The better buy will be 2.50lbs. Of turkey for $6.25 because when diving the price into the pounds the first buy will cost more than the second buy for each pound.

Answer:

Step-by-step explanation:

By order of PEMDAS, perform math within parentheses first.

$(28 - 19) \div 3$

Continue with PEMDAS

$(9) \div 3$

Now, simply divide

$9 \div 3 = 3$

Solve the inequality: 4(2x-11) is less than equal to -12 + 2(x-4) No "files" please and also need an explanation

dezoksy [38]

$4(2x-11) \leq -12 +2(x-4)\\\\\implies 8x - 44 \leq -12 + 2x -8\\\\\implies 8x -44 \leq 2x -20\\\\\implies 4x - 22 \leq x - 10~~~~~~~~~~~~~~~~~~~;[\text{Dividing both sides by 2}]\\\\\implies 4x -22 +22 \leq x -10 +22~~~~~~;[\text{Adding 22 to both sides}]\\\\\implies 4x \leq x+12\\\\\implies 4x -x \leq x+12-x~~~~~~~~~~~~~~~~;[\text{Subtracting x from both sides}]\\\\\implies 3x \leq 12\\\\\implies x \leq 4 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~;[\text{Dividing both sides by 3}]$

Subtract.<br>(3x²+7) - (3x - 2)

alekssr [168]

Answer:

3 • (x2 - x + 3)

Step-by-step explanation:

Step 1 :

Equation at the end of step 1 :

(3x2 + 7) - (3x - 2)

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

3x2 - 3x + 9 = 3 • (x2 - x + 3)

Trying to factor by splitting the middle term

3.2 Factoring x2 - x + 3

The first term is, x2 its coefficient is 1 .

The middle term is, -x its coefficient is -1 .

The last term, "the constant", is +3

Step-1 : Multiply the coefficient of the first term by the constant 1 • 3 = 3

Step-2 : Find two factors of 3 whose sum equals the coefficient of the middle term, which is -1 .

-3 + -1 = -4

-1 + -3 = -4

1 + 3 = 4

3 + 1 = 4

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

3 • (x2 - x + 3)
