Celia uses the steps below to solve the equation Negative StartFraction 3 over 8 EndFraction (negative 8 minus 16 d) + 2 d = 24.

Step 1 Distribute Negative StartFraction 3 over 8 EndFraction over the expression in parentheses. 3 minus 16 d + 2 d = 24 Step 2 Simplify like terms. 3 minus 14 d = 24 Step 3 Subtract 3 from both sides of the equation. Negative 14 d = 21 Step 4 Divide both sides of the equation by –14. D = StartFraction 21 over negative 14 EndFraction = Negative three-halves = negative 1 and one-half Which corrects the error in the step in which Celia made the first error?

Answer:

Celia made the first error in the Step 1

<h3><u>Celia's error in step 1 is  </u></h3>

Distribute Negative Start Fraction 3 over 8 End Fraction over the expression in parentheses. -\frac{3}{8}(-8)-\frac{3}{8}(-16d)+2d=24

3-16d+2d=24

<h3><u>The corrected step 1 is </u></h3>

By using the distributive property a(x+y)=ax+ay  

Step 1 -\frac{3}{8}(-8)-\frac{3}{8}(-16d)+2d=24

3+6d+2d=24

Step-by-step explanation:

Celia uses the equation is  Negative Start Fraction 3 over 8 End Fraction (negative 8 minus 16 d) + 2 d = 24.

It can be written as

<h3> Now Celia uses the steps below to solve the given equation :</h3>

-\frac{3}{8}(-8-16d)+2d=24

Step 1 Distribute Negative Start Fraction 3 over 8 End Fraction over the expression in parentheses. -\frac{3}{8}(-8)-\frac{3}{8}(-16d)+2d=24

       3-16d+2d=24

Step 2 Simplify like terms 3-14d=24

Step 3 Subtract 3 from both sides of the equation 3-14d-3=24-3

Step 4 -14d=21

Step 5 d=\frac{21}{-14}

Step 6 d=-(\frac{-3}{2})

Step 7 d=-(1\frac{1}{2})

<h3>The corrected steps are</h3>

-\frac{3}{8}(-8-16d)+2d=24

By using the distributive property a(x+y)=ax+ay  

Step 1 -\frac{3}{8}(-8)-\frac{3}{8}(-16d)+2d=24 3+6d+2d=24

Step 2 Simplify the like terms  3+8d=24

Step 3 Subtract 3 from both sides of the equation 3+8d-3=24-3

Step 4 8d=21

Step 5 d=\frac{21}{8}

Step 6 d=2\frac{5}{8}  

<h2>Celia made the first error in the <u>Step 1 </u>Celia's error in step 1 is  </h2>

Distribute Negative Start Fraction 3 over 8 End Fraction over the expression in parentheses. -\frac{3}{8}(-8)-\frac{3}{8}(-16d)+2d=24

       3-16d+2d=24

<h2><u>The corrected step 1 is </u></h2>

By using the distributive property a(x+y)=ax+ay  

Step 1 -\frac{3}{8}(-8)-\frac{3}{8}(-16d)+2d=24

3+6d+2d=24

Mademuasel [1]
If Cassie has 20 and wants to keep 11 then we would subtract 11 from 20.

So 20 - 11 is 9.

Her sister will get 9 bracelets.

Hope this helps!

A stock has produced returns of 11.9 percent, 5.6 percent, 16.4 percent, and -4.2 percent over the past four years, respectively
EleoNora [17]

The average annual return is

\displaystyle ((1+0.119)(1+0.056)(1+01.64)(1-0.042))^{\frac{1}{4}}-1=\sqrt[4]{1.317687706368}-1\\\\ \approx 7.14\%

Bald-faced hornets have a hive that is approximately cone-shaped, as shown in the image. One such hive has a radius of 15 inches
sineoko [7]

Answer:

Volume of the hive is 4712.4 square inches.

Step-by-step explanation:

Since hive has the shape of a cone with radius = 15 inches and height = 20 inches

Therefore, volume of the given cone = \frac{1}{3}(\text{Area of the base})\times \text{height}

Area of the circular base = πr²

Area = π(15)²

        = 225π

Volume of the cone = \frac{1}{3}(225\pi )\times{20}

                                 = 1500π

                                 = 4712.39

                                 ≈ 4712.4 square inches

Therefore, volume of the hive is 4712.4 square inches.
