For this case we have the following functions:
Equalizing we have:
To solve we factorize, that is, we look for two numbers that when multiplied give a result of 4 and when added together give a result of -4. These numbers are -2 and -2.
Thus, we have:
So, the solution is
Answer:
Answer:
21
Step-by-step explanation:
Since there are 7 days in a week, we'll multiply 3 by 7, resulting in an answer of: 21.

I will do a and b and you do the rest.
For (a), the equation is x + y = 154.
For (b), the equation is 320x + 85y = 14,970.
We have two equations in two unknowns.
Use the substitute method to find x and y (the given c). Once you have x and y, use that to find d.
Take it from here.
Answer:
x is approximately 25.83
Step-by-step explanation:
x + 25 + 5x = 180
6x + 25 = 180
6x = 155
x=25.83
