ANSWER: 1 SOLUTION

Step 1: Subtract 2x-1 from both sides.

x2−(2x−1)=2x−1−(2x−1)

x2−2x+1=0

Step 2: Factor left side of equation.

(x−1)(x−1)=0

Step 3: Set factors equal to 0.

x−1=0 or x−1=0

x=1

Answer:

x=1

Luden [163]

Answer:

7 milk chocolate

19 dark chocolate

Step-by-step explanation:

It is 2950 ounces in total, and dark chocolate is 100 ounces per bar and milk chocolate is 150 ounces per bar. There are 12 more dark chocolate bars so I multiplied 12 by 100 and that was 1,200. Then I took 2,950-1200=1,750. From there I subtracted 150 and 100 till I got to 0.

If the perimeter of this triangle is to be no more than 77 feet, write an inequality and

Sergio039 [100]

Given:

Consider the sides of the triangle are 4x+10, 2x-5 and 18 (in feet).

Perimeter of this triangle is to be no more than 77 feet.

To find:

The inequality and solution of the inequality.

Solution:

Perimeter of a triangle is the sum of all side.

Perimeter of given triangle $=(4x+10)+(2x-5)+18$

Perimeter of this triangle is to be no more than 77 feet. It means perimeter must be less than or equal to 77.

$(4x+10)+(2x-5)+18\leq 77$

$(4x+2x)+(10-5+18)\leq 77$

$6x+23\leq 77$

$6x\leq 77-23$

$6x\leq 54$

Divide both sides by 6.

$x\leq \dfrac{54}{6}$

$x\leq 9$

Therefore, the required inequality is $(4x+10)+(2x-5)+18\leq 77$ and the solution is $x\leq 9$ .

Can anyone tell me what the midpoint of PQ is?

melisa1 [442]

The formula of the midpoint of PQ:
$\left(\dfrac{x_P+x_Q}{2};\ \dfrac{y_P+y_Q}{2}\right)$

We have P(0; 0) and Q(2a; 0). Substitute:
$\left(\dfrac{0+2a}{2};\ \dfrac{0+0}{2}\right)=(a;\ 0)$
