What is Linear Equation in 1 variable?
The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution
Given data ,
A )
19 + b + 12b – 8 – 5b = 2b – 7 + 3b + 3b – 4
On Simplifying , we get
8b + 11 = 8b - 11
Hence , the option has no solution
B )
4b – 9b – 13 – 6 + 16b = 1 – 8 + 6b + 5b – 12
On Simplifying , we get
11b - 19 = 11b - 19
Adding 19 on both sides , we get
11b = 11b
Divide by 11 on both sides , we get
b = b
Hence , the option has a solution
C )
7 + 7b – 2 – 15b + b = 4b – 5 – 11b + 2 + 10
On Simplifying , we get
- 7b + 5 = - 7b + 7
Hence , the option has no solution
D )
10b + 8b + 9 – 18b + 3 = 5 + 6b – 2b – 12 + 7
On Simplifying , we get
0 + 12 = 4b + 0
4b = 12
Divide by 4 on both sides , we get
b = 3
Hence , the option has a solution
E )
9 – 19b – 9 – 2b + 7b = 4b + 3 + 14 – 4b – 17
On Simplifying , we get
0 - 14b = 0
b = 0
Hence , the option has a solution
F )
8b – 10 + b + 3b + 2 = 7 + 2b + 10b – 18 – 3
On Simplifying , we get
12b - 8 = 12b - 12
Hence , the option has no solution
Therefore , the three equations that have no solutions are A ,C and F

What is the value of 6 in the number 45.026
Spin a spinner numbered 1-8 two times, land on two the first time and
land on a factor of 8 the second time
Answer:
Required probability = 1/16
Step-by-step explanation:
When we spin a spinner numbered 1-8, we find that each spin is independent of the other.
HEnce probability for getting any number from 1 to 8 will be equal to 1/8 and remain the same for each spin.
So Probability on two for the first time and factor of 8 on the second time
=Prob (landing on 2)*Prob (landing on any factor of 8)
P(landing on 2) = 1/8
Factors of 8 are 1,2,4,8
Prob (landing on factor of 8) = 4/8
Hence required prob = 1/8(4/8) =1/16
What is the approximate solution of this system of equations?
y = x2 + 3x + 3
y = x2 + x + 2
(-0.5, 0.2)
(-0.5, 1.7)
(-0.1, 1.2)
(0.2, 1.5)
Answer:
(B)
Step-by-step explanation:
The given system of equations are:
[tex]y=x^2+3x+3[/tex] (1)
and [tex]y=x^2+x+2[/tex] (2)
Subtracting equation (2) from (1), we get
[tex]0=2x+1[/tex]
⇒[tex]2x=-1[/tex]
⇒[tex]x={\frac{-1}{2}}[/tex]
⇒[tex]x=-0.5[/tex]
Now, substituting the value of x=-0.5 in equation (2), we get
[tex]y=0.25-0.5+2[/tex]
⇒[tex]y=1.7[/tex]
Thus, the values of x and y are -0.5 and 1.7.
Therefore, the approximate solution of the given system of the equation is (-0.5, 1.7).
Hence, option (B) is correct.
the points (10, 6) and (7, u) fall on a line with a slope of -4/3. what is the value of u?
In the number 7,889 which contains digits where one digit is ten times the value as the other digit?
How do u find the mean? I've never done this before the subject is try check and revise
Answer,
The mean is the average of the numbers. It's quite simple to find the mean. All you do is, add all the numbers togter & divide by how many numbers there are. In simpler words, it is the sum divided by the count.
For example,
The mean of the numbers is, 50
Explanation,
20 + 30 + 40 + 50 + 60 + 70 + 80 = 380
Then we divide 350 by how many numbers there are, 7. Then we get 50.

Kevin works as a salesperson at a site that specializes in custom made computers. He earns a base pay of 325$ per week and a commission on his sales. If Kevin earned a total of $1125 last week, how much of it was commission?
Answer:
$800
Step-by-step explanation:
Kevin works as a sales person at a site that specialize in custom made computers.
Kevin earns a base pay per week = $325
and a commission on his sales.
Kevin earned last week a total of = $1,125
So his commission = Total pay - his base pay
= 1,125 - 325
= $800.00
His commission was $800.
Two congruent triangles fit together to form a parallelogram with a base of 14 inches and a height of 10 inches. What is the area of each triangle?
Final answer:
The area of each triangle is 140 square inches.
Explanation:
The area of a triangle is given by the formula A = ½ × base × height.
In this case, the base of the parallelogram is 14 inches and the height is 10 inches.
Since two congruent triangles form the parallelogram, we can consider one of the triangles.
Let's call the base of the triangle 'b' and the height 'h'.
We have the equation A = ½ × b × h = 14 × 10 = 140 square inches.
Therefore, the area of each triangle is 140 square inches.

Ian is going to water his plants is it reasonable to say he will fill the watering can with 3 liters of water explain
Final answer:
It is reasonable for Ian to fill a watering can with 3 liters of water for watering plants, as it falls within the typical range required by houseplants and should suffice for watering multiple indoor plants or a small garden.
Explanation:
To determine if it is reasonable for Ian to fill a watering can with 3 liters of water to water his plants, we should consider the capacity of common watering cans and the typical water requirements for houseplants. For example, a standard watering can might hold anywhere from 1 to 10 liters of water, and most indoor plants generally require between 0.25 and 1 liter of water per week, depending on their size and the environmental conditions.
If Ian has several plants or a few large plants, 3 liters of water might be a perfectly reasonable amount for him to use. Without knowing the exact number and size of the plants, it is difficult to provide a precise answer, but in general, 3 liters is within a normal range for watering multiple houseplants.
For a substantial garden or larger outdoor plants, 3 liters might even be on the lower end, and multiple trips to the tap may be necessary. Thus, it is indeed reasonable to say that Ian will fill the watering can with 3 liters of water for watering plants.

What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given, Miki, a resident of Kyoto, earns an annual salary of ¥6,760,950.
Since,
the Japanese government levies a 29.12% income tax on Miki’s tax bracket
Thus,
tax she pays = 6,760,950 *29.12%
tax she pays = 6,760,950 *29.12/100
tax she pays = 1,968,788.64¥
remaining income to take home = total income - tax
remaining income to take home = 6,760,950 - 1,968,788.64
remaining income to take home = 4792161.36¥
Therefore, her yearly take-home pay, to the nearest whole yen is 4792161¥

If 16-7w=w+14-6w16−7w=w+14−6w16, minus, 7, w, equals, w, plus, 14, minus, 6, w, what is the value of w-1w−1w, minus, 1?
Answer:
Value of w = 1
w - 1 = 1 - 1 = 0
Explanation:
We have 16 - 7w = w + 14 - 6w
Firstly, we will find the value of w.
In order to find the value of w, we will solve the linear equation for w.
Now combine like terms
16 - 14 = w - 6w + 7w
2 = 2w
2w = 2
w = [tex] \frac{2}{2} [/tex]
w = 1
Now we will find the value of w - 1
Plug the value of w = 1 into w - 1
1 - 1
= 0
So, final answer is 0

Polynomials can be classified based on degree as linear, quadratic, cubic, fourth degree.
Let f(x) represent the function with zeros 4, 8i , and 4i. Hence:
x = -4; 8i; x = 4i
x + 4 = 0; x - 8i = 0; x - 4i = 0
f(x) = (x + 4)(x - 8i)(x - 4i)
