Answer:
(69)(3)−8 = 15
199≠15
False

207 - 8 = 199
x3 - 8 = 199 for x = 69

Arrange the following measurements in order from smallest to largest
4.1 liters, 0.7 liters and 2,000 millimeters
Answer:
first we change 2000mm into litres and I think 1000 mm is equals to 1 L then you look at the first digit and in the first number we have for as the first digit the second number 0 the third number two so in this case 0.7 l is the smallest then 2000mm then 4.1 letters
The measurements in order from smallest to largest is,
0.7 liters, 2,000 millimeters, 4.1 liters
Here,
Given measurements are, 4.1 liters, 0.7 liters and 2,000 millimeters
We have to arrange in order from smallest to largest.
What is Measurements?
The process of associating numbers with physical quantities and phenomena is called Measurements.
Now,
1 liters = 1,000 millimeters
Hence, 2,000 millimeters = 2,000/1,000 = 2 liters
So,
The measurements in order from smallest to largest is,
⇒ 0.7 liters, 2 liters, 4.1 liters
⇒ 0.7 liters, 2,000 millimeters, 4.1 liters

Step-by-step explanation: Set up the equation so that their distances will be equal at some time, x.
Distance = speed × time
3x + 15 = 4x . Subtract 3x from both sides
15 = 4x-3x
15 = x The time is 15 seconds.
At that point their distances will be equal at 60 feet.
