Answer:
its a 21:45
Step-by-step explanation: it a because 7x3 will equal 21 you got 21 in there. 15 x 3 will equal 45 and you got 45 there so a is your answer.
There is no solution. Because the absolute value function finds the distance between the number and 0. And length is never negative.
So, |-x| = -10 has no solution.
Regroup terms
Add 2x to both sides
Simplify 4 - x + 2x to 4 + x
subtract 4 from both sides
subtract -6 - 4.
Answer: x = -10
82,300 because you need to round it to the 100 place
no solution, since the graph two parallel lines with no intersect
