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!
Answer:
X=25
Step-by-step explanation:
Remove parentheses
7x - 5x - 40= 10
Merge the similar terms
2x - 40= 10
Constantly move to the right side and change characters
2x = 10 + 40
Addition
2x = 50
Divide both sides of the equation by 2
x = 25
