SMART PEOPLE PLEASE HELPI HAVE POSTED THIS 6 TIMES

i said this first. I hope this helps.

2x = 5

x = 5/2

y + 1.8 = 14.7

Y = 12.9

6 = 1/2z

z = 12

3 1/4 = 1/2 + w

w = 11/4= 2.75

2.5t = 10

t=4

1.  x = 2.5

2. y = 12.9

3.  z=3

4. w= 2 3/4

5. t= 4

Step-by-step explanation:

1.  5 DIVIDED BY 2= 2.5

2.  14.7 - 1.8 = 12.9

3.  1/2 * 3 = 6

4.  1/2 + 2 3/4 = 3 1/4

5.  10/ 2.5 = 4

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
