Although you didn’t list any equations, here is the correct one:
15 + 5x = 25
1.5 twice a day makes it so it’s 3 miles total. Thus, you need to multiply that by 5 to get the total amount in one week.
x will solve for each evening per day.
Hope this helps!
Answer:
h = 6 units
Step-by-step explanation:
The formula for the volume of a tetrahedron is given as :
V = sh
Where
s is area of base and h is height
Put s = 8 and V = 48 to find h as follows :

So, the height of the tetrahedron is 6 units.
Answer:
b=a √3
Step-by-step explanation:
Since you are given the area, we can solve for radius with this equation:


The radius is 11, so the diameter must be 2 times that, which is 22. With the correct units, the answer is
22 units²
(21 + 34 + x + 25 + 37 + 22) / 6 = 30
(139 + x) / 6 = 30 .....multiply both sides by 6
139 + x = 30 * 6
139 + x = 180
x = 180 - 139
x = 41......so during week 3, she rode her bike 41 miles
