Step-by-step explanation:
9x - 8 = 6x + 4
3x - 8 = 4
3x = 12
x = 4
Answer:
9x - 6x = 4 + 8
3x = 12
x = 12÷ 3
x = 4
Step-by-step explanation:
restamos las variables, verificamos que 9x es mayor que 6x por lo cual lo trasladamos al lado del 9x. Lo cual sería 9x menos 6x , por el lado del menos ocho y el cuatro, al menos ocho lo volvemos positivo lo cual da 4 más 8. y así
9x - 6x = 4 + 8
3x = 12
x = 12÷ 3
x = 4

Answer for x.
1. 3x - 10 = -21
2. -22 - 4x = 12
Answer:
3x - 10 = -21
add 10 on both side
3x-10+10=-21+10
3x=-11
divide both side by 3
3x/3=-11/3
x=-11/3
Step-by-step explanation:
2. -22 - 4x = 12
add 22 on both side
-22+22-4x=12+22
-4x=36
divide both side by -4
-4x/-4=36/-4

I need help fast! The measures of the angles of a triangle are shown in the figure below. Solve for x.
Using the same triangle as above, provide a value for the measure of angle A. Use this value, along with the values you have provided in question 3, to calculate the length of side c and the measure of angle B. The value of A should be between 20 and 70 and cannot be the same as angle C.
Answer:
Step-by-step explanation:
Since the triangle is a right triangle, we know angle B is 90
Then, we know A and C have to make 90 to
so if A has to be between 20 and 70, we can pick 21
as long as A and C make 90, if A is 21, then C is 69
since 21 + 69 = 90
Since it's a right triangle, we can use pythagoran theorem to find c
a² + b² = c²
c = [tex]\sqrt{a^{2} + b^{2} }[/tex]
then you put in the numbers from question 3 (you didn't say what numbers those have to be) and you can find out whats c

A bag contains 100 marbles which are red, green, and blue. Suppose a student randomly selects a marble without looking, records the color, and then places the marble back in the bag. The student has recorded 7 red marbles, 2 green marbles and 11 blue marbles. Predict how many green marbles are in the bag.
Answer:
80
Step-by-step explanation:
If the bag has 100 marbles and 7+2+11=20 then you subtract what you got adding the quantities you already know from the total, and you have your answer :D
The expression 52,260 + 2Sh represents the annual salary for a graphic artist. This includes the base salary and $25 per hour for work on special projects, where h = number of hours. If the artist spends 160 hours on special projects throughout the year, how much in total will the artist earn? $55,260 548, 260 $8,365,000 $56, 260
Answer:
56,260
Step-by-step explanation:
plug in h = 160 into the equation:
52,260 + 25h --> 52,260 + 25 * 160 = 52,260 + 4000 = 56,260.
The artist will earn in total $56, 260.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
The given expression that represents the annual salary for a graphic artist is,
52,260 + 25h
where, h = number of hours
Now If the artist spends 160 hours on special projects throughout the year, put h = 160 in the given expression,
52,260 + 25h = 52,260 + 25*160
or, 52,260 + 25h = 52,260 + 4000
or, 52,260 + 25h = 56,260
which is the required amount an artist will earn in an year.
Thus, the artist will earn in total $56, 260.
The correct expression in the question is,
52,260 + 25h

A researcher reports that 80% of high school seniors would pass a driving test, but only 45% of high school freshmen would pass the same driving test. Assume that the researcher’s claim is true. Suppose a driving test is given to a random sample of 90 high school seniors and a separate random sample of 85 high school freshmen. Let and be the sample proportions of seniors and freshmen, respectively, who pass the test. What are the shape and mean of the sampling distribution of ? skewed left with mean –0.35 skewed right with mean 0.625 exactly Normal with mean 0.35 approximately Normal with mean 0.35 approximately Normal with mean 0.625
Answer:
approximately Normal with mean 0.35
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
A researcher reports that 80% of high school seniors would pass a driving test, but only 45% of high school freshmen would pass the same driving test.
This means that [tex]p_1 = 0.8, p_2 = 0.45[/tex]
Subtraction of Variable 1 by Variable 2:
By the Central Limit Theorem, the shape will be approximately normal.
The mean is the subtraction of the means of each proportion. So
[tex]p = p_1 - p_2 = 0.8 - 0.45 = 0.35[/tex]
So the correct answer is given by:
approximately Normal with mean 0.35

The total profit function, P(x), for a company producing x thousand units is given by P(x)=−2x²+38x−120. Find the values of x for which the company makes a profit. [Hint: The company makes a profit when P(x)>0.] Explain and justify your answer.
Answer:
4 < x < 15.
Step-by-step explanation:
Solve -2x^2 + 38x -120 = 0 This gives x = 4 and x = 15. So the company makes a profit when the range of x is greater than 4 and less than 15. The graph of function is a flipped U which pass through x axis at 4 and x = 15. Above the x-axis is the area of profit.

Triangle Inequalities help please
Answer:
No, you can't
Step-by-step explanation:
Given
[tex]Side\ 1 =4[/tex]
[tex]Side\ 2 =9[/tex]
Required
Is a perimeter of 26 possible?
First, calculate the possible side 3
[tex]Side\ 3 = Perimeter - Side\ 1 - Side\ 2[/tex]
[tex]Side\ 3 = 26 - 4 - 9[/tex]
[tex]Side\ 3 = 13[/tex]
Triangle inequalities states that:
Sum of two sides > the third side
So:
[tex]4 + 9 > 13[/tex] --- False
[tex]13 + 9 > 4[/tex] --- True
[tex]4 + 13>9[/tex] ---- True
Since one of the inequalities is false, then a perimeter of 16 is not possible
