Answer:
1. 24 quarts. 2. 85 seconds.
Step-by-step explanation:
1. We need to know how many 2/3 are in 4.
if 3/3 are in 1 cup, then 12/3 are in 4 cups.
there are 6 twos in 12, so there are 6*2/3 cups in 4 cups.
Each 2/3 needs 4 quarts of green, and we have six times that.
6*4 = 24, so we need 24 quarts of green paint.
2. The 12.75 miles would go in the "d" or distance part of the equation.
d = 0.15t
12.75 = 0.15t (divide both sides by 0.15)
12.75/0.15 = 0.15t/0.15
t = 85, so 85 seconds.
12.75 miles isn't the distance between the two cities, it's much farther, so this answer makes sense.
Answer:
D.(-1,-5) and (5,7)
Step-by-step explanation:
I used a graphing tool to graph the two equations together. When graphed, the equations intercept (5,7) and (-1,-5). Therefore, they are the solutions to the system.
Option D should be the correct answer.
Answer:
Step-by-step explanation:
The domain is the x value between - 5 and 7
The range is the y value between -2 and 6
You can find all sorts of definitions for the domain and range, but in this example it is really straight forward. If you put - 5 into the function, you get -2. If you put 7 into the function, you get 6. Now just draw a line between the two end points.
Since it is a horizontal line with both Y's at 3 ( second number inside each set of parenthesis) we know the mid point is (X, 3)
to find the midpoint of X add the 2 values and divide by 2:
-2 + 10 = 8
8 / 2 = 4
so the midpoint is (4,3), the answer is D
