What’s 2-3-4-4+7. Plzzzz

nignag [31]

Answer:

-2

Step-by-step explanation:

Simplify the following:

2 - 3 - 4 - 4 + 7

2 - 3 - 4 - 4 + 7 = (2 + 7) - (3 + 4 + 4):

(2 + 7) - (3 + 4 + 4)

2 + 7 = 9:

9 - (3 + 4 + 4)

3 + 4 = 7:

9 - (7 + 4)

7 + 4 = 11:

9 - 11

9 - 11 = -2:

Answer: -2

Help, with solving rational equations! I am no good at it :( Solve for x: 2 over 5 plus 3 over 5 x equals quantity x plus 5 over

mamaluj [8]

If this is your equation: $\frac{2}{5} + \frac{3}{5x} = \frac{x+5}{10}$
Solution:
LCD for 5 and 5x is 5x
$\frac{x}{x} ( \frac{2}{5} )+ \frac{3}{5x} = \frac{x+5}{10}$
$\frac{2x}{5x} + \frac{3}{5x} = \frac{x+5}{10}$
$\frac{2x+3}{5x} = \frac{x+5}{10}$
$10(2x+3)=5x(x+5)$ ←cross product
20x + 30 = 5x² + 25x ←simplify with distributive property
0 = 5x² + 5x - 30 ←use inverse operations to collect all terms on one side
0 = x² + x - 6 ←if possible divide by numerical GCF (This case 5)
0 = (x + 3)(x - 2) ←Factor
x = -3 or x = 2
Please check by substitution in original equation... Both work
