The second answer which is b the answer is 10 all you do is combine like terms then plug it in and do the next step ill reply when i get the second one
I think c .. I already took a course .. and the test had that question.. I cant remember the answer though
Answer:
$30, $75, $45
Step-by-step explanation:
We can set up an equation, where x is an unknown value:
2x+5x+3x=150
10x = 150
x=15
Now that we know what x is, we can plug x in to solve for 2x, 5x, and 3x:
2x=2*15=30
5x=5*15=75
3x=3*15=45
Therefore, the answer is $30, $75, $45
5 no mater what on first hour so, then on the second hour the 1.75 rate kicks in so therefor when x=1, then y=5 so y=5+0 times 1.75
so y=5+1.75 times (x-1)
the naswe ris
y=1.75(x-1)+5 or d
