Step-by-step explanation:
- Mr. Anderson drove 168 miles in 3.5 hours. Distance here is 168 miles.
- He drove for 2.25 at a rate of 5miles/hour. The speed here is 5miles/hour.
Since we are looking for distance, we have to convert the 2nd part (which is the speed) to dostance.
Distance = speed x time
Distance = 5 x 2.25 = 11.25
In the first part, he drove for 3.5 hours. And in the 2nd part, he drove for 2.25 hours which sum up together to be 5.75 hours.
Since we have the distances for both parts now, we just sum it up
which it 168 + 11.25 = 179.25 miles
I hope this is good
Answer:
Step-by-step explanation:
You want to factor the trinomial. What two numbers multiply to equal 1, but add to equal 2? Thats easy, its just 1.
You now have (x + 1) twice, so you can just square it like this:
We can make that term equal to 0 to get x = -1, but remember that this isnt an equation. This is an inequality, so x > -1
In order to graph this, you should shade everything to the right of -1 because we have the greater than sign. Make the circle open because we are not including -1. It is everything greater than -1
Answer:
2/3
Step-by-step explanation:
Divide both the numerator and denominator by the GCD
4 ÷ 2 = 2
6 ÷ 2 = 3
1.99 or 199/100 or 1 99/100
2.25 or 9/4 or 2 1/4
