Answer:
Option D.
Step-by-step explanation:
It is given that a satellite is composed of 30 modular units. Each unit contains the same number of non-upgraded sensors.
Let x be the total number of upgraded sensors on the entire satellite.
The number of non-upgraded sensors on one unit is 1/5 the total number of upgraded sensors on the entire satellite.
Non-upgraded sensors on one unit =
Non-upgraded sensors on 30 unit =
Total number of sensors on the entire satellite is the sum of upgraded and non-upgraded sensors
We need to find the fraction of the sensors on the satellite have been upgraded.
Therefore, the correct option is D.
Answer:
(-1,0)
Step-by-step explanation:
I used a graphing tool to graph the given equations. The lines cross at point (-1,0). Therefore, (-1, 0) is the solution to the system of equations.
1-You subtract 15 from both sides
2-simplify-21-15 to -36
3-Divide both sides by -4
4- two negatives makes a positive so 36/4
Your answer is x>9
