Add 3x to both sides of the equation which means y=13+3x
The answer depends on whether you're looking for the x or the y. If y, the answers are the ones on the left, and the x on the right.
1) -4x + 3y ≤ 15 -4x + 3y <span>≤ 15
</span><span> +4x +4x -3y -3y
3y </span>≤ 4x + 15 -4x <span>≤ -3y + 15
</span><span> --- --------- ---- ------------
3 3 -4 -4
y </span>≤ 4/3x + 5 x <span>≥ 3/4y + 11
2) -6x - 4y </span>< 12 -6x - 4y < 12<span>
+6x +6x +4y +4y
-4y </span>< 6x +12 -6x < 4y + 12<span>
---- ---------- ---- -----------
-4 -4 -6 -6
y </span>> -3/2 - 3 x > -2/3y - 2
Answer:
Hey!
To start this problem, we'll most likely need a calculator. Handling
can get a little messy, and tricky.
(also note that "pie" is a food, the mathematical term
, is pronounced "pie", but spelled "pi.")
Anyway, multiplying 3.14159265359..... (
)
160 = 502.654824574...... going on and on.
In general, these types of problems are better for a calculator if you want an exact answer. Otherwise, just resort to estimation.
is pretty close to 3.14.
160
3.14 = 502.4, which is decently close to our other answer.
Hope this helps!

Use the formula SA=a+1/2ps
a=area of the base
p= perimeter of the base
s= slant height
