Answer:
BMX Ben is correct and Pizza Pete is wrong
Step-by-step explanation:
For Both equations, we must isolate the x, or move everything to one side. So you'd have to add 25 because you have a negative 25 and a negative number plus a positive version of itself equals 0
x-25=7
+25=25
__________
x=32
The second one is incorrect because you are subtracting negative 25 from a 25, which is -50

Give your answer as an improper fraction in its simplest form.
y =
Answers
Answer:
x = -3; substitute it to the other equation.
2(-3) - 7y = 30
-6 - 7y = 30
-7y = 30 + 6
-7y = 36
y = -36/7
we will not round the number because the question is asking for an improper fraction at its simplest form.
Answer:
5.1
Step-by-step explanation:
2*-3 - 7y =30
-6 + 7y = 30
7y = 30 + 6
y = 36 / 7
i.e. y = 5.1
It is 6.417.5 km from Indianapolis to London, England. The Flash can make this trip in 1
hour and 35 minutes. How fast is this in miles per hour?
Answers
Answer:
[tex]Speed = 2519.58 mph[/tex]
Step-by-step explanation:
Given
[tex]Distance = 6417.5km[/tex]
[tex]Time = 1\ hr: 35\ mins[/tex]
Required
Calculate the speed in miles per hour
Convert distance to miles
[tex]Distance = 6417.5km[/tex]
[tex]Distance = \frac{6417.5km}{1.609}\ miles[/tex]
[tex]Distance = 3988.50217526\ miles[/tex]
[tex]Time = 1\ hr: 35\ mins[/tex]
Divide minutes by 60
[tex]Time = 1\ hr + 35/60[/tex]
[tex]Time = 1\ hr + 0.583\ hr[/tex]
[tex]Time = 1.583hr[/tex]
The speed is:
[tex]Speed = Distance/Time[/tex]
[tex]Speed = 3988.50217526/1.583 mph[/tex]
[tex]Speed = 2519.58 mph[/tex]

The average mass of an adult human is about 65 kilograms while the average mass of an ant is approximately 4×10−3 grams. The total human population in the world is approximately 6.84 billion, and it is estimated there are currently about 10,000 trillion ants alive. Based on these values, about how many times greater is the total mass of living humans compared to the total mass of all living ants? Round to the nearest whole.
Answers
Find total mass:
Human: 65 kg x 6,840,000,000 = 444,600,000,000 kg
Ants: 4x10^-3 = 0.004g
0.004 x 10,000,000,000,000,000 = 40,000,000,000,000g
Divide total grams by 1000 to get kegs:
40,000,000,000,000 /1000 = 40,000,000,000 kgs.
Divide total mass of humans by total mass of ants:
444,600,000,000 / 40,000,000,000 = 11.115
Mass of humans is 11.115 times more than ants.
Rounded to the nearest whole number = 11 times more.

Which graph represents the function?
f(x)={3ifx<1xifx≥1
Answers
Answer: The graph in the bottom right corner.
Step-by-step explanation:
We have the function:
f(x) = 3 if x < 1.
f(x) = x if x ≥ 1
First, let's analyze each part of the function:
f(x) = 3 if x < 1.
We have a constant line y = 3, such that it ends at the point x = 1 with an open dot (or white dot) (because here we have the symbol <)
f(x) = x if x ≥ 1
From x = 1 and on, we have the line y = x, such that in the point x = 1 we will have a closed dot (or black dot) that means that the point does belong to the graph.
when x = 1, we have:
f(1) = 1
Then we will have the closed dot at the point (1, 1)
Then the correct option is the one in the bottom right.
Answer:
The answer is The graph on the bottom right

Complementary angles
Answers
============================================================
Explanation:
The square marker indicates a 90 degree, or right angle.
The two smaller angles (3x and 75) both combine to the larger 90 degree angle. That's what it means when they say we have complementary angles.
Add up the smaller angles, set the sum equal to 90, and solve for x.
3x+75 = 90
3x+75-75 = 90-75 ....... subtracting 75 from both sides
3x = 15
3x/3 = 15/3 ..... divide both sides by 3
x = 5
---------------
If x = 5, then 3x = 3*5 = 15
Then we can see that 15+75 = 90 to help check our answer.

What function is the inverse of the exponential function y = 3^x?
Answers
Answer:
Step-by-step explanation:
First switch the y and x values:
[tex]x=3^y[/tex]
Take the natural log of both sides to get:
[tex]\ln(x)=y*\ln(3)[/tex]
Separate the y value:
[tex]y=\frac{\ln(x)}{\ln(3)}[/tex]
The inverse of the exponential function will be:
"y = [tex]\frac{ln(x)}{ln(3)}[/tex]".
Exponential functionAccording to the question,
The function, y = [tex]3^x[/tex]
By switching "x" and "y" of both sides of the function,
→ x = [tex]3^y[/tex]
Now,
By taking "log" both sides,
ln(x) = y × ln(3)
By separating the terms, we get
y = [tex]\frac{ln(x)}{ln(3)}[/tex]
Thus the above response is correct.
