If a car moves 60ft in 24secs. How far will the car travel in a minute.
To solve this problem we need to find the rate. Since we know that distance=rateXtime. Since we do not know the rate we will have to divide the distance by the time. 60/24 = 2.5 . So this means that the car is moving 2.5 feet per second. Now we take 2.5 and multiply it by 60. Now we know that in a minute the car will travel 150ft/sec.
Describe an absolute number and give an example of how you write and evaluate them.
An absolute number describes how far away the number itself is away from 0. In essence an absolute number is the positive equivalent of the number. The absolute value of -31, which is written as |-31|, is 31.
Solve this problem simplify (x-3)/6 = (x+7)/4
You must begin the problem by cross multiplying. This changes the equation to 4(x-3) = 6(x+7). You must them multiply throughout making it 4x-12=6x+42. Then you must subtract 42 from both sides and also subtract 4x from both sides. The equation now looks like 54=-2x. Finally you must divide by -2 and the solution is x=-27
