Answer:
x = -3; substitute it to the other equation.
2(-3) - 7y = 30
-6 - 7y = 30
-7y = 30 + 6
-7y = 36
y = -36/7
we will not round the number because the question is asking for an improper fraction at its simplest form.
Answer:
250 - 20 < 80 + 15x
Step-by-step explanation:
Given that
Beth has 250 books and 20 books sold each week
While on the other hand, Martin has 80 books and sell 15 books each week
Let us assume each week be x
Now the equations are
Beth 250 - 20x
Martin 80 + 15 x
Now the inequality would be
250 - 20 < 80 + 15x
Answer:
Minimum hour = 177 hour
Step-by-step explanation:
Given:
Paddle boats rent = $8
Paddles rent = $5 Per 24 hours
Total amount = $45
Find:
Number of hour David rent paddle boat
Computation:
8 + (5/24)n = 45
(5/24)n = 37
n = 177.6 hour
Minimum hour = 177 hour
Answer:
Month 5 is when it will be at $100
I hope this helps!
Step-by-step explanation:
x---0-----1-----2-----3----4-----5
y-300-260-220-180-140-100
y=40x+300
So I’m guessing 40 is x so if 40 is the hours u put 290=40(3)+50 so then it would be 290=120+50 then it would simplify even more to 170 then 290-170=120 and 120 is ur answer I hope I’m right
