Solve l=14j+3k for j.

1 answer:

3 0

L = 14j + 3k
l - 3k = 14j
(l - 3k) / 14 = j
j = (l - 3k) / 14 (Flipped sides for aesthetics. I like having the thing I solve for on left, but that is completely optional)

Answer:

I believe your answer is C 94.79

If this answer is wrong please let me know my apologies

Step-by-step explanation:

If my math is correct

44.50+44.50=89

Now, find the tax value by multiplying tax rate by the before tax price:

tax = 85 × 0.065

tax = 5.53 (tax value rounded to 2 decimals)

Add tax to the before tax price to get the final price:

The final price including tax = 85 + 5.53 = 90.53

90.53 plus the shipping 3.89=94.79

Here are the first 4 terms in the sequences

balu736 [363]

A series of numbers called an arithmetic progression or arithmetic sequence has a constant difference between the terms.

An arithmetic progression with a common difference of 2 is found, for instance, in the numbers 5, 7, 9, 11, 13, and 15. Given that each term has a common difference, this is an arithmetic sequence.

In this instance, the result is obtained by adding 6 6 to the prior term in the sequence.

What is the arithmetic progression formula?

a {n}=a {1}+(n-1) The nth term in the series is d a n.

The first term in the sequence is a 1.

d is the common distinction between the terms.

Answer: y = -1/2

Step-by-step explanation:

Subtract both sides by 7/8

y = 3/8 - 7/8

Then combine like terms

y = -4/8

Then simplify

y = -1/2

3x + 2y + z = 8 2x - 3y + 2z = -16 x + 4y - z = 20

I'll do a similar problem, and I challenge you to do this on your own using similar methods!

x+5y+2z=23
8x+4y+3z=12
9x-3y-7z=-10

Multiplying the first equation by -8 and adding it to the second one (to get rid of the x) and also multiplying the first equation by -9 and adding the third one to get rid of the x there too, we end up with

-36y-13z=-92
and
-48y-25z=-217

Multiplying both equations by -1, we get
36y+13z=-92
48y+25z=217

Multiplying the (new) first equation by -4/3 and adding it to the second (to get rid of the y), we get
(7+2/3)z=94+1/3

Dividing both sides by (7+2/3) to separate the z, we get
z= $\frac{282/3}{23/3} = \frac{282}{23}$

Plugging that into
48y+25z=217, we can subtract 25z from both sides and divide by 48 to get
$y= \frac{217-25z}{48} =\frac{217-25*282/23}{48}$

Lastly, we plug this into x+5y+2z=23 to get
x=23-5y-2z by subtracting 5y+2z from both sides to get
$x=23- \frac{217-25*282/23}{48}*5-2*282/23$

Good luck, and feel free to ask with any questions!

PLEASE HELP!!!!!

garri49 [273]

Translated left three (x-3) and down two (y-2) gives you.

(-7,3), (-7, -3), (-4, -1)

So False.
