Step-by-step explanation:
k/4=33/20
k=33/20×4
k=33/5
Answer:
The solution set would be all real numbers
Step-by-step explanation:
Remember that you should pass from one side to the other the terms which are similar, that is to say x with x and numbers with numbers. In doing so you must be sure to change the sign of the term if it is passed from one side to the other.
In this case it would be:
4x + 7x + 1 < 11x + 2
(Four plus seven is 11)
11x + 1 < 11x + 2
We can see that x is eliminated, because we change the sign on 11 to be -11:
11x - 11x + 1 < 2
1 < 2
This result means that no matter which value we give to x, the inequality will be always true. For that reason the answer is all real numbers
So what you do first is find the area of this lawn and you do 10 by 12 and multiply those and you get 120 feet so now what you do is divived 120 by 3 and you get 40 so that means she mowed 40 ft in each hour so that would be the unit rate.
Answer:
The rectangle has sides AB, BC, CD, and AD. Then AC and BD are diagonals of the rectangle. The diagonals have the same length.
AC = BD
3x + 15 = 4x - 5
Solve the equation for x.
x = 20
Plug this value of x back into any of the expressions.
