Answer:
The number of green pens sold are 96 green pens
Step-by-step explanation:
The given parameters for the packs of pens sold by the shop are;
The number of pens in each pack of black pens = 2 pens
The number of pens in each pack of red pens = 5 pens
The number of pens in each pack of green pens = 6 pens
The ratio of number of packs of pens sold Black : Red : Green = 7 : 3 : 4
The total number of pens sold = 212
Let 'x' represent the number of packs of pens sold
Therefore, the fraction of the packs the pens sold that are black pens = 7/(7 + 3 + 4) = 7/14 = 1/2
∴ 1/2 of the number of packs of pen sold = packs black pens = x/2
The fraction of the packs the pens sold that are red pens = 3/14
∴ 3/14 of the number of packs of pen sold = packs of red pens = 3·x/14
Similarly, we have;
The fraction of the packs the pens sold that are green pens = 4/14 = 2/7
∴ 2/7 of the number of packs of pen sold = packs of green pens = 2·x/7
Therefore, we have;
x/2 × 2 + 3·x/14 × 5 + 2·x/7 × 6 = 212
Where;
x/2 × 2 = The number of black pens sold
3·x/14 × 5 = The number of red pens sold
2·x/7 × 6 = The number of green pens sold
∴ 53·x/14 = 212
x = 212 × 14/53 = 56
∴ The number of packs of pens sold = x = 56 packs
The number of green pens sold = 2·x/7 × 6 = 2 × 56/7 × 6 = 96
The number of green pens sold = 96 pens.

Answer:
28 in
Step-by-step explanation:
Given is an isosceles triangle.
In an isosceles triangle, measure of the sides opposite to the equal angles are equal.
Therefore,
3x + 2 = x + 6
3x - x = 6 - 2
2x = 4
x = 4/2
x = 2 in
x + 6 = 2 + 6 = 8
Perimeter of the triangle
= 8 + 8 + 12
= 28 in

Answer:
c = 0.01 | Hope I helped :')
Steps to answer:
1. Divide both sides by -10.
-0.1/-10=c
2. Simplify -0.1/-10 to 0.01.
0.01=c
3 Switch sides.
c=0.01

Checking your answer:
−0.1=−10c
1 Let c=0.01.
−0.1=−10×0.01
2 Simplify 10×0.01 to 0.1.

36 - 7p = -7 ( p - 5)
a) No Solution
b) One Solution
c) Infinite Solutions
Answer:
a) No Solution
Step-by-step explanation:
36 - 7p = -7(p - 5)
36 - 7p = -7p + 35
1 - 7p = -7p
1 = 0p
so a) No Solution
Answer:
[tex]36 - 7p = - 7(p - 5) \\ 36 - 7p = - 7p - 7 \times - 5 \\36 - 7p = - 7p + 35 \\ p \: terms \: togather \\ - 7p + 7p = 35 - 36 \\ 0p = - 1 \\ here \: we \: \: have \: 0p \\ so \: no \: solution \\ option(a) \\ thank \: you[/tex]

Cisco is building a container for his plants. It is made out of a cube and two cylinders. He plans to paint each surface but cuts off the top of the two cylinders. He also wants to reinforce all the edges before putting it together. Which one is greater, the number of surfaces he has to paint, or the number of edges he has to reinforce
Answer:
Neither
Step-by-step explanation:
In the context, Cisco is building container for the plant which is made up of one cube and two numbers of cylinders. He wants to paint each of the surfaces of the figure but he cuts off the top of two cylinders. Thus neither of the surfaces are greater as Cisco has two cylinders or surfaces and a cube or a point that he cuts the two cylinders and now that he has four surfaces and a cube that has four points.

Answer:
20%
Step-by-step explanation:
Mr. And Mrs. Jenkins wanted to make a down payment of $25,000 on a house. If the house costs $125,000, what percent is this?
The Percentage of the down payment is given as:
Down payment/Cost of the house × 100
Down payment = $25,000
Cost of the house = $125,000
$25,000/$125,000 × 100
= 20%
The percentage is 20%

Answer:
explaination
Step-by-step explanation:
# carry on learning
The solution is, A. y = 5x, the equation represents the relationship between x and y.
What is equation?An equation can be stated as a mathematical statement that is made up of two expressions connected by an equal sign. In its normal form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
Direct proportion equation:
y = kx, where k is the coefficient of proportionality
We have:
x = 3 and y = 15
Using the equation to find the value of k:
15 = 3k
k = 15/3
k = 5
The equation of the line:
y = 5x
Correct choice is A
Hence, The solution is, A. y = 5x, the equation represents the relationship between x and y.

Sandra wrote the sequence shown:
7, 14, 25, 40, 59
Complete each of the 2 activities for this Task.
Activity 1 of 2
What explicit expression can be used to find the nth term of this sequence?
Answer:
2n^2 + n + 4.
Step-by-step explanation:
7, 14, 25, 40, 59
The differences are 7, 11, 15, 19 which is arithmetic sequence so the given sequence is quadratic.
Compile a table:
n 1 2 3 4 5
term 7 14 25 40 59
Diff: 7 11 15 19
Diff: 4 4 4 - this indicates that first part is 2n^2.
2n^2 2 8 18 32 50
term-2n^2 5 6 7 8 9
- the nth term for the last sequence is 5+ (n - 1)d =
= 5 + (n - 1)* 1
= n + 4.
So nth term for the original sequence is 2n^2 + n + 4.
The slope of a line is -1/5, and the y-intercept is 5. What is the equation of the line written in general form?
x - 5y - 5 = 0
x - 5y - 25 = 0
x + 5y - 25 = 0
Answer:
x + 5y - 25 = 0
Step-by-step explanation:
Equation of line in slope intercept form is given as:
[tex]y = mx + b \\ \\ plug \: m = - \frac{1}{5} \: \: and \: \: b = 5 \\ \\ y = - \frac{1}{5} x + 5 \\ \\ 5y = - x + 25 \\ \\ x + 5y - 25 = 0[/tex]
Answer:
x + 5y - 25 = 0
