Answer:
n = -2
Step-by-step explanation:
6n = 2n-8
4n = -8
n = -2
3x-11=x+23
-x -x
2x-11=23
+11 +11
2x=34
x=17
3(17)-11 17+23
=40 =40
explanation ;
you would equal them because they are congruent . & you substitute x for 17 in each equation to find out the degrees of both of the angles :)
The equation for a equilateral triangle is the side squared times root 3 divided by 4
"Minute" is a unit of time, whereas "mile" is a unit of length or distance.
They have different physical dimensions, they measure different quantities,
and they can't be converted one to the other.
If distance could be converted to time, then it would be possible for you ...
or a more mathematically capable acquaintance ... to calculate how many
minutes long your dog's tail is.
For finding the value of b, we must consider that Line MN passes through points M(4, 3) and N(7, 12). With this condition y = mx + b, can be written 3=4m+ b (because line passes through M(4,3) ) and 12=7m+b, b ( because line passes through M(7,12)).
We have a system of equation
4m+ b=3
7m+b=12
For solving this, 4m+b- (7m+b)= 3-12, it is equivalent to -3m= -9 and then m=3, if m=3 so
4x3 +b =3 implies b= 3 -12= -9, so the value of b= -9
