Answer:

x ≈ 4.3

Step-by-step explanation:

<em><u>Distribute the 4 to (8x - 3) and the 5 to (x - 5), like so:</u></em>

4(8x - 3) - 30x = 5(x - 5)

32x - 12 - 30x = 5x - 25

<u><em>Add like terms (32x and -30x), like so:</em></u>

32x - 30x = 2x

2x - 12 = 5x - 25

<em><u>Subtract 2x from both sides:</u></em>

2x - 12 = 5x - 25

-2x         -2x

____________

-12 = 3x - 25

<em><u>Add 25 to both sides:</u></em>

-12 = 3x - 25

+ 25       + 25

____________

13 = 3x

<em><u>Divide both sides by 3:</u></em>

4.3 ≈ x

Answer:

x = 13/3

Step-by-step explanation:

4(8x-3) - 30x = 5(x-5)

Distribute

32x - 12 - 30x  = 5x -25

Combine like terms

2x -12 = 5x-25

Subtract 2x from each side

2x-12-2x = 5x-2x -25

-12 = 3x-25

Add 25 to each side

-12+25 = 3x-25+25

13 = 3x

Divide each side by 3

13/3 = x

NEED CORRECT ANSWER PLEASE! THANKS:)
-BARSIC- [3]
The answer is B. (2x + 5)(x + 1)You could answer this by expanding each answer until you found one that matched 2x^2 + 7x + 5, but I will only show how the answer expands:
2x × x = 2x^2
5 × x = 5x
2x × 1 = 2x
5 × 1 = 5

So in total those brackets expand to 2x^2 + 7x + 5. I hope this helps!

How many positive 3-digit numbers are divisible by 11?
enyata [817]

Answer:

81

Step-by-step explanation:

If a number is divisible by 11, then you can make those numbers by multiplying 11 by any number. Like 33 is divisible by 11 because 3×11 is 33.

Of course, 33 is too small, we are looking for 3-digit numbers...
