<span>solve -2(2x + 5) - 3 = -3(x - 1)
-4x - 10 -3 = -3x + 3
-4x - 13 = -3x + 3
Add 3x to both sides
-4x - 13 +3x = -3x +3
Simplify
-x - 13 = 3
Add 13 to both sides
-x - 13 + 13 = 3 + 13
Simplify
-x = 16
multiply both sides by (-1)
x = -16</span>
Answer:
Step-by-step explanation:
GIven that :
(a) lim (x,y)→(0,0) 5x + y √ 5x + y + 9 − 3
(b) lim (x,y)→(0,0) 2xy x 2 + y 2
We are to evaluate and determine if the limit exist or not.
From (a);
x = 0
y = 0 (Since no presence of indeterminate)
=
= 0+0+0 +9 - 3
= 6
Therefore; the limit exist
(b)
If y = mx
So; the limit depends on the value of m; then the limit does not exist

Answer:
10%
Step-by-step explanation:
Amount of salt in 90g of water = 10g
Total weight of solution (salt + water) = (10g + 90g) = 100g
=> Total weight of salt in 100g of solution = 10g
Hence, Percentage of salt in this solution is given by:
This corresponds to 10%
So the percentage of salt in the solution = 10%
Similarly, percentage of water in the solution = = 90%
