Answer:
No solutions! :)
Step-by-step explanation:
To find the number of solutions in a problem we must solve it.
x+2x+7=3x-7
Firstly, combine common terms:
3x+7=3x-7
We can subtract 3x from both sides:
7=-7
The solution is 7=-7, which is no solution.
When a number is equal to a number in a solution, it has no solutions!

Step-by-step explanation:

Solve
x + y = 100 x -y = 10
Pair of Equation
lets take
x+y=100 firstly.
then x=100-y equation (i)
Now,
x-y=10
Putting value of x from equation(i)
100-y-y=10
-2y=10-100
-2y=-90
therefore, y=45
Now,
putting value of y in equation(i)
we get
x=100-45
ie x=55
hence, x=55 & y=45
Answer:
The solution is (55, 45).
Step-by-step explanation:
Solve the system of linear equations
x + y = 100
x - y = 10
through elimination by addition / subtraction.
Combining these two equations temporarily eliminates y, leaving us with 2x = 110. Then x = 55.
Substituting 55 for x in the first equation, we get:
55 + y = 100. Subtracting 55 from both sides leaves us with y = 45.
The solution is (55, 45).

What is the equation for -2 = m divided by 16
Answer:
-2 = [tex]\frac{m}{16}[/tex] or [tex]\frac{m}{16}[/tex] = -2
Step-by-step explanation:
A line passes through the point (12,0) and is parallel to the line with the equation y = 1∕6x + 1. What's the equation of the line?
Answer:
y=1/6x-2
Step-by-step explanation:
Parralel lines have the same slope.
Since the slope of the parralel equation has to be 1/6, and the point is (12,0)
then you input 12 for x and get 2. But you need to get 0 for y, so the intercept would be negative 2.

Approximately 0.45 m. A mountain bike tire has a diameter of approximately. 0.6 m. In a 400-m race, how many more times will the BMX bike tire have to turn than the mountain bike tire?
Answer:
71 times
Step-by-step explanation:
Diameter of BMX bike= 0.45m
Radius= 0.225m
Cirumference of BMX bike
C= 2πr
C=2*3.142*0.225
C= 1.4139m
In a 400-m race, the BMX bike will turn
=400/1.4139
=282.9 times
=283 times
Diameter of Mountain bike= 0.6m
Radius= 0.3m
Circumference of Mountain bike
C= 2πr
C=2*3.142*0.3
C=1.8852m
In a 400-m race, the Mountain bike will turn
=400/1.8852
=212.17 times
=212 times
Hence the difference is
=283 -212
=71 times

An engineer is standing 250 meters away from a building. She measures the angle of elevation to the top of the building to be 30 degrees. How tall is the building, rounded to the nearest meter?
Answer:
144m
Step-by-step explanation:
we would used tan 30 to determine the height of the building
tan 30 = opposite / adjacent
0.5774 x 250 = 144m
