Answer:
48 liters
Step-by-step explanation:
First container = x
Second container has twice as much oil.
Second container = 2x
13 liters of oil was used from first container.
x - 13
7 liters of oil was used from the second container.
2x - 7
Second container has 3 times more oil than the first one.
2x - 7 = 3(x - 13)
x - 7 = 3(x - 13)
x - 7 = 3x - 39
2x = 32
x = 16
First container = 16 liters
second container = 16 x 2 = 32 liters
Total = 16 + 32 = 48 liters
I believe the answer is the 64 ounce container that is $3.20. the unit price of it was 0.05 while the other one was 0.055
Answer:
3.93700787402, almost 4
Step-by-step explanation:
10 ÷ 2.54
3 × 2.50 = 7.50
3 × 0.04 = 0.12
7.50 + 0.12 = 7.65
7.65 + 2.54 = 10.19
The precise number is use calculator.
Answer:
Between 67 and 103 beats per minute
Step-by-step explanation:
The minimum would be 80. That means that the minimum sum would have to be 320 among the four numbers.
85+81+87=253
320-253=67 so 67 will be the minimum
now, we should see the maximum. It will be 89 so the sum of the four numbers cannot be anymore than 89*4 which is 356
So, 356-253=103
Answer:
(5x+1)(x+4)
Step-by-step explanation:
5*4 = 20
20*1 = 20 and 20+1 = 20
5x^2+20x+1x+4
5x(x+4)1(x+4)
5x+1)(x+4
