Identify the x value of the solution to the system of equations.
x – 4y = 1
6x + 4y = 20
Answer:
1x + 4y = 4 ⇒ 6x + 24y = 24
6x - 8y = 0 ⇒ 6x - 8y = 0
32y = 24
32 32
y = 3/4
x + 4(3/4) = 4
x + 3 = 4

Answer:

Goblin Birt can take 15 minutes to count the coins in the bag by himself.
What is unitary mehtod?The unitary method is a process for solving a problem by first finding the value of a unit, and then finding the necessary value by multiplying the single unit value.
How to calculate how long would it take goblin Birt to count the coins in the bag by himself ?In this problem, unitary method is to be applied three times.Here, counting all the coins is considered as the entire work which is considered as 1.According to the problem,
Goblin gryh can count the coins in a bag in 10 minutes.∴ In 10 minutes Goblin gryh can count the coins in the bag.
∴ In 1 minute Goblin gryh can count [tex]\frac{1}{10}[/tex] th part of the coins in the bag.
Again, according to the problem,
Goblin gryh and Goblin Birt both can count all the coins in 6 minutes.∴ In 6 minutes, Goblin gryh and Goblin Birt both can count all the coins in the bag
∴ In 1 minute, Goblin gryh and goblin Birt both can count [tex]\frac{1}{6}[/tex] th part of the coins in the bag.
∴ In 1 minute, Goblin Birt can count [tex](\frac{1}{6} - \frac{1}{10})[/tex] th part of the coins in the bag.
= [tex]\frac{5-3}{30} = \frac{2}{30} = \frac{1}{15}[/tex] th part of the coins.
∴ We can say,
Goblin Birt can count [tex]\frac{1}{15}[/tex] th part of the coins in the bag in 1 minute.
∴ Goblin Birt himself can count all the coins in the bag in 15 minutes.

Give an example of a binomial of degree 27
Answer:
x27 + y.
Step-by-step explanation:
Binomial means having 2 terms so binomial of degree 27 is x^27 + y type.
For example,
x^27+y+2
If there are 2 degree terms of x, degree of the one having highest degree is taken.
For example,
In x^27+x^10
As highest degree is 27, this is a binomial of degree 27.

Students in a school were asked to collect old bottles as part of a recycling drive. Some of the data recorded at the drive is shown in the histogram below:
Which information is not provided in the histogram?
The total number of students who collected bottles
The number of students who collected exactly 9 bottles
The number of students who collected 3 or fewer bottles
The total number of students who collected 7 or fewer bottles
Answer:
The number of students who collected exactly 9 bottles.
Step-by-step explanation:
The given histogram shows the number of students who participated in the recyling drive & their old bottle waste collection.
We can find out the total number of students who participated just by looking at the histogram (students = 10), the number of students who colected bottles below 7 or 3 bottles etc.
But since the number of bottles is given in the form of grouped data, one cannot infer the exact number of bottles collected by students.
Hence, out of the given statements, 'The number of students who collected exactly 9 bottles' is the incorrect one.

Explanation:
There are a few ways to measure the period. One way is to measure the horizontal distance from peak to peak.
The left peak occurs at x = 1
The right peak occurs at x = 17
This is a horizontal distance of 17-1 = 16 units.
Therefore, the period is 16. The curve repeats itself every 16 units.

Based on meteorological records, the probability that it will snow in a certain town on January 1st is 0.315. Find the probability that in a given year it will not snow on January 1st in that tow
The probability that in a given year it will not snow on January 1st will be P = 0.915.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Since the total probability is always equal to 1 if the probability of happening of an event is given then the probability of not happening of an event will be determined by subtracting it from one.
The probability of not any snowfall will be calculated as:-
P = 1 - 0.315
P = 0.615
Therefore the probability that in a given year it will not snow on January 1st will be P = 0.915.

Remark
If you take one radius whose length is r and start it at (0,0) on one end and (r,0) at the other, and sweep it around so the (r,0) hits every point on the circumference of the circle, the radius will go through 360°.
You have only gone through 120°. That's no problem. All you have to do now is add a fraction that adjusts for the 120°.
Formula
Arc length = fraction * 2*pi * r
2*pi * r is the circumference
Arc Length = 2* (120/360) * pi * r
Givens
r = 13
pi = 3.14
Solution
Arc Length = (120/360) * 2 * pi * 13
Arc Length = 27.21

Arc Length = 27.21

In box 1, the reason that justifies the statement, m∠BAD = m∠BAC + m∠CAD, is: angle addition postulate.
What is the Angle Addition Postulate?The angle addition postulate states that the measure of a larger angle equals the sum of smaller angles that make up the larger angle.
∠BAD comprises of ∠BAC and ∠CAD.
