Answer:
5≤x≤31/3
5, is less than or equal to, x, is less than or equal to, start fraction, 31, divided by, 3, end fraction
Step-by-step explanation:
Given two inequalities
3x-8≤23 and −4x+26≥6
Solving both individually for x
For the inequality 3x-8≤23
Moving -8 to the other side;
3x ≤ 23+8
3x≤31
x≤31/3... 1
For inequality −4x+26≥6
Taking 26 to the other side, we have:
-4x ≥ 6-26
-4x ≥ -20
Dividing both sides by -4
x≥20/4 .
x≥5 ... 2
Combining both inequality 1 and 2, we have:
5≤x≤31/3
Square root of 25 is 5
- sqrt25 = - 5
This is an integer
First, we are going to find the distance traveled by the ship adding the tow distances:
Distance traveled= 24 mi +33 mi=57 mi
Next, we are going to use the Pythagorean theorem to find the distance from
to
:
d^2=1665
mi
Finally, we are going to subtract the two distances:
57 mi -40.8 mi= 16.2 mi
We can conclude that <span>if the ship could have traveled in a straight lime from point a to point c, it could have saved
16.2 miles.</span>
Find common denominators
2/20+3/20
then multiply 3x4=12/20
then 2x5=15/20
last add that 27/20
