Hello:
x/4 = 28 .... x = 112
x/4 = 30 .... x = 120
x/4 = 32 .... x = 128
x/4 = 34 .... x = 136
x/4 = 36 .... x = 144
the domain is : <span>{112,120,128,136,144}</span>
. Distance = Speed * Time
Let s represent the speed of the cars in miles per hour. The problem statement tells you
.. red car distance + 25 miles = blue car distance
.. s*3 + 25 = s*(3 + 0.5)
.. 25 = 0.5s ... subtract 3s from both sides
.. 50 = s ... multiply by 2
The speed of the red and blue cars is 50 miles per hour.
Answer:
Wayne bought 72 blueberries.
Step-by-step explanation:
To combine the fractions, convert all of the fractions to a denominator of 24.
3/8 * 3/3 = 9/24
1/6 * 4/4 = 4/24
5/12 * 2/2 = 10/24
Now add together the fractions
9/24 + 4/24 + 10/24 = 23/24
He used 23/24 of his blueberries, or 69 of them.
To find the total amount of blueberries, divide 69 by 23, then multiply that number b 24.
69 / 23 = 3
3 * 24 = 72
Wayne bought 72 blueberries.
Answer:
speed = d/t
Step-by-step explanation:
speed = d / t
speed = 72 / 12
speed = 6m/s
