Answer:
a=-2
Step-by-step explanation:
3a−6=−12
Step 1: Add 6 to both sides.
3a−6+6=−12+6
3a=−6
Step 2: Divide both sides by 3.
3a/ 3 = −6/ 3
a=−2
What is the purpose of scientific notation? How is scientific notation represented? Explain.
plz help
Answer:
Step-by-step explanation: The purpose of scientific notation is to make the numbers and quantities used easier to comprehend, to read and to write.
Express both numbers with the same power of ten.
Add the base numbers.
Bring the power of ten down to represent the new power of ten for the sum.
Simplify so that the base number is between 1 and 10.

Answer : 1/2 gallon
Explanation:
There were a total of 5 gallons collected, as the question states.
There are 3 x's above 1/4, 2 x's above 3/8, 4 x's above 5/8 and 1 x above 1. This is a total of
3+2+4+1 = 10 x's. This means there were 10 trees.
If 5 gallons is evenly distributed among 10 trees, this would give us the ratio 5/10, which simplifies to 1/2 gallon per tree.

Answer:
arc CD = 160°
Step-by-step explanation:
The measures of the arcs on the circle = 360° , then
arc CD = 360 - AC - AD = 360 - 3x - 7x = 360 - 10x
--------------------------------------------------------------------------
The measure of the secant- tangent angle ABC is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (7x - 3x) = 40 ( multiply both sides by 2 to clear the fraction )
7x - 3x = 80
4x = 80 ( divide both sides by 4 )
x = 20
Then
CD = 360 - 10x = 360 - 10(20) = 360 - 200 = 160°

Which table represents a linear equation
I need the answer fast please !
Answer:
30
Step-by-step explanation:
Angles on a straight line are equal to 180°
180°-120°= 60°
Sum of Co interior angles are equal to 180°
180°-60° =120°
90°+60°+ x = 180°
((180° - 90° - 60°= 30°))

Which of the following statements about the graph of y = 3x - 5 are true? Select all that apply.
A.
The y-intercept is -5.
B. The x-intercept is 3.
C. (2, 1) is a point on the graph.
D. As the x-values increase, the y-values also increase.
The y-intercept is -5 and as the x-values increase, the y-values also increase in this graph of the line. which is the correct answer would be options (A) and (D).
What is a graph?
A graph can be defined as a pictorial representation or a diagram that represents data or values.
What is the equation of a line?
The general equation of a line is y = mx + c
where m is the slope of the line and c is the intercept.
A linear equation is defined as an equation in which the highest power of the variable is always one.
We have been given that function of the line as
y = 3x - 5
We need to determine the y-intercept.
The y-intercept is at x = 0, y = -5
And the x-intercept is at y = 0, x = 5/3
Here In this graph of the given function as the x-values increase, the y-values also increase.
Therefore, the correct answer would be options (A) and (D).

Doug's teacher told him that standardized score (s-score) for his mathematics exam, as compared to the exam scores of other students in the course, is 1.20.
Full question:
Doug's teacher told him that the standardized score (z-score) for his mathematics exam, as compared to the exam scores of other students in the course, is 1.20. Which of the following is the best interpretation of this standardized score?
Doug's test score is 120.
Doug's test score is 1.20 times the average test score of students in the course.
Doug's test score is 1.20 above the average test score of students in the course.
Doug's test score is 1.20 standard deviations above the average test score of students in the course.
None of the above gives the correct interpretation.
Answer:
Doug's test score is 1.20 standard deviations above the average test score of students in the course.
Explanation:
Z scores are also known as standardized scores or normal scores or standardized variables. Z scores are used to standardize raw data in order to give them a uniformity or standard that allows for easier comparison of data values. For us to calculate a z-score as was done in Doug's test score, we simply subtract the mean from the raw data score and we divide the answer by the standard deviation.
