Answer: its different because when you add a negative sign to an answer it is valued less then a answer without the negative sign
Answer:
You use the division property of inequality to isolate the variable for both inequalities. You need to reverse the direction of the inequality symbol when dividing both sides by a negative number.

Car A is traveling east at a steady speed of 45 miles per hour. After 2 hours, it is 100 miles east of Johnstown
Car B is traveling east on the same road. it’s distance east of Johnstown is represented by the graph.
Where were the two cars in relation to each other when they began traveling?
A. Car B was 10 miles east of car A
B. Car A was 45 miles east of car B
C. Car A was 10 miles east of car B
D. Car B was 40 miles east of car A
Answer:
The correct option is;
A. Car B was 10 miles east of car A
Step-by-step explanation:
The given parameters are;
The speed of car A = 45 miles per hour
The direction of car A = East
The distance of car B from Johnstown after 2 hours = 100 miles east
The direction of Car B = East
The distance of car B from Johnstown is given on the graph
Therefore, the initial distance of car A from Johnstown when car A began driving is given as follows;
The initial distance, east, of car A from Johnstown = 100 - 2 × 45 = 10
∴ The initial distance, east, of car A from Johnstown = 10 miles
From the graph, the initial distance, east, of car B from Johnstown = 20 miles
Therefore, car B was 10 miles east of car A
Answer:
Car B was 10 miles east of car A

Step-by-step explanation:
B is between A and C. If AB = 2x + 1, BC = x, and AC = 22. Find AB.
Answer:
15
Step-by-step explanation:
AB + BC = AC
2x + 1 + x = 22
3x + 1 = 22
3x = 22 -1
3x = 21
x = 21/3
x = 7
AB = 2*7 +1
= 14 + 1
= 15
Sarah said that 26÷8 is the same as/equal to 14÷4 and the answers are "3r2". What did Sarah do wrong? 5th grade math help fir my daughter. I think Sarah meant: 26÷8 is the same as or equal to 13÷4 instead of 14÷4 which is what she did wrong?
Answer:
Yes
Step-by-step explanation:
Yes, that is exactly what Sarah did wrong. Apparently, she tried to divide both the numerator and denominator in this problem by 2 (half) but divided the numerator incorrectly. 26 divided by 2 would equal 13 but Sarah mistakenly calculated it as 14 which would give her a totally different value when divided by the new denominator. If were to have divided correctly it would give her [tex]\frac{13}{4}[/tex] which is the same as [tex]\frac{26}{8}[/tex]

Given side lengths 4 units, 8 units, and x units, determine the range in which x must lie in order for a triangle to exist.
A)
X > 12
B)
0
C)-4
D)
4
Answer:
A is the correct answer
Step-by-step explanation:
Mathematically if we have lengths a, b and c
For a triangle to occur, let us say that the third side is c
then a + b must be greater than or equal to c
Hence c must be equal to (4 + 8) or greater than (4 + 8)
With the options given , A is the correct answer

Step-by-step explanation:
Here is a triangle with the height on the side of the triangle. Use the formula: (1/2)*(Base)*(Height) to find the area of the triangle at the left.
(If one square on the graph = one centimeter)
b = 10cm
h = 10cm
Area
[tex] = \frac{1}{2} \times b \times \: h[/tex]
[tex] = \frac{1}{2 } \times 10 \times 10[/tex]
[tex] = \frac{1}{2} \times 100[/tex]
[tex] = 50 {cm}^{2} [/tex]

Which equations illustrate the zero property of multiplication? Select ALL that apply.
[tex] \frac{1}{3} \times 3 - 3 = 4[/tex]
[tex] \frac{1}{2} + 2 - 2 = \frac{1}{2} [/tex]
[tex]0 \times \frac{1}{9} \times 9 = 0[/tex]
[tex]x - 5 + 5 = x[/tex]
[tex] \frac{1}{3}(9 + 3) = 3 + 1 [/tex]
Answer:
0* 1/9*9=0
Step-by-step explanation:
The zero property of multiplication states that any non-zero number multiplied by zero will equal zero.
it can't be the first one, since there's no zero in it, and the answer isn't zero
it can't be the second one since there's no multiplication illustrated.
The third one is an option, since there is a zero and it's being multiplied by two non-zero numbers, and the answer is 0
the fourth one isn't an option since there's no multiplication
the fifth one isn't an option since there is no 0's there.
hope this helps!

Martha states that –6 is a rational number. Which is a correct explanation for this statement?
The number –6 is the opposite of 6.
The number –6 is a negative integer.
The number –6 can be written as -6/1.
The number –6 is less than 0.
can someone plz help i need to graph it and identify the x-intercept
Answer:
(-7/2,0) is the x intercept
Step-by-step explanation:
1. y+3 = -6/7x
2. -3 -3 ....subtract 3 from both sides to isolate the variable y
y= =-6/7x -3 ....is your new equation
You graph it by putting your point on negative three and then counting 6 units down and 7 units right.
For the x intercept you set y to 0 and solve for x
0= -6/7x -3
+3 +3 ...to both sides
3= -6/7x .....divide both sides by -6/7
-7/2=x
