Answer:
Piper's claim is not correct.
Step-by-step explanation:
3(2(-3)+2) = 5(-3)+6
3(-6+2) = -15 + 16
-18 + 6 = 1
-12 = 1
Answer: 68 minutes or 1 hour and 8 minutes spent in all putting up the fence
Step-by-step explanation:
(4/5) x 60 = 48 minutes
4/5 is the same as 0.8, which is what you get when you divide four by 5
So, 0.8 x 60 = 48 is also acceptable
Then,
(1/3) x 60 = 20 minutes
1/3 is the same as 0.333333333333, which is what you get when you divided 1 by 3
So, 0.33333(and so on) x 60 = 20
- Typically, you can round 0.3333333 down to something like 0.333 which should give you a similar answer
Then, as it asks you for how much time he spent in all, you add those two together
48 minutes + 20 minutes = 68 minutes OR 1 hour and 8 minutes (There is sixty minutes in 1 hour, so subtract the 60 from 68 and then you have 8 minutes left, thus 1 hour and 60 minutes)
Number of adults = 264
Number of children= 127
Step-by-step explanation:
Let the number of adults be......x
Let the number of children be.....y
The total number of people that used the public swimming pool is given as 391. This means
x+y=391
The total cost per the receipt is : $752.75
This means, 2.25 x+ 1.25 y = 752.75
The two equations are;
x+y=391 ...........(i)
2.25 x+ 1.25 y = 752.75...........(ii)
Making the x variable equal to eliminate x
2.25x + 2.25 y = 879.75
2.25x + 1.25 y = 752.75
Apply subtraction as
1.00 y = 127.00
y=127
Use the value of y in equation (i)
x+y=391
x+127=391
x=391-127=264
Number of adults = 264
Number of children= 127
