Answer:
x = -22
Step-by-step explanation:
2(5– x)3 – 11 = 151
(10 - 2x)3 - 11 = 151
30 - 6x = 162
-6x = 132
x = -22
Answer: " x = -7 " .

Given: " ln (3x + 5) = ln (2x <span>− 2) " ; Solve for "x" .
_________________________________________________________
Remove the "ln" on both sides of the equation:
We have:
" 3x + 5 = 2x </span><span>− 2 " ;
Add "2" to each side of the equation; & subtract "2x" from each side of the equation:
3x + 5 + 2 </span>− 2x = 2x − 2 + 2 <span>− 2x ;
to get:
x + 7 = 0 ;
Now, subtract "7" from each side of the equation;
to isolate "x" on one side of the equation; & to solve for "x" ;
x + 7 </span>− 7 = 0 <span>− 7 ;
to get:
_________________________________________________________
</span> x = - 7 .

The answer is: " x = - 7 " .

Answer:
140 miles
Step-by-step explanation:
Given:
The scale on Chelsea's map is 1 inch equals 35 miles.
Distance between two cities on the map = 4 inches

Solution:
1 inches = 35 miles
Multiply both sides by 4.
4 inches = 4 × 35 miles = 140 miles
So,
The distance between two cities in miles is 140 miles.
