms:

First option:

$4 - 2 = 2$ .
$8 - 4 = 4$ .
$16 - 8 = 8$ .

The differences are not the same. As a result, this option is not an arithmetic sequence.

Second option:

$4 - 12 = -8$ .
$\displaystyle \frac{4}{3} - 4 = -\frac{8}{3}$ .
$\displaystyle \frac{16}{3} - \frac{4}{3} = \frac{12}{3} = 4$ .

The differences are not the same. As a result, this option is not an arithmetic sequence, either.

Third option:

$\displaystyle -\frac{1}{2} - \frac{1}{2} = -1$ .
$\displaystyle -\frac{3}{2} - \left(-\frac{1}{2}\right) = -\frac{3}{2} + \frac{1}{2} = -1$ .
$\displaystyle -\frac{5}{2} - \left(-\frac{3}{2}\right) = -\frac{5}{2} + \frac{3}{2} = -1$ .

The differences are all $-1$ . As a result, this option is indeed an arithmetic sequence. Its common difference is $(-1)$ .

Fourth option:

$\displaystyle -\frac{1}{2} - \frac{1}{2} = -1$ .
$\displaystyle \frac{1}{2} - \left(-\frac{1}{2}\right) = \frac{1}{2} + \frac{1}{2} = 1$ .
$\displaystyle -\frac{1}{2}\right - \frac{1}{2} = -1$ .

The differences are varying between $1$ and $-1$ . As a result, this option is not an arithmetic sequence.

Solve for x and y. they both have to be the same number for each equation

Elis [28]

Hey there! :D

y=2x-9

We can plug that in as y, since y is equal to 2x-9.

5x-3(2x-9)= 23

Distribute.

5x-6x+27= 23

-1x+27=23

Subtract 27 on both sides.

-1x=-4

Divide both sides by -1.

x=4

Now, plug that in for y.

y=2(4)-9

y=8-9

y=-1

(4,-1) <== solution

I hope this helps!
