Subtract both sides from 6x, leaving you with the equation:
-2y=-6x+12
Now, you divide all of the sides by -2, therefore leabing you with the equation:
y=3x-6
Answer:

Answer:
65 miles
Step-by-step explanation:
Given:
- k = how many more miles Daniel has to walk
- Goal = 100 miles
- Daily miles = 5 miles
- Number of days already walked = 7 days
Equation:
5 × 7 + k = 100
Solving:
⇒ 5 × 7 + k = 100
⇒ 35 + k = 100
⇒ k = 100 - 35
⇒ k = 65
Answer:
A. 675 units²
Step-by-step explanation:
The formula for the surface area of a square pyramid is ...
A = s(s +2h)
where s is the side length of the base, and h is the slant height of a face.
__
<h3>use the formula</h3>
The given pyramid has s=15 and h=15, so the surface area is ...
A = (15)(15 +2×15) = 15(45) = 675 . . . square units
Decrease = New number - Original Number
% Decrease =
× 100
Decrease = 9 - 12 = -3
% Decrease =
= -0.25 × 100 = -25
Your answer =
-25
