Answer is 13-1/2 cups
Step by step
We know 1 cup is = 2/9 of a liter
We know we are working with 3 liters = how many cups
So first I want my 3 liters in a like denominator based fraction
1 liter is = 9/9 so 3 liters is = 27/9
I want to divide 27/9 by 2/9, the part of a liter that equals 1 cup
When I divide a fraction, I flip one fraction and multiply
27/9 x 9/2 = 243/18, simplify to 13-1/2 cups
Problem solved
You can check your work
Multiply 13-1/2 cups x 2/9
Change your whole number to a mixed fraction
27/2 x 2/9 = 54/18, simplify it equals 3 liters!
8+8+8 is that as repeated addition
Let
x-----------> the number of kids
y----------> the number of adults
we know that
2.5x+6y=$7150---------> equation 1
x=2y-------------> equation 2
substitute 2 in 1
2.5*[2y]+6y=7150-----> 5y+6y=7150----> 11y=7150-----> y=650
x=2y----> x=2*650----> 1300
the answer is
the number of kids is 1300
Answer:
The answer to your question is below
Step-by-step explanation:
a) Find to points of the line and find the equation of the line.
A ( 0, -4) B (2, 0)
slope = m = 
m = 2
Line equation
(y - y1) = m (x - x1)
(y - 0) = 2(x - 2)
y = 2x - 4
Write the line as an inequality
y ≥ 2x - 4
b) Yes, (2,0) is a solution of the inequality
y ≥ 2x - 4
0 ≥ 2(2) -4
0 ≥ 4 - 4
0 ≥ 0 This is true
c) No, (4, -2) is not a solution.
y ≥ 2x - 4
-2 ≥ 2(4) - 4
-2 ≥ 8 - 4
-2 ≥ 4 This is false
Answer:
Two angles are called supplementary when their measures add up to 180 degrees.
