I guess you want to find the average speed for the whole journey
average speed = distance travelled / time
the distance from home to the shop = speed * time = 0.5*10 = 5 miles
time for travelling back = distance / speed = 5/30 = 1/6 hours
average speed for whole journey = 10 / (1/2 + 1/6) = 10 * 3 / 2 = 15 mph
Answer:
Step-by-step explanation:
<em>Hey there!</em>

Well to solve for x in,
16x - 7 ≤ -71
We need to single out x.
16x - 7 ≤ -71
+7 to both sides
16x ≤ -64
Divide both sides by 16
x ≤ -4
<em>Hope this helps :)</em>
If you solve it, the answer will be
C= 4.80
Seeing as its supposed to be a whole number, you will round up, so it will be 5
Answer:
|h-13| ≤ 2
Step-by-step explanation:
The difference between the height of the plant (h) and show size (13 in) can be written as ...
h - 13
This value is allowed to be positive or negative, but its absolute value must not exceed 2 inches. Thus, the desired inequality is ...
|h -13| ≤ 2
