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:
(5,10)
(3,6)
Step-by-step explanation:
The equation y=2x means that 2 multiplied by the first value would equal the second value, so this means that the second value is twice as much as the first value. This is not true for the first option because 8 is not twice of 16, and this is the same for (4,6), (4,2), and (1,3). Therefore (5,10) and (3,6) work.
20,000 x 25 = 500,000
500,000 divided by 100 = 5,000 members are lost.
Members left = 15,000
Members added = 10,000
Members every year = Members left + Members added
= 15,000 + 10,000
= 25,000
So k=katie's' age
m=mara's age
k is 2 times as old as m
k=2m
sum is 24
add means sum
k+m=24
so we have
k+m=24 and
k=2m
subsitute
2m+m=24
add
3m=24
divide both sides by 3
m=8
subsitute again
k=2m
k=2(8)
k=16
katie=16
mara=8
Answer: 24
Step-by-step explanation:
You need to find the common denominator. In the case 24 is the least one because when you multiply 3 by 8, you finally have a common denominator for all three.
