How who u solve 5+2(x-3)

Answers

Answer 1

Answer: 5+2(x-3)
First you do everything in the parentheses.
2 times x= 2x
2 times -3=-6
Now you have 5 + 2x- 6
5 plus -6=-1
Now you have 2x-1=0
Add the -1 to both sides.
2x-1+1=0+1
Now simplify that to get: 2x=1
Now you divide each side by 2 to get x by itself.
So, x= 1/2

Answer 2

Answer: To solve 5+2(x-3), you must do the following...

You must use the distributive property to get an answer.

So, 2(x-3), correct? Okay, so first you multiply 2 times x, which would give you:

2x

Then you multiply 2 times 3, which gives you 6.

So now, you have 5+2x-6 - (Basically, we just extended the problem.)

Then we just simplify, which gives you... (drumroll please...?) 2x-1.

Hope this helps!

What all the numbers that round to 50?

Answers

The numbers that you could round to 50 (when rounding to a number that ends in 0) would be 45, 46, 47, 48, and 49. If you are rounding a decimal number to a whole number, then any number between 49.5 and 49.9 would round up to 50. Hope this helped! :D

Answer: Question: 403 × 581 = 234,143 See more below

Step-by-step explanation:

Estimate: 240,000

Because234,143 is greater than 240,000

-------------------------------------------------------------------------------------

TIPS

And, 48 49 50 51 52 53 and 50 round to 50
Round 50 to the last nearest to 5 or 50
For example, 45 rounds to 50

-------------------------------------------------------------------------------------

So,234,143 is underestimate to 240,000

twice a number plus another number is 310. The difference between the two numbers is 55. What are the two numbers

Answers

t us assume the two numbers to be "x" and "y".
Then
2x + y = 310
And
x - y = 55
Let us take the second equation and find the value of x in relation to y.
x - y = 55
x = y + 55
Now let us put the value of x in the first equation, we get
2x + y = 310
2(y + 55) + y = 310
2y + 110 + y = 310
3y = 310 - 110
3y = 200
y = 200/3
= 66 2/3
Now putting the value of y in the second equation, we get
x - y = 55
x - (200/3) = 55
3x - 200 = 55 * 3
3x = 165 + 200
x = 365/3
= 121 2/3
So the value of x is 121 2/3 and the value of y is 66 2/3

lets say the first number is x and the second y

twice the first number is 2x plus another number (y) =310
the difference of the numbers (x-y) = 55
we have simultaneous equations here:
2x+y=310
x-y=55

to cancel the y's the signs are different so you add the equations to give
3x=365
divide it by 3 to get:
x=121 and 2/3

using the easier equation x-y=55 we know x=121 2/3
now we substitute to get 121 2/3 -y=55
take 121 2/3 from both sides to get:
-y= -66 2/3
therefore y= 66 2/3

that means x=121.6(recurring) and y= 66.6(recurring)

Which of the following represents exponential growth? $y = 2x + 5$
$y - x = 4$
$x = 3$
$y = 5 * 2^(x)$
