ANSWER
The value of x is

EXPLANATION
We want to solve the equation,

The first step is to add 4 to both sides of the equation to obtain,

We simplify the right hand side to obtain,

We now square both sides of the equation to obtain,

This simplifies to

We solve for x to obtain,

This implies that,
It’s B. Dan is 124 miles from home at noon and is traveling at 62 miles per hour
First, you need to do the distubutive property, you should get 18m+30=66. Then you could subtract 30 from both sides. Then, you should get 18m = 36. You will then divide both sides by 18. Your answer should be m = 2. Hope this helps!
Answer:
a < 3
n < 3
Step-by-step explanation:
We will solve each inequality one by one.
Solve first inequality :
3a - 4 < 5
add 4 both the side
3a < 9
divide 3 both the side
a < 3
Solve second inequality:

subtract 5 both the side

now multiply by -3 both the side and reverse the inequality sign
n < (-3)*(-1)
n < 3
That's the final answer. I hope it will help you.
