| 2p -1 | =45, what are the values of p?
Alex73 [517]

Answer:

p = 23       and p = -22

Step-by-step explanation:

| 2p -1 | =45

Absolute value equations have 2 solutions, one positive value and one negative

2p-1 = 45    and 2p-1 = -45

Add 1 to all sides

2p-1+1 = 45+1    and 2p-1+1 = -45+1

2p = 46                        2p = -44

Divide by 2

2p/2 = 46/2    and   2p/2  = -44/2

p = 23       and p = -22

Find 3 consecutive integers such that twice the first, plus three times the second, plus four times the third is 20. Please show
Neporo4naja [7]
Since the integers are consecutive, you could call them 'x', x+1,and x+2.
Or you could all them  x-1, 'x', and x+1.
Or you could call them  x-2, x-1, and 'x'.
It's up to you.  Each of those sets describes 3 consecutive numbers.

Most people will call them 'x', x+1, and x+2, so let's do that.

Now just go through the question and make the quantities it talks about:

"twice the first" . . . . 2(x)
"three times the second" . . . . 3(x+1)
"four times the third" . . . . . 4(x+2)

and finally, it says that the sum of those things is 20.
This should not be a major problem.

2x + 3(x+1) + 4(x+2) = 20

You can probably handle it from here, but I'll continue anyway.
The next thing to do is take out all the parentheses:
3(x+1) = 3x + 3
4(x+2) = 4x + 8
Now add up the whole thing again, but without parentheses:

2x + 3x + 3 + 4x + 8 = 20

Gather all the x's together, and all the naked numbers together:

(2x + 3x + 4x) + (3 + 8) = 20

Addum up:   9x + 11 = 20

Subtract 11 from each side:   9x = 9

Divide each side by  9 :     x = 1

The first integer = x . . . . . . . <em>1</em>
The second integer = x+1 . .<em> . 2</em>
The third integer = x+2 . . . . .<em> 3 </em>

<u>Check:</u>

"twice the first" . . . . . . . . . . 2(1) = 2
"three times the second". . . 3(2) = 6
"four times the third" . . . . . . 4(3) = 12

Addum up:  2 + 6 + 12 = 20 just like the question said.      yay!

Mikkel pays a 4 percent state income tax on his earnings. If he earns $1,867, how much state income tax can he expect to pay? $4
lisabon 2012 [21]

Answer:

$74.68

Step-by-step explanation:

Convert the percent to a decimal.

4% = 0.04

Multiply his income by the percentage to find the tax.

$1,867 × 0.04 = $74.68

He can expect to pay $74.68.
