Answer:
a = 7
Step-by-step explanation:
3(1 - 2a) = -3a - 18
3 - 6a = - 3a - 18
Add 18 to each side:
3 + 18 - 6a = - 3a - 18 + 18
21 - 6a = - 3a
Add 6a to each side:
21 - 6a + 6a = - 3a + 6a
21 = 3a
3a = 21
Divide each side by 3:
3a ÷ 3 = 21 ÷ 3
a = 7
Answer:
Step-by-step explanation:
Given the inequality
, we need to solve for "x".
We can subtract
to both sides:

(This step is shown in the exercise)
Now, we can add 10 to both sides:
(This step is not shown in the exercise)
And finally, divide both sides by -3:

(This is shown in the exercise)
Therefore, the missing step is:
Answer:
15 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = (- 1, - 5) and (x₂, y₂ ) = (- 10, 7)
d = 
= 
= 
= 
= 15 units
