Answer: a1=6
An = An-1 - 4
Step-by-step explanation:
N represent what number in the sequence you choose. So in the equation n-1 would be the umber in the equation subtracting 1 then subtracting the difference. The factor you are multiplying by in this sequence is -4. You find the difference by taking any number in the sequence and dividing it by the previous number in the sequence.
Answer:
-5
Step-by-step explanation:
9x +18=-27
9x = -27 -18
9x =-45
x = -45/9
x = -5
x= the number
0 solution
3(x+4)=3x+4
3x+12=3x+4
(3x-3x)=(-12+4)
0=-8
so no posible solution
Linear pairs add up to 180 degrees.
x=4y-5
x+y=180
Substitute x
4y-5+y=180
5y-5=180
5y=185
y=37
Plug the y value in
x+37=180
x=143
Final answer: angle 1= 143 degrees, angle 2= 37 degrees
Answer:
C
Step-by-step explanation:
180 - 42 - 38 = 100
