Which of the following describes a correct method for solving the equation: -7/2n + 5= -16 A. Add 5 to both sides, then devide both sides by 2/7. B. Subtract 5 from both sides, then add 7/2 to both sides. C. Add -5 to both sides, then multiply both sides by -2/7. D. Subtract 5 from both sides , then multiply both sides by 7
Answers
Answer:
If the use the method ''Add -5 to both sides, then multiply both sides by -2/7'', we can get the value n = 6.
Thus, the correct option is 'C'.
Step-by-step explanation:
Given the equation
[tex]-\frac{7}{2}n+5=-16[/tex]
Let me solve this using the correct method
[tex]-\frac{7}{2}n+5=-16[/tex]
Add -5 to both sides
[tex]-\frac{7}{2}n+5+\left(-5\right)=-16+\left(-5\right)[/tex]
simplify
[tex]-\frac{7}{2}n=-21[/tex]
Multiply both sides by -2/7
[tex]-\frac{7}{2}n\times -\frac{2}{7}=-21\times -\frac{2}{7}[/tex]
simplify
[tex]n=6[/tex]
Therefore, if the use the method ''Add -5 to both sides, then multiply both sides by -2/7'', we can get the value n = 6.
Thus, the correct option is 'C'.

The average rate of change of g(x) over the interval [2, 8] is given by
(g (8) - g (2)) / (8 - 2)
In other words, it's the slope of the line through the points (2, g (2)) and (8, g (8)).
Use the definition of the function to evaluate it at the points in the numerator:
• 8 ≥ 4, so using the second piece, g (8) = -0.5(8) + 8 = 4
• 2 < 4, so g (2) = 5(2) + 1 = 11
Then the average rate of change is
(g (8) - g (2)) / (8 - 2) = (4 - 11) / 6 = -7/6

A beauty supply company has 5 gallons of 20% hydrogen peroxide solution on hand. The
company also has a nearly limitless amount of a solution that contains 30% hydrogen
peroxide. How many gallons of the 30% hydrogen peroxide solution should the company add
to the 20% hydrogen peroxide solution to obtain a mixture that is 23% hydrogen peroxide?
Write your answer as a whole number or as a decimal rounded to the nearest tenth.
Answers
Answer:
2.1 gallons
Step-by-step explanation:
Let V = volume of 20 % hydrogen peroxide = 5 gallons, V₁ = volume of 30 % hydrogen peroxide and V₃ = volume of 23 % hydrogen peroxide. So the final volume is V + V₁ = V₂
V₁ + 5 = V₂ (1)
Also, since quantity = concentration × volume,
Let Q = quantity of 20% volume hydrogen peroxide = 0.2V, Q₁ = quantity of 20% volume hydrogen peroxide = 0.3V₁ and Q₂ = quantity of 23% volume hydrogen peroxide = 0.23V₂
So, 0.2V + 0.3V₁ = 0.23V₂
0.2 × 5 + 0.3V₁ = 0.23V₂
1 + 0.3V₁ = 0.23V₂
0.3V₁ - 0.23V₂ = -1 (2)
substituting equation (1) into (2), we have
0.3V₁ - 0.23(V₁ + 5) = -1
expanding the brackets, we have
0.3V₁ - 0.23V₁ + -0.23 × 5 = -1
0.07V₁ - 1.15 = -1
adding 1.15 to both sides, we have
0.07V₁ = -1 + 1.15
0.07V₁ = 0.15
dividing both sides by 0.07, we have
V₁ = 0.15/0.07
= 2.143 gallons
≅ 2.1 gallons to the nearest tenth
So, we need 2.1 gallons of 30 % hydrogen peroxide to obtain a mixture that is 23 % hydrogen peroxide.

Answers
Answer:
Option C: 11 is the correct answer.
Step-by-step explanation:
Given that:
Length of base of isosceles triangle = b = x
The length of leg of triangle = a = 3x-7
Perimeter of triangle = 63
Perimeter of an isosceles triangle is given by
Perimeter = 2a + b
Putting values in the formula
63 = 2(3x-7) + x
63 = 6x-14+x
63 = 7x-14
63+14=7x-14+14
77=7x
7x=77
Dividing both sides by 7
[tex]\frac{7x}{7}=\frac{77}{7}\\x=11[/tex]
The value of x is 11.
Hence,
Option C: 11 is the correct answer.

In a dance competition, a participant has to score a total of at least 30 points in the first four rounds combined to move on to the fifth and final round. Steward scored 5 points in the first round. He then went on to score additional points in the second, third, and fourth rounds. In each of those rounds, his score was identical. Which inequality best shows the number of points, p, that Steward scored in each of the second, third, and fourth rounds if he earned a place in the finals?
5 + 3p ≥ 30
5 + 3p ≤ 30
5p + 3 ≥ 30
5p + 3 ≤ 30
Answers
Answer:
A) 5+3p ≥ 30
Step-by-step explanation:
The 5+3p has to be greater than 30 to move on to the next round. The student scored 5 points in the first round and since the other 3 rounds he scored the same amount of points, your equation would be 5+3p ≥ 30 :)
If you were to solve this, you would subtract 5 from both sides to find that 3p≥ 25. Divide 25 by 3 to find out that Steward needed to score at least 9 points in each of rounds 2,3, and 4, so a possible solution could be that he earned 5 points in round 1, 9 in round 2, 9 in round 3, and 9 in round 4 for a total of 32, which is enough to qualify for the final round :)

b. What is the difference between the two salary options?

Ripley’s Aquarium charges $29.95 for (a) adults and $13.95 for (c) children. Write an expression to represent admission pricing
Answers
Answer:
T=29.95a + 13.95c
Step-by-step explanation:
For this equation let a=amount of adult tickets, c=amount of children tickets, and T=the total cost. Since each adult ticket costs 29.95 dollars that needs to be multiplied by the number of adult tickets to see how much was spent on adults, the same goes for the price and number of children tickets. Finally, both of those totals need to be added together to see how much is spent overall for all of the guests.

A bag contains 4 red marbles, 8 blue marbles and 2 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that both marbles drawn will be red?
Answers
Answer:
The probability, to the nearest 10th of a percent, that both marbles drawn will be red is 28.5%
Step-by-step explanation:
Number of red marbles = 4
Number of blue marbles = 8
Number of Green marbles = 2
Total number of marbles = 4+8+2 =14
We need to find the probability, to the nearest 10th of a percent, that both marbles drawn will be red?
The formula used will be: [tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Number\:of\;possible\:outcomes}\\[/tex]
In our case, Number of favourable outcomes = 4 (as red marbles are drawn)
Number of possible outcome = 14 (Total number of marbles)
The probability will be:
[tex]Probability=\frac{Number\:of\:favourable\:outcomes}{Number\:of\;possible\:outcomes}\\\\Probability=\frac{4}{14}\\ Probability=0.2857\\[/tex]
Now, calculating nearest 10th of a percent
[tex]Probability = 0.2857*100\\Probability=28.5%[/tex]
So, the probability, to the nearest 10th of a percent, that both marbles drawn will be red is 28.5%

Ahmed works in a factory his normal rate of pay is £12.00 per hour
When ahmed works on sundays he is paid overtime for each hour.The overtime rate of pay is 1 1/4 times his nomal hourly rate. Lat weekend Ahmed worked 9 hours on Saturday and 6 hours on Sunday. Work out how money he earned during that weekend
Answers
Answer:
Ahmed earned £198.00 on that weekend.
Step-by-step explanation:
Given that:
Normal hourly pay = £12.00
Overtime pay = [tex]1\frac{1}{4}[/tex] of normal rate
Overtime pay per hour = [tex]\frac{5}{4}*12[/tex]
Overtime pay per hour = £15.00
Hours worked on Saturday = 9 hours
Amount earned on Saturday = 9*12 = £108.00
Hours worked on Sunday = 6 hours
Amount earned on Sunday = 6*15 = £90.00
Total amount earned on weekend = 108+90 = £198.00
Hence,
Ahmed earned £198.00 on that weekend.
