Answer:
A=15
B=13??
C=15
D=85
Step-by-step explanation:
B is the only one I'm not sure
Step-by-step explanation:
30=-5(6n+6)
30=-5×6n-5×6
30=-30n-30
30+30=-30n
60=-30n
60/-30=-30n/30
-2=n
Answer:
x=
1/2
Step-by-step explanation:
6x+9=12
Step 1: Subtract 9 from both sides.
6x+9−9=12−9
6x=3
Step 2: Divide both sides by 6.
6x/6=
3
/6
And Your Answer Will Be:
x=
1/2
the line that is parallel will be y = 1/2x
Answer:
Divide both sides by V
Step-by-step explanation:
The equation is not well written.
Mariko needs to solve the equation below for D. Here is the equation:
M = DV
For Mariko to get D, he needs to make D the subject of the formula by dividing both sides of the equation by the coefficient of D i.e V as shown;
Divide both sides by V
M/V = DV/V
V at the denominator will cancel out the V at the numerator to have:
M/V = D
Rearrange
D = M/V
Therefore, the statement which correctly describes the step he should take is:
Divide both sides by V. Option B is correct.
