Solve the following equation - 2(x-8)=18-3(5x+6)
Answer:
-2(x-8)=18-3(5x+6)
-2x+16=18-15x-18
-2x+15x=18-18+16
13x=16
X=16/13
Answer:
[tex]x=-\frac{16}{13}[/tex]
Step-by-step explanation:
[tex]-2(x-8)=18-3(5x+6)[/tex]
Start by distributing [tex]-2[/tex] into [tex](x-8)[/tex], and [tex]-3[/tex] into [tex](5x+6)[/tex]:
[tex]-2x+16=18-15x-18[/tex]
Combine like terms:
[tex]-2x+16=-15x[/tex]
Subtract [tex]16[/tex] from both sides of the equation:
[tex]-2x=-15x-16[/tex]
Add [tex]15x[/tex] to both sides of the equation:
[tex]-13x=16[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-13[/tex]:
[tex]x=-\frac{16}{13}[/tex]
how do you convert 12 over 100 to a percentage
Answer:
12%
Step-by-step explanation:
A percent is any fraction with 100 as a denominator. So [tex]\frac{12}{100}[/tex] is the same as 12% and 4 over 100 is the same as 4%
Here's an easy was to remember, there are 100 pennies to make a dollar that like per-CENT it's out of 100.
Hope that helps and have a great day!
Answer:
12%
Step-by-step explanation:
your question isn't giving me an option to answer but do 12 divided by 100 and you get a decimal, then multiply it by 100 which will give you the percentage. In this case is would be 12%

8. Three groups of 10 kids. The average weight of a kid in each
group is 35 kilograms. One more kid joined each group.
i) The average weight of a kid in the first group is still 35
kilograms.
The average weight of a kid in the second group is now
36 kilograms.
iii) The average weight of a kid in the third group is now
34 kilograms.
Compute the weight of the new kid in each group.
25
Answer: 385
Step-by-step explanation:
Mean the three groups of 10 kids=35
Total weight of 3 groups (10x35)=350
Mean weight of 3 groups and one boy ( 35 + 350)=385

1. Reasoning from a sample to a population.
2. Successive observations of a system or phenomenon do not produce exactly the same result.
3. An observation that differs considerably from the main body of the data.
4. The entire collection of objects or outcomes about which data are collected.
5. A subset of the population containing the observed objects or outcomes and the resulting data from these objects or outcomes.
A. Population
B. Sample
C. Statistical Inference
D. Variability
E. Outlier
Answer:
1. Statistical Inference
2. Variability.
3. Outlier.
4. Population.
5. Sample.
Step-by-step explanation:
1. Statistical Inference: Reasoning from a sample to a population. For example, the average common entrance score of all examinees (population l) in New York city or a business that collects data from a random sample of 100 consumers and recorded whether they are male or female.
2. Variability: Successive observations of a system or phenomenon do not produce exactly the same result. For instance, the distribution having the same value of mean can have varying variability.
3. Outlier: An observation that differs considerably from the main body of the data. For example, in the following scores 1, 2, 3, 4, 50, 5, 60; both 50 & 60 is an outlier.
4. Population: The entire collection of objects or outcomes about which data are collected. For example, the number of new born babies in a hospital, the total number of football players in a soccer league.
5. Sample: A subset of the population containing the observed objects or outcomes and the resulting data from these objects or outcomes. For example, the average height of girls in a class having a population of 10 boys and 20 girls.
Three roots of the polynomial equation x^4 - 4x^3 - 2x^2 + 12x + 9 = 0 are 3, -1, and -1. Explain why the forth root must be a real number. Find the forth root.
Hello,
This polynomial function has maximum 4 roots as the degree is 4
and their coefficients are all reals so if one root is a complex number, its conjugate is a root too.
As we know already 3 roots and none of them is a complex number, the fourth one is a real number
And their product is 9 = 3 * 1 * (-1) * (-3) as
[tex](x-x_1)(x-x_2)(x-x_3)(x-x_4)=x^4+...+x_1x_2x_3x_4[/tex]
(The constant term is 9, the product of the roots)
so the last root is -3

A wave travels 1/3 mile in 1/20 hour. At this rate, how far will the wave travel in 1 hour?
A wave will travel 6.7 mile in 1 hour.
Given that,
A wave travels 1/3 mile in 1/20 hour.
How to calculate the distance in given time?
To calculate the value of distance at time is given as,
Distance = Speed X Time
To given condition wave travels 1/3 mile in 1/20 hour,
We calculate,
⇒ [tex]\frac{1}{3}[/tex] ÷ [tex]\frac{1}{20}[/tex]
Divide a fraction by multiplying its reciprocal,
⇒ [tex]\frac{20}{3}[/tex]
⇒ [tex]6.66667[/tex]
⇒[tex]6.7[/tex] mile
So a wave will travel 6.7 mile in 1 hour.

Answer:
28cm
Step-by-step explanation:
ive done this question before
Answer:
28 cm
Step-by-step explanation:
This is the answer because:
Perimeter = L + W + L + W
Area = L x W
1) Since the shape is a square, there has to be two of the same factors that multiply.
_ x _ = 49
2) We know 7 x 7 = 49, therefore, w just have to add 7 + 7 + 7 + 7 which equals 28 cm
Therefore, the answer is 28 cm

How many possible solutions are ther to a linear equation in one variable
Answer:
Step-by-step explanation:
Every linear equation that is a conditional equation has one solution. However, not every linear equation in one variable has a single solution. There are two other cases: no solution and the solution set of all real numbers. resulting value on the right side will always be one greater than the value on the left side.

the sum of the first 10 terms of an AP is four times the sum of the first 5 terms then the ratio of the first term to the common difference is
Answer:
The ratio of the first term to the common difference is 1 : 2
Step-by-step explanation:
The rule of the sum of the AP is
[tex]S_{n}=\frac{n}{2}[2a+(n-1)d][/tex] , where
a is the first number
d is the common difference
n is the position of the number
∵ [tex]S_{10}[/tex] = 4 × [tex]S_{5}[/tex] ⇒ (1)
→ Find [tex]S_{10}[/tex] and [tex]S_{5}[/tex]
∵ In [tex]S_{10}[/tex] n = 10
∴ [tex]S_{10}=\frac{10}{2}[2a+(10-1)d][/tex]
∴ [tex]S_{10}=5[2a+9d][/tex]
∴ [tex]S_{10}[/tex] = 10a + 45d ⇒ (2)
∵ In [tex]S_{5}[/tex] n = 5
∴ [tex]S_{5}=\frac{5}{2}[2a+(5-1)d][/tex]
∴ [tex]S_{5}=2.5[2a+4d][/tex]
∴ [tex]S_{5}[/tex] = 5a + 10d ⇒ (3)
→ Substitute (2) and (3) in (1)
∵ 10a + 45d = 4[5a + 10d]
∴ 10a +45d = 20a + 40d
→ Subtract 40d from both sides
∴ 10a + 45d - 40d = 20a + 40d - 40d
∴ 10a + 5d = 20a
→ Subtract 10a from both sides
∴ 10a - 10a + 5d = 20a - 10a
∴ 5d = 10a
→ Divide both sides by 5
∴ d = 2a
→ That means d is twice a or a is half d
∴ a : d = 1 : 2
The ratio of the first term to the common difference is 1 : 2
