Answer:
Step-by-step explanation:
Given
time taken by Carlos to cycle is 
For case (1)
Average speed 
For 
Distance traveled 
Therefore Carlos might not be able to cover 6 miles with average speed of 16 ft/s
(2)
for 0.5 hr
distance traveled
Therefore Carlos might be able to cover more than 6 miles with 
1/5
because if you divide it by 12, 1/5 will be your answer
A/4 = b/7 Cross multiply: 7a =4b Divide by b: (7a/b)=4 Multiply by 1/7: a/b =4/7
4/7 is your answer
Eliminate the x terms: Multiply the second equation by 2
-10x+12y=20
Add it to the first equation
10x-4y=-8
-10x+12y=20
——————-
0x+8y=12
y = 1.5
10x-4(1.5)=-8
10x = -2
x = -1/5
Answer:
When given 2 sides of a triangle, the third side must be:
Greater than the difference of the other 2 sides AND
less than the sum of the other 2 sides.
So side "x" must be greater than
(8 -5) and less than (8 +5) or
3 < "x" < 13
