Answer:
Step-by-step explanation:
Let x represent his average walking speed.
If the average speed on the bike is 8 mph faster than his walking speed,it means that his biking speed is (x + 8) mph
Distance = speed × time
Alex returns a bike to a friends house from his own house in 1/2 hour. This means that the distance covered is
0.5(x + 8)
He walks back over the same route in 1.5 hours. This means that the distance covered is
1.5x
Since the distance covered is the same, then
1.5x = 0.5(x + 8)
1.5x = 0.5x + 4
1.5x - 0.5x = 4
x = 4 mph
Therefore, the distanceof Alex's house from his friend's house is
4 × 1.5 = 6 miles
So if you divide 78 by six you get 13. 78/6=13
So we want x minus 6 to equal thirteen we have to make x a number that will equal 13 when we subtract 6. So we can just add 13+6 to get 19. And 19-6=13. So x=19, does that make sense?
Answer:
2w + 3x ≤ 36
Step-by-step explanation:
Given that :
Hours needed to paint wall = 2 hours
Hours required to frame window = 3 hours
Total hours to spend ≤ 36
Let :
Number of walls to paint = w
Number of windows to frame = x
Hence,
Hours required to paint a wall * number of waas to paint) + (hours required to frame a window * Number of windows to frame.)
(2*w) + (3*x) ≤ 36
2w + 3x ≤ 36
Answer:
30 Chocolate covered raisins will be in each bag and 5 will be left over.
Step-by-step explanation:
In order to solve this, you must divide the number of Chocolate covered raisins by the number of bags you are making. 185 divided by 6 is 30 with 5 left over.
