Tony is 1/2 of a mile ahead of Laura on a jogging path. If Tony is running at 5 miles per hour, and Laura is running at 7 miles per hour, how long will it take Laura to catch up with Tony?
Answer: Another way of looking at this problem, is that Laura will "gain" 2 miles on Tony in 1 hour. Why? She is going 7 miles in 1 hour, while Tony is only going 5. 7-5 = 2.
However, Tony is only .5 miles ahead and the question asks how long will it take for her to catch up, not to overtake him or beat him in some race.
I would make a simple ratio here. If in 1 hour/she beats him by 2 miles, x hours/she beats him by .5 miles.
Another way to write that is 1/2 = x/.5
If you solve the equation, you get (by cross-multiplication) 2x = .5, x = .5/2, x =1/4.
Now, we are dealing with hours, so since there are 60 minutes in one hour, multiple the value you obtain for x by 60 minutes (60*1/4) = 15 minutes.
Therefore, it will take Laura 1/4 of an hour, or 15 minutes, in order to catch up with Tony

if the spinner lands on green 10 times out of 60 spins,which statement true
Answer:
The spinner lands on green 5 times less than expectedStep-by-step explanation:
Since not provided, it is assumed that the spinner has 4 colors.
Probability of green is one out of four = 1/4
Probability of green out of 60 spins:
1/4*60 = 15 timesAs spinner lands on green 10 times, then it is 5 times less than expected.
Answer:
The spinner lands on green 5 times less than expectedCompare an angle having a measure of 120° With that of an angle whose measure is five pi over 6 rad explain your reasoning
Answer:
Step-by-step explanation:
et A=120°
and B=5Pi /6
Pi radians ---------> 180°
x<----------------------- 120°
so x =120 x Pi / 180 = 12 xPi / 18 = 2 Pi/3
so A = 2Pi / 3 radian
let 's compare A and B
we know that 5Pi /6 = 0.8 Pi and 2P/3= 0.6 Pi, 0.8>0.6,
finally 5Pi /6 > 2P/3
so B>A
1)n/5=-10 How do we answer this question
Answer: Your answer will be [tex]\frac{-50}{5} =-10[/tex]
Step-by-step explanation: You will have
[tex](5)\frac{n}{5} =-10(5)[/tex] you will have to multiply 5 on both sides. So you will then simplify 5 and 5 to be left with n and multiply -10(5)=-50
So you get [tex]n=-50[/tex]
Write the domain and the range of the function as an inequality, using set notations, and using interval notation. Also describe the end behavior of the function or explain why there is no end behavior (19 points and brainliest)
Answer:
Step-by-step explanation:
I think we need to define domain and range first.
Domain is the set of all x values where the function f(x) exists or is defined.
Range is the set of all y values that will result from substituting all x values (the domain) into the function.
So for g(x) = 2x - 2 we can evaluate g(x) at any point, and we will get a real answer for y.
So the range of g(x) = 2x -2 is also all real numbers, because no matter what value of x is, we can always multiply that number by 2 and subtract 2.
The inequality does not affect the domain and range of linear functions at all. Don't confuse domain and range with a solution to an inequality. These two concepts are different. Domain and range mean all possible values of x and y that could be substituted into the inequality. A solution means all possible values that make the inequality statement true.
The domain as an inequality would be -∞ < x < ∞
The range as an inequality would be -∞ < y < ∞
As a set notation:
Domain {x | -∞ < x < ∞}
Range {y | -∞ < x < ∞}
In interval notation:
Domain (-∞ , ∞)
Range (-∞ , ∞)
End behavior:
As x gets larger and larger, g(x) gets larger and larger as well, and as x gets smaller, g(x) gets smaller too.

How many solutions does this equation have?
-4 + 6n
7n
no solution
one solution
infinitely many solutions
Answer:
One solution
Step-by-step explanation:
-4 + 6n = 7n
you will subtract (6n-6n) which will cancel each other out, than subtract (7n - 6n) which will be (1n)
So now you will have -4 = 1n
Now you will divide ( -4/1) which is -4
You don't have to divide -4 with 1, because its the same way as multiplying it.
Now you will have -4 = n

Keith wentfor drive in his new car he drove for 86.4 miles at a speed of 54 mph for how many hours did he drive
Complete the following statement.
16/
= -8
16 / x = -8
First, let's divide both sides by x.
16 = -8x
Divide both sides by -8
-2 = x
16 / -2 = -8
Answer:
m = -2
Step-by-step explanation:
16 / m = -8
→ 16 = -8m
→ m = 16/-8
→ m = -2
3 is subtracted from the cube of a number.
The equation [tex]x^{3} - 3[/tex] has x values as 0, [tex]\sqrt{3}[/tex] and -[tex]\sqrt{3}[/tex].
We are given,
3 is subtracted from the cube of a number.
Let the number be x then we can write it as:
[tex]x^{3}[/tex] - 3
We are to solve for x.
We can write the equation as:
[tex]x^{3}[/tex] - 3 = 0
x ( [tex]x^{2}[/tex]- 3 ) = 0
x = 0 and ( [tex]x^{2}[/tex] - 3 ) = 0
x = 0 and [tex]x^{2}[/tex] = 3
x = 0 and x = ±[tex]\sqrt{3}[/tex]
So we have,
x = 0, [tex]\sqrt{3}[/tex] and -[tex]\sqrt{3}[/tex]
Thus we have x values as 0, [tex]\sqrt{3}[/tex] and -[tex]\sqrt{3}[/tex].

Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
x=16
Step-by-step explanation:
its C
Answer:
x=16
Step-by-step explanation:
First of all we want to distribute 0.5 on 5x and -8
so we are going to divide by 2
1.5x + 12 = 2.5x -4
now we want to put the variables on one side and the numbers on the other side of the equal sign
and to
1.5x +12 = 2.5x -4
-12 -12
1.5x = 2.5x - 16
now we want to move the variable that is on the right to the left side
1.5x = 2.5x - 16
-2.5x -2.5x
-x = -16
change the signs and the answer is
x=16

QR has endpoints at Q(2,6) and R(0,2). Find the midpoint M of QR
Answer:
Step-by-step explanation:
Well, the midpoint formula is M=((x↓1 +x↓2)/2,(y↓1 +y↓2)/2 ). (not exponents, they tell you which x or y value).
If you plug in your 2 points, it becomes m=((2+0)/2,(6+2)/2).
When you add, it is m=(2/2, 8/2)
When simplified, it is m=(1,4)
AC CE and D is the midpoint of CE. IF CE 10x + 18, DE =7x -1, and BC = 9x - 2, find AB, AB =
Answer:
If you mean: AC=CE, the answer is: AB = 24Step-by-step explanation:
D is the midpoint of CE, then
CD = DE = 0.5CE = 0.5(10x+18) = 5x + 9
So: 5x + 9 = 7x - 1
-9 -9
5x = 7x - 8
-7x -7x
-2x = -8
÷(-2) ÷(-2)
x = 4
AC = CE = 10x + 18 = 40 + 18 = 58
BC = 9x - 2 = 36 - 2= 34
AB = AC - BC = 58 - 34 = 24
D is the midpoint of CE, so if you draw a line with those three points, it'll look like C-D-E.
Since DE = 7x-1, which also means CD = 7x-1.
CD + DE = CE, so (7x-1)+(7x-1) = 10x+18.
Therefore, x = 5 and CE = 68.
Since AC is congruent to CE, AC = 68.
Assuming the point B is somewhere between AC.
Since BC = 9x-2 and x = 5, which means BC = 43.
AC - BC = AB, so 68 - 43 = 25.
Therefore, AB = 25

To solve this problem, you have to know that the measure of all the angles of a triangle is equal to 180 degrees.
Let's add each angle together and set them equal to 180 degrees.
180 degrees = 3x + 2x + 1 + x + 5
Combine like terms
180 degrees = 6x + 6
Subtract 6 from both sides
174 degrees = 6x
Divide both sides by 6
29 = x
We know that angle A = 3x = 3(29) = 87 degrees.
