Answer:
The value of 2n - 2 is 4.
Step-by-step explanation:
Given the equation
[tex]n + 7 = 10[/tex]
Subtract 7 from both sides of the equation
[tex]n+7-7=10-7[/tex]
Simplify
[tex]n=3[/tex]
Now substituting n = 3 in the equation
2n - 2 = 2(3) - 2
= 6 - 2
= 4
Therefore, the value of 2n - 2 is 4.

ILL GIVE BRAINIEST find the solption for each system of equations using substitution. check ur solution in both original equations and make sure equations are in slope intercept form before u set them equal
y= -2x+6 and y=3x-4
check:
Answer:
X= 2
y = 2
Step-by-step explanation:
y=-2x+6............... equation 1
y=3x-4................... equation 2
from equation 2
y=3x-4
substitute y=3x-4 in equation 1
3x-4=-2x+6
collect like terms
3x+2x=6+4
5x=10
divide both sides by 5
X=2
substitute X=2 in equation 1
y=-2x+6
y=-2(2)+6
y=-4+6
y=2

The Earth has a diameter
of 7,917.5 miles. What is
the distance a plane
would have to fly if it
could fly around the entire
equator?
Answer:
L = 24,873.6 miles
Step-by-step explanation:
Length of the Circumference
Given a circle of radius r, the length of the circumference, or line surrounding the shape is:
[tex]L =2\pi\cdot r[/tex]
The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:
r=7,917.5/2=3,958.75 miles
Assuming a plane flies around the equator at ground level, the distance it would travel is:
[tex]L =2\pi\cdot 3,958.75\ miles[/tex]
L = 24,873.6 miles

x + 5y = 16
x + 3y = 10
Answer: x=1 and y=3
Step-by-step explanation: hope this help
The solution of the linear equations x + 5y = 16 and x + 3y = 10 will be (1, 3).
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The linear equations are given below.
x + 5y = 16 ...1
x + 3y = 10 ...2
Subtract equation 2 from equation 1, then we have
x + 5y - x - 3y = 16 - 10
2y = 6
y = 3
Then the value of the variable 'x' will be given as,
x + 5(3) = 16
x + 15 = 16
x = 1
The solution of the linear equations x + 5y = 16 and x + 3y = 10 will be (1, 3).
More about the solution of the equation link is given below.

The product of 3 and a number equals the sum of 16 and a number.
Answer:
The numbers can be either -8,-7,-6, or 6, 7, 8.
n(n−1)(n+1)=16(n−1+n+n+1)
⟹n(n2−1)=16×3n
⟹n(n2−1)n=48nn
⟹(n2−1)−48=48−48
⟹n2−49=0
⟶(n−7)(n+7)=0
n can be 7 or −7 , so the numbers can be either −8,−7,−6
Or
6,7,8

If an object was dropped from a height of 405 Meters,find the time it took for the object to hit the ground
Answer:You can use the concept of conservation of total mechanical energy (neglecting the air resistance).
So, initially total mechanical energy = gravitational potential energy (kinetic energy is zero because initially there is no velocity).
Final total mechanical energy = kinetic energy (gravitational potential energy is zero because height has become zero).
So, initial mechanical energy = Final mechanical energy

First, let's solve the subtraction (in parentheses):
[tex]\mathsf{\dfrac{-8\left(2-6\right)}{2}}[/tex]
[tex]\mathsf{\dfrac{-8(-4)}{2}}[/tex]
Now, let's solve the multiplication. Remember: in multiplication, two negative numbers will give a positive number:
