8c+5=4c-11

Answers

Answer 1
Answer:
You said that                               8c + 5  =  4c - 11

Subtract  4c  from each side:      4c + 5  =       - 11

Subtract  5  from each side:        4c        =       - 16

Divide each side by  4 :                c        =        - 4
Answer 2
Answer: First you combine like terms: 8c-4c
Your equation now: 4c-5=-11
Next you will add 5 to both sides
Your equation now: 4c = -16
Then you will divided 4 from both side
Your equation now: c=-4
Hope this helps!

Add the fractions and simplify the answer: 1/2 + 2/3

Answers

The simplification of the fraction would be; 7/6.

What is a fraction?

A fraction represents a part of a number or any number of equal parts. There is a fraction, containing numerator(upper value) and denominator(lower value).

Therefore, first convert the denominator (bottom n umber) to the same number.

1/2 and 2/3 then the numbers are 2 and 3

the least common multiple is 6

To convert is multiply each by bottom number of the other over the other;

1/2 +2/3

1/2 x 3/3 + 2/3 x 2/2

3/6 + 4/6

(7)/6

7/6

Hence, the simplification of the fraction would be; 7/6.

please help :) Geography doesn’t simply begin and end with maps showing the location of all the countries of the world. In fact, such maps don’t necessarily tell us much. No—geography poses fascinating questions about who we are and how we got to be that way, and then provides clues to the answers. ~Kenneth Davis The speaker in the passage above is stating that a. maps are not helpful to historians. b. human geography is more important than physical geography. c. historians want to know where people settled. d. physical features and locations tell historians about the ways people lived.

Step-by-step explanation:

find the equation of the line passing through the point (-4,1) and the perpendicular to the line y=1/3x+4

Answers

Answer:

The answer is

y = - 3x - 11

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

From the question

y = (1)/(3) x + 4

Comparing it with the general equation above

Slope / m = 1/3

Since the lines are perpendicular to each other the slope of the other line is the negative inverse of the original line

That's

Slope of perpendicular line = - 3

Equation of the line using point (-4 , 1) and slope - 3 is

y - 1 = - 3(x + 4) \n y - 1 = - 3x - 12 \n y = - 3x - 12 + 1

We have the final answer as

y = - 3x - 11

Priya is playing a game where she earns online badges for scoring higher than the mean score on a level. After the tenth level, she scores 3,540 points, which is 2 standard deviations above the mean score of 3,110 points.What is the standard deviation of scores for the tenth level?

a.)215
b.)311
c.)354
d.)430

Answers

If score of 3,540 points is 2 standard deviations above the mean score of 3,110, then:
3,110 + 2 s= 3,540
2 s = 3,540 - 3,110 = 430
s = 430 : 2
s = 215
Answer: A) The standard deviation is 215. 

The standard deviation of scores for the tenthlevel is 215 and is denoted as option A.

What is Standard deviation?

This is defined as the measure of the amount of variation or dispersion of a set of values.

We were told that score of 3,540 points is 2 standard deviations above the mean score of 3,110 therefore,

3,110 + 2 s= 3,540

2 s = 3,540 - 3,110

2s = 430

s = 430/2

s = 215
