Answer:
Daniel must tutor 160 hours
Explanation:
310+275+70= 655
655×6= 3930 (he needs this amount of $)
(Daniel gains $20 per hour)
20×160= 3200
3200+745= 3945
3945 > 3930
Daniel has enough for the trip.
Where did I get 160?
Well, I was just trying out numbers and multiplying it by 20
The numbers I tried: 100, 150, 156, 159 & 160 but only 160 fit with the answer.
If it was just one night road trip he would've just needed $655, but since it's a 6-night road trip I multiplied it by 6.
Hope this helped!
The value of x is about 4.7
Answer: x = 2/3 and y = 2/3
Step-by-step explanation:
I've attached the solution.
From the solution, you get y = -5x + 4 and
y = x.
Now,
Put y = x in y = -5x + 4.
x = -5x + 4
6x = 4
x = 4/6
x = 2/3
So, y = 2/3 because y = x.
