what is the value of n in the equation 2n+19=21
Step-by-step explanation:
[tex]2n + 19 = 21[/tex]
[tex]2n = 21 - 19[/tex]
[tex]2n = 2[/tex]
[tex]n = 2 \div 2[/tex]
Therefore, N = 1
hope it helps don't forget to like and mark me down
Answer:
n=1
Step-by-step explanation:
to solve this you put 19 on the opposite side and subtract 19 fron 21 because subtraction is the opposite of addition and then you get 2 and then divide 2 by 2 to get 1 so n=1. Yo can check it by doing 2*1=2 then 2+19 =21 so it is the correct answer.

The NYC subway system has a total of 850 miles of train tracks, and a NYC subway train has an average speed of 17.4 mph. If you laid all 850 miles of track end-to-end in one big circle, how much time would it take to ride a NYC subway train around the entire circumference of that circle?
Answer:48.85 hr
Step-by-step explanation:
Given
The length of the train track is [tex]L=850\ miles[/tex]
the average speed of the train is [tex]v_{avg}=850\ mph[/tex]
If this track is laid on to a big circle, then the length is equivalent to the circumference
time is taken to cover the circumference is given by
[tex]\Rightarrow t=\dfrac{L}{v}\\\\\Rightarrow t=\dfrac{850}{17.4}=48.85\ hr[/tex]
x is an odd number and the sum of the next two consecutive even numbers is less than 90.
By forming an inequality in terms of x, find the largest possible odd number of x.
Answer:
41
Step-by-step explanation:
Let the odd number be x
Therefore,
[tex](x + 1) + (x + 3) < 90 \\ 2x + 4 < 90 \\ 2x < 86 \\ x < 43[/tex]
Therefore, Largest possible odd number of x is 41
anyone know how to do this?
Answer:
[tex]5 = 16 - 11 \\ so \: \\ {x}^{2} - 8x + 16 - 11\\ \\ {x}^{2} - 8x + 16 = (x - 4)^{2} \\ \\ (x - 4)^{2} - 11 [/tex]

Answer:
b) $0.50, it represents the price per mile to drive the rental van.
Step-by-step explanation:
Find the slope by taking 2 points from the graph: (20, 40) and (40, 50)
Use the formula to find the slope: y2 - y1/ x2 -x1
Substitute the values into the formula above:-
50 - 40 / 40 - 20
=> 10/20
Simplify
=> 1/2
=> 1/2 = 0.50
The slope is $0.50

=75A car accelerates from rest to 25 miles per hour in 3.0 seconds. What was the car's
acceleration?
Answer:
The car's acceleration was 3.73 metre per second square = 3.73m/s²
Step-by-step explanation:
The car accelerated from rest.
initial velocity (u) = 0m/s
final velocity (v) = 25miles/hr = 11.2m/s
time (t) = 3s
a = ?
v = u+at
a = (v-u)/t
a = (11.2 - 0) / 3
a = 11.2/3
a = 3.73
a = 3.73m/s²

Find the solutions to x2 = 27.
O A. x = +3,5
B. x = +39
O C. x = +9.12
D. X = +9.5
Answer:
A
Step-by-step explanation:
Given
x² = 27 ( take the square root of both sides )
x = ± [tex]\sqrt{27}[/tex]
= ± [tex]\sqrt{9(3)}[/tex]
= ± [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex]
= ± 3[tex]\sqrt{3}[/tex] → A

Write a linear function f with the given values. f(0) = 7, f(3) = 1
Answer:
So the slope in this case is m = -2. Using point (0, 7) and m =-2 with point-slope we have y - 7 = -2(x-0) => y = -2x +7. Then we realize (0,7) actually is the y-intercept. We could have gone directly to y = -2x + 7. If we use (3,1) and m = -2 we get y-1=-2(x-3) => y -1 = -2x+6 => y = -2x+7. Another way to find y-intercept is to use y = mx +b directly. If we use the point (3,1) that means when x=3, y = 1. So 1=-2(3) + b => 1=-6+b => b = 7. So, y = -2x+7. Same result in all cases. I like to use point-slope. Others prefer to use y = mx+b, substituting for x, y, and m to solve for b.

The perimeter of a scalene triangle is 90 feet. The first side is three times the third minus six. The second side is twice the third plus three. How long is the third side?
Answer:
15.5
Step-by-step explanation:
3rd side =x
3x-6 +2x-3+x =90
6x-3 =90
6x =93
x= 15.5
3(15.5)-6=40.5
2(15.5)+3=34
40.5+34+15.5 =90
What is the sum of the geometric sequence 1, 4, 16,
if there are 8 terms?
21,845
43,690
65,535
87,380
Answer:
The sum of geometric sequence:
S n = a 1 * ( q^n - 1 ) / ( q - 1 )
where: a 1 = 1,
q = a 2 : a 1 = 4 : 1 = 4
S 8 = 1 * ( 4^(8) - 1 ) / ( 4 - 1 ) =
= ( 65,536 - 1 ) / ( 4 - 1 ) = 65,535 / 3 = 21,845
