Answer:

<u>Rounded:</u> 16.34

Step-by-step explanation:

The OG(original) mass is 23.9 grams.

30.4% is too high of the actual mass.

Find out 69.6% of 23.9.

Set up problem.

    x            69.6%                  

______ = ______

 23.9          100%

Find x.

69.6 x 23.9 = 1,663.44

1,663.44/100 = 16.344

= 16.344

Not sure if this is correct but I tried my best. :)

12. An equation is shown. 8 1/2 - 3 1/? = 5 3/12<br>What is the value of the missing number?​
weeeeeb [17]

Answer:

Step-by-step explanation:

Alright, lets get started.

8\frac{1}{2}-3\frac{1}{?}=5\frac{3}{12}

These are mixed number given.

Suppose the complete mixed number of second place is x.

Converting mixed numbers into fractions.

\frac{17}{2}-x=\frac{63}{12}

Adding x in both sides

\frac{17}{2}=x+\frac{63}{12}

x=\frac{17}{2}-\frac{63}{12}

Making common denominator

x=\frac{102}{12}-\frac{63}{12}

x=\frac{39}{12}

x=\frac{13}{4}

In mixed number form:

x=3\frac{1}{4}

So comparing with given equation, the '?' sign will be equal to 4.

Hence the answer is 4    :  Answer

Hope it will help :)

Which of these problem situations could best be modeled by the equation below? 52(18) + x = 1200 Debbie sold 52 boxes of fruit f
kirill [66]

Answer:

a) Debbie sold 52 boxes of fruit for $18 each plus a bonus x, for selling the boxes quickly. Find x, the bonus if Debbie sold the fruit quickly and earned $1200.

Step-by-step explanation:

The model equation is given as:

52(18) + x = 1200

a) Debbie sold 52 boxes of fruit for $18 each plus a bonus x, for selling the boxes quickly. Find x, the bonus if Debbie sold the fruit quickly and earned $1200.

52($18) + x = $1200

52(18) + x = $1200

Option a is correct

b) Katrina earned $18 plus a weekly bonus x, for managing her money wisely each week for 52 weeks. Find x, if Katrina earned $1200.

x = weekly bonus, hence, we have the equation:

$18 + (x)52 = $1200

Option b is wrong

c) Marissa has $52 in her savings account. She earns $18 for each lawn she mows. Find x, the number of weeks she needs to mow lawns in order to have a total of $1200.

This is represented as:

$52 + $18(x) = $1200

Option c is wrong

d) Edward had a balance of $52 in the bank. He added x dollars to his account last month. This week he deposited another $18. Find x, the amount Edward deposited in the bank last month if his total savings is now $1200.

This is represented as :

$52+ $x + $18 = $1200

Option d is wrong.

Therefore, the correct statement that modelled the equation is option a
