Step-by-step explanation:
Simplifying
-4v + 2v = -12
Combine like terms: -4v + 2v = -2v
-2v = -12
Solving
-2v = -12
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Divide each side by '-2'.
v = 6
Simplifying
v = 6
Ok
it might be easier to conver from yards to inches then flip it
1cubic yard=1yard times 1yard times 1yard
1yard=36 inches
1 cubic yard=36 inches times 36 inches times 36 inches
1 cubic yard=46656 cubic inches
divide both sides by 46656
1 cubic inch=1/46656 cubic yards
Answer:
$8
Step-by-step explanation:
Let x represent the amount of money he has to save each week.
We can use this to set up an equation:
Now, we have to "isolate the variable". This means we must have a resulting equation of 
.
In this case, we can use the Division Property of Equality to divide both sides by 7:
Therefore he must say $8 each week for 7 weeks so that he can buy the guitar.
Answer:
15.7 cm
Step-by-step explanation:
The length (s) of an arc of a circle of radius r with a central angle of θ radians is ...
s = rθ
Here, the radius is given as 7.9 cm, and the arc of interest is the supplement of 66.4°, so is ...
θ = π·(1 - 66.4/180) ≈ 1.9827 . . . . radians
Then the arc length is ...
s = (7.9 cm)·(1.9827) ≈ 15.7 cm
