Simplify 2(5x – 4) + 3x

2 answers:

6 0

To simplify, you must distribute the 2 into the 5x and -4 by multiplying 2 with 5x and 2 with -4.

<span>2(5x – 4) + 3x

2 x 5x = 10x

2 x -4 = -8

You will get 10x - 8 + 3x

Now you must combine like terms or add like terms. In this case we must add 10x and 3x

10x + 3x = 13x

Finally the answer would be 13x - 8</span>

= 10x-8+3x (multiply 2 with (5x-4))
=13x-8 (then add 10x+3x will give you 13x)

Answer should be 13x-8

Hope this helps!

miley has d decks of playing cards. write an equation for a function that shows how many c cards miley has all together if each

anastassius [24]

Answer is C= 52d
To solve problems like this, you would just need to think about what the question is asking you one step at a time
List what you know
- There are 52 cards in each deck
- We need how many cards in total

So let us think about it from a mathematical standpoint
1 deck= 52 cards 1 x 52= 52
that means.....
2 deck= 104 cards 2 x 52 = 104
3 deck= 158 cards 3 x 52 = 158
and the list keeps going
That means that 52 multiplied by whatever number d is will get you the total number of cards.
thus C= 52d

Christopher deposit 1 dollar in the savings account earning 10 interest compounded annually to the nearest tenth,how much intere

Orlov [11]

Answer:

Step-by-step explanation:

The formula for determining compound interest is expressed as

B = p(1 + r)^t

where

B is the balance (final amount),

p is the principle (starting amount),

r is the interest rate.

t is the time in years.

From the information provided,

p = $1

r = 10% = 10/100 = 0.1

t = 3 years

The balance in 3 years would be

A = 1(1 + 0.1)^3

A = 1(1.1)^3

A = $1.331

The interest earned after 3 years is

1.331 - 1 = $0.331

Rounding up to the nearest tenth, it becomes $0.3

Given the points (4,-2) and (8,1), what is the equation of a line that connect the two points. Answer in slope-intercept form.

monitta

The equation of required line in slope-intercept form is:

$y=\frac{3}{4}x-5$

Step-by-step explanation:

We are given the points (4,-2) and (8,1) we need to find the equation of a line that connect the two points. We need to find equation of line in slope-intercept form.

The standard equation of slope-intercept form is:

$y=mx+b$
