Helpp pleasee it's solving mulit=step equations.

Step-by-step explanation:

1. x+5=3

x= 3-5=-2

2. m-4=19

m= 19+4=23

3. a÷6=-4

Multiply by 6 on both sides we get

a = -4×6=-24

4. -6x =-36

Divide by -6 on both sides

x =6

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.
