Andre ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. Did they run at the same speed?
Answers
Answer:
speed of Jada = 6km per hour which is not equal to
speed of Andre = 8km per hour
They did not run at same speed
Step-by-step explanation:
formula of speed = distance covered/ time taken
For Andre
Distance = 2 KM
time = 15 mins
60 mins = 1 hour
15 mins = 1/60 * 15 hour = 0.25 hours
thus,
speed = 2km/0.25 hour = 8 km per hour
Similarly for Jada
Distance = 3 KM
time = 20 mins
60 mins = 1 hour
20 mins = 1/60 * 20 hour = 1/3 hours
thus,
speed = 2km/(1/3)hour = 6 km per hour
Now we have
speed of Jada = 6km per hour which is not equal to
speed of Andre = 8km per hour

b. 6 more than a # k is less than or equal to 12
Answers
Answer:
I think the answer is B
Step-by-step explanation:
The inequality that represents "all real number's 'x' greater than 2" is [tex]x > 2[/tex] and the inequality that represents "6 more than a number 'k' is less than or equal to 12" is [tex]6 + k \leq 12[/tex].
a)
Given :
All real number's 'x' greater than 2
So, the inequality that represents the given verbal expression is given below:
[tex]x > 2[/tex]
where 'x' is the real number.
b)
Given :
6 more than a number 'k' is less than or equal to 12.

Answers
Answer:
im pretty sure the answer is ∠e and ∠i; ∠f and ∠g
but if not im so sorry :(
Answer:
The third answer
Step-by-step explanation:
Each angle on both triangles has a set of lines, either one, two, or three. These lines are used to show congruency over a number of lines or angles. So one angle will correlate with whatever other angles have that same number of lines. For example, e and g both have two lines, this means they are corresponding and congruent.

What is the solution to -2(8x-4) is less than 2x+5?
Answers
Answer:
=−16x+8 for -2(8x-4)
Step-by-step explanation:
What is the solution to -2(8x-4)= -8x
What is the solution to 2x+5= 7x
so that means -2(8x-4) is less than 2x+5.
Answer: x > 1/6
Step-by-step explanation:
-2(8x - 4) < 2x + 5
Distribute:
-16x + 8 < 2x + 5
Subtract 2x from both sides:
-18x + 8 < 5
Subtract 8 from both sides:
-18x < -3
Divide both sides by -18:
x > 3/18 BUT this simplifies to:
x > 1/6
The reason the inequality flipped is because you divided both sides by a negative number.
The inequality ONLY flips when you divide or multiply both sides by a NEGATIVE number.

The difference of six times a number and seven results in 35.
Identify the steps necessary to solve the equation.
Answers
Answer:
Let the number be x
According to the question,
6x -7 = 35
=> 6x = 35 + 7
=> x = 42/6
=> x = 7
The solution to the equation is x = 7.
We have,
Let's assume the unknown number is represented by the variable 'x'.
- Translate the given information into an equation:
6x - 7 = 35.
- To isolate the variable 'x', start by adding 7 to both sides of the equation:
6x - 7 + 7 = 35 + 7.
- Simplify:
6x = 42.
- Next, divide both sides of the equation by 6 to solve for 'x':
(6x)/6 = 42/6.
x = 7
Therefore,
The solution to the equation is x = 7.

36 + 24 = 60
60 + 18 = 78
78 + 24 = 102
102 + 18 = 120
There are two total long-sleeve shirts and four total short-sleeve shirts.

Which graph represents the function f(x) = –|x + 3|?
Answers
Answer:
Step-by-step explanation:
f(x) = –|x + 3| is a case of the absolute value function
f(x) = -|x - {a}| + c, where (a, c) is the vertex. Comparing them, we see that
the value of a must be -3 and that of c must be 0.
Thus, the vertex of the graph is at (-3, 0), and the graph opens up; it looks like a "v" shape.
