John wrote that 5+5=10. Then he wrote that 5+5+n=10+n. Are the equations John wrote equivalent? Explain (in your solution justify by stating what property of equality he used).

Answers

Answer 1

Answer:

They are equivalent

Step-by-step explanation:

n would equal the same, and 10 and 5+5 equal the same. Therefore, whatever n is, they will be equal no matter what. Unless you subtract the n from one side and add on the other.

0.1(0.5m+6)=2

Answers

Answer:

m = 28

Step-by-step explanation:

The given expression is :

0.1(0.5m+6)=2

Step 1.

Use distributive property:

0.1(0.5m) +0.1(6) = 2

0.05 m+ 0.6 = 2

Step 2.

Subtract 0.6 both sides

0.05 m+ 0.6 -0.6= 2 -0.6

0.05 m = 1.4

or

0.5 m = 14

Step 3.

Divide both sides by 0.5

[tex]m=\dfrac{14}{0.5}\\\\m= 28[/tex]

Gabi's third step is not correct. It should be m = 28 instead of m = 7.

I need help with this question

Answers

Option A is the answer

The graph represents function 1, and the equation represents function 2:

Function 2
y = 5x + 4
How much more is the rate of change of function 2 than the rate of change of
function 1? (4 points)

Answers

Primarily, horizontal lines mean zero slope. Therefore the equation is y= 3 because you are only left with the y-intercept at this point. The rate of change is another way of saying slope. Function 2's slope is 5 and function 1's slope is 0. Therefore, the rate of change of function 2 is greater than the rate of change of function 1 by 5.  

5 is the answer.

The Mean Value of a Data Set

The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:

[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]

Where xi is the value of each data and n is the total number of values.

We are given the average weight of n=5 marathon runners:

[tex]\bar x=92[/tex]

Multiplying the formula by n and expanding the sum:

[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]

We are given the weighs of four of the runners:

[tex]5*92=89+95+90+90+x_5[/tex]

[tex]460=364+x_5[/tex]

Solving for x5:

Renting roller blades costs a flate fee of $5 plus an additional $2.50 per hour. Write a linear equation that models this.

Answers

Answer:

Linear equation : y = 2.50h + 5

Step-by-step explanation:

Given that:

Fee for renting roller blades = $5

Per hour charges = $2.50

Let,

h be the number of hours roller blades were rented

y be the total amount

Total amount = Per hour charges * Number of hours + Flat fee

y = 2.50h + 5

Hence,

Linear equation : y = 2.50h + 5

Diane buys candy that costs $4 per pound. She will spend more than $20 on candy. What are the possible numbers of pounds she will buy?
Use
P
for the number of pounds Diane will buy.
Write your answer as an inequality solved for p.​

Answers

Answer:

12 pounds

Step-by-step explanation:

We know that the candy costs $4 per pound

We also know that he will only spend up to $48

We can represent this as an equation:

4x = 48

Where as x = number of pounds

Solve the equation to find how many pounds he can buy.

4x = 48

Divide both sides by 4

x = 12

This means that Kareem can buy 12 pounds

Chase thought that only 23 people Would come to the banquet but 48 people endd up coming what was his percent error

Answers

Answer:

the percent of people that end up coming as error is 12%

Chase made a miscalculation of 52.08% percent.

What is Percentage Error?

The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.

Given that, Chase anticipated that just 23 people would attend the event; however, 48 individuals showed up.

The general formula for percentage error:

Percentage Error(%e) = ((Estimated Number – Actual Number)/ Actual number) x 100.

Hence,

Percentage error done by chase = (23 - 48) * 100/48

Percentage error done by chase = -52.08%

Therefore, the Percentage error done by chase is 52.08%
