Answer: 90
cuz if you use the ruler thing it gives you 90 trust me
Answer:
x=16
Step-by-step explanation:
1/2 ( x - 4 ) = 1/3 ( x + 2)
distribute both sides

(x+2)
(

Step 2: Subtract 1/3x from both sides.

Step 3: Add 2 to both sides.

Step 4: Multiply both sides by 6.

x=16
You owe half of 272 which is 136
70.8 fish tanks. Because you have to divide 354 by 5.
For easier notation lets use: Nn=x and Nd=y
x+y=22
5x+10y=135
Multiply the first equation by 5 to get
5x+5y=110
Now you can eliminate x by subtracting the first equation from the second
5x+10y-5x-5y=135-110
5y=25
y=5
x=17
