Answer:
Step-by-step explanation:
It's arithmetic.
Just keep on adding 8 to each term.
-3 + 8 = 5
5 + 8 = 13
13 + 8 = 21
Answer:
1. Yes the parentheses are necessary. To find a fourth of her regular hours you must find the total amount she works during her regular hours.
2. 6
Step-by-step explanation:
(For the second question)
4+8= 12
12 × ½ = 12 ÷ 2
12÷2 = 6
<span>8 minutes 20 seconds.
First, lets determine who many miles per minute each vehicle moves by dividing each speed by 60.
Speeder = 60 / 60 = 1 mile per minute.
Police = 75 / 60 = 1.25 miles per minute.
Other car = 45 / 60 = 0.75 miles per minute.
Since the speeding car moves for 5 minutes before the police start to chase, that means that the speeding car will now be 5 + T miles down the road with T being the time the police has been chasing. The police will be 1.25 T. We're looking for when those two equations equal each other. So
5 + T = 1.25 T
Subtract T from both sides
5 = 0.25T
Divide both sides by 0.25
20 = T
So it will take the police officer 20 minutes to catch up to the speeder. And they will both have traveled a total distance of 25 miles from the point where the speeder passed the police car.
Now we need to figure out how far the law obeying car has moved during those 25 minutes. So
25 * 0.75 = 18.75 miles.
The distance the law obeying car needs to travel to catch up to the police officer then becomes
25 - 18.75 = 6.25 miles.
The number of minutes that the law obeying car needs to travel that distance is
6.25 / 0.75 = 8.333....
Which is 8 minutes 20 seconds.</span>

Proportions vs. Percent Equations Two Sides of the Same Coin POD Remember that a proportion deals with the equality of two ratios. Now YOU try it. What is a percent equation? In class problems: Define Percent Equation using p. 456 of your textbook Take a look at this proportion: 12 8 2x+12 24 = Can the 12 and 24 cancel?
<span>Explain. (zoom back out to see the proportion if needed) Is there another way to simplify this problem before cross multiplying? complete with you neighbor and turn in ONE sheet together!
