Mathematics

Step-by-step explanation:

Step 1:  After adding 875 to both sides of the original equation, you get

x^2+10x+\text{ ----- }=875

Step 2: <em>b</em> is the coefficient of the <em>x</em> term, so <em>b</em> = 10.  Divide in half (always half for completing the square!).

\frac{10}{2}=5

Square that result to get 25.  That's <em>c</em>, the amount to add to both sides of the equation.

Step 3:  Adding <em>c</em> to both sides produces

x^2+10x+25=875+25

Step 4: The result of Step 3 is x^2+10x+25=900, and the left side factors as a perfect square.

(x+5)^2=900

Step 5: After taking square roots of both sides, you get

x+5=\pm 30  which represents "two equations in one."

Separate them.

x+5=30 \text{ or } x+5 =-30\\x=25 \text{ or } x=-35

A store owner wants to develop a new snack mix by mixing chocolate and trail mix. How many pounds of chocolate costing $13.20 pe
Stells [14]

Answer:

13lbs

Step-by-step explanation:

x = number of pounds of chocolate/lbs

13.20(x) + 3.90(10) = 9.16(x + 10)

13.2x + 39 = 9.16x + 91.6 (x100)

1320x + 3900 = 916x + 9160

404x = 5260

x = 1315/101 = 13.0198.... ⇒ 13lbs

Jadyn prepares a bag of candy before a road trip. The bag contains individual pieces of Skittles, M&amp;Ms, Life Savers and Sour
kipiarov [429]

Given condition is- The bag contains individual pieces of Skittles, M&Ms, Life Savers and Sour Patch Kids.

Let the total number of candies in the bag be = x

Then, Skittles are \frac{1x}{2}

Candies left = x-\frac{x}{2} = \frac{x}{2}

M&Ms are = \frac{1x}{8}

Now remaining candies are= \frac{3x}{8}

Now Life savers are = \frac{9x}{32}

Now adding all these 3 candies

\frac{x}{2}+ \frac{x}{8}+\frac{9x}{32}

=\frac{29x}{32}

Now the remaining candies sour patch will be =

x-\frac{29x}{32} =\frac{3x}{32}

Hence, sour patch kids are \frac{3}{32}
