Is the equation always sometimes or never true . . 15+2x-4=9x+11-7x. . 2x+3(4x-1)=2(5x+3)+4x

1 answer:

4 0

15 + 2x - 4 = 9x + 11 - 7x is always true. You can prove this by plugging in random values for x. I plugged in x = 0, (11=11), and x=1 (13=13).

2x + 3(4x-1) = 2(5x+3) = 4x is never true. When you try to solve for x, the x disappears.

2x +12x - 3 = 10x + 6 + 4x

14x - 3 = 14x + 6

-3 = 6 Not possible.

Factor the difference of the perfect square. If the binomial will not factor, write prime.

HELP When 2((Three-fifths x + 2 and three-fourths y minus one-fourth x minus 1 and one-half y + 3)) is simplified, what is the r

lesya692 [45]

Answer:

<h2> StartFraction 7 over 10 EndFraction x + 2 and one-half y + 6</h2>

Step-by-step explanation:

Given the expression $2(\frac{3x}{5}+2\frac{3y}{4}-\frac{x}{4}-1 \frac{1}{2}y+3)$

To simplify the expression, we need to first collect the like terms of the functions in parentheses as shown;

$= 2(\frac{3x}{5}-\frac{x}{4}-1 \frac{1}{2}y+2\frac{3}{4}y+3)\\= 2(\frac{3x}{5}-\frac{x}{4}- \frac{3}{2}y+\frac{11}{4}y+3)\\$

Then we find the LCM of the resulting function

$= 2(\frac{3x}{5}-\frac{x}{4}- \frac{3}{2}y+\frac{11}{4}y+3)\\= 2(\frac{12x-5x}{20} - (\frac{6y-11y}{4})+3)\\= 2(\frac{7x}{20}- (\frac{-5y}{4})+3 )\\= 2(\frac{7x}{20}+ \frac{5y}{4}+3 )\\= \frac{7x}{10} + \frac{5y}{2} +6\\= \frac{7x}{10} + 2\frac{1}{2}y+6\\$

The final expression gives the required answer
