Mona solved an equation incorrectly, as shown below:Step 1: 5x = 30
Step 2: x = 30 − 5
Step 3: x = 25

Which statement best explains why Step 2 is incorrect in Mona's solution?

She did not add 5 to 30.

She did not divide 30 by 5.

She did not multiply 30 by 5.

She did not multiply 30 five times.

Answer 1
Answer:

Answer:

Option 2nd is correct

She did not divide 30 by 5.

Step-by-step explanation:

As per the statement:

Mona solved an equation incorrectly, as shown below:

Step 1: 5x = 30

Step 2: x = 30 − 5

Step 3: x = 25

Step 2 is incorrect as she did not divide 30 by 5.

Correct steps for the equation are:

Step 1.

5x = 30

Step 2.

x = (30)/(5)

Step 3.

x = 6

Therefore, the statement which explains that Step 2 is incorrect in Mona's solution is, She did not divide 30 by 5.
Answer 2
Answer: Mona subtracted 5 where she should have divided 5. If the equasion was. x+5=30 then she would have subtracted 5.

Samir buys x cans of soda at 30 cents each and (x+4) cans of soda at 35 cents each. The total cost was $3.35. Find x

Answers

An equation is formed of two equal expressions. The value of x is 3.23.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The cost of x cans can be written as =x * 0.30

The cost of (x+4) cans can be written as,

(x+4) * 0.35\n= 0.35 x+ 1.4

Now, the total cost of the cans is given to us like $3.35, therefore, the value of x can be written as,

(0.30x) + 0.35x+ 1.4 = 3.35\n\n0.65x = 3.5-1.4\n\nx = (2.1)/(0.65)\n\nx = 3.23

Hence, the value of x is 3.23.

0.30x is the cost of the first type of soda. 0.35(x+4) is the cost of the second type of soda. Put these into an equation looking like:

Cost of Soda A + Cost of Soda B = Total Cost
0.30x + 0.35(x+4)=3.35 --> Expand 0.35(x+4)
0.30x + 0.35x + 1.4 = 3.35 --> Add the x's and subtract 1.4
0.65x = 1.95 --> Divide by 0.65
x = 3

Which of the following employees has the greatest total employee compensation?a.
Employee A: total job benefits $49,200 and total job expenses $300
b.
Employee B: total job benefits $49,500 and total job expenses $500
c.
Employee C: total job benefits $ 49,800 and total job expenses $700
d.
Employee D: total job benefits $50,100 and total job expenses $900

Answers

We have to choose the correct answer which of the employees has the greatest total employee compensation. We just have to subtract the job expenses from total job benefits for everyone of them. A: $49,200 - $300 = $38,900. B : $49,500 - $500 = $49,000. C : $49,800 - $700 = $41,100. D : $50,100 - $900 = $49,200. The largest sum is $49,200 ( employee D ) . Answer: The greatest total employee compensation has Employee D.
D: Employee D: Total employee benefits $3,000                        Total job benefits $52,300

The Polleys want to put in a swimming pool next summer. They need to save $6,000 over 12 months in order to achieve this goal. They set aside the same amount each month and after 7 months discovered they have saved $3,100. The Polleys know that they must adjust their plan in order to meet their goal, so they come up with the following options:Option A: Save the original amount each month but put the pool in one month later than originally planned.

Option B: Increase savings each month by $100 from their original plan

Answers

Answer:

Neither option A nor option B will allow them to meet their goal.

Step-by-step explanation:

Consider the provided information.

The Polleys want to put in a swimming pool next summer. They need to save $6,000 over 12 months in order to achieve this goal.

They set aside the same amount each month and after 7 months discovered they have saved $3,100. Now he left with 5 months (∴7+5=12 months)

Let x is the amount he was saving each month. He saved x amount for 7 months and after 7 months he has $3100.

7x=3100

x=442.86

He saved approximately $442.86 each month.

Option A Save the original amount each month but put the pool in one month later than originally planned.

That means the number of month he has now 5+1=6.

Now find how much he can save in 6 months if he save $442.86 per month.

6×442.86=2657.16

Now add his all savings as:

$3100+$2657.16=$5757.16

Thus, the option A will not allow him to meet his goal.

Now consider the option B) Increase savings each month by $100 from their original plan.

Previously he was saving $442.86 each month now increase this number by $100.

$442.86+$100=$542.86

In 5 months he can save:

5×542.86=$2714.3

Now add his all savings as:

$3100+$2714.3= 5814.3

Thus, the option B will not allow him to meet his goal.
