I’m not sure though.
You get this answer because you need to find out how many km per cm, so you divide 12 by 8. This will get u the answer of how many km per cm. Then you multiply by six cm because this is the length on the map between home and her job. This will get you the answer 4.

Jada has 12 library books checked out and Han has LaTeX: \frac{1}{3}1 3 less than that. How many books does Han have checked out?
Answers
Answer:
8
Step-by-step explanation:
The questions is difficult to read but if it means "Jada has 12 library books checked out and Han has 1/3 less than that" Han would have 8 because 12/3 is 4. 12-4 is 8. This would only be correct if that is what the problem means. Sorry. I'm not sure what "LaTeX: \frac{1}{3}1 3" means.
HELPPP! ALMOST DUE! Clara estimated that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s actual height is 4 feet, 2 inches. What was the percent error for Clare’s estiamate? PLZ HELP!!!
Answers
Answer:
Her error in terms of inches was 2 inches while her percent error was 4.166%
Step-by-step explanation:
From the given data Claire estimated her brother to be shorter than he actually was. She estimated his height to be 4 feet while it was actually 4 feet 2 inches.
We convert the feet into inches because 12 inches are equal to a feet.
4 feet = 4 × 12 inches = 48 inches
4 feet 2 inches = (4 × 12 inches) + 2 inches = 48 + 2 = 50 inches
Error in terms of inches = 50 inches - 48 inches = 2 inches.
Step 2 ; Her percent error is given by dividing the difference in values by the actual value multiplied by 100.
% error = (difference in values / actual value) × 100
Claire's % error = (50 - 48)/ 48 × 100 = 2/48 × 100 = 0.04166 × 100 = 4.166%
Answer:
A 4% difference
Step-by-step explanation:
Convert 4 feet 2 into 4.16666666
4/4.16666666= 0.96 or 96%
4 feet was 96% of 4 feet 2 in
100 - 96= 4%
And this shows that there was a 4% error.
Hope it helped!

Which of these graphs is the solution set for the equation y = -3x - 2?
Answers
The negative before the 3 means the slope is going down
The 3 means it goes 3 down every time it goes right one, the number before the x is the slope and slope is rise over run, 3 = 3/1 so it would normally mean it goes up 3 every time it goes right one but because the 3 is negative it means the line goes down
The negative two at the end moves the line down two, if it were plus two the line would go up two, the number in this spot is what determines the vertical translation
Put it all together and you get the line has goes down 3 every time it goes right one and crosses the y axis at -2

Which of the following is another way to express the equation 13 = -3 + z?
A. 13 = - z - 3
B. 13 = z - 3
C. 13 = - z + 3
D. 13 = z + 3
Answers
The other representation of the given equation 13 = -3 + z will be 13 = z - 3 thus option (C) is correct.
What is the equation?More than one variable may be present inside a linear equation.
An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
As per the given equation,
13 = -3 + z
Since, A + B = B + A
Thus, -3 + z can be written as z - 3
So, 13 = z - 3
Hence "The other representation of the given equation 13 = -3 + z will be 13 = z - 3".
