Solve the math equations

1)a= 16

2)x= 4

3)x= 0

4)n= -20

5)r= 20

6)x= -11

7)v= 15

8)n= -6

9)x= 9

10)n= 8

11)v= -16

12)x= -17

Step-by-step explanation:

if if you need a specific problem worked out comment it.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
