Answer:
42 gallons 45% antifreeze
28 gallons 95% antifreeze
Step-by-step explanation:
If x is volume of 45% antifreeze, and y is volume of 95% antifreeze, then the total volume is:
x + y = 70
And the total amount of antifreeze is:
0.45 x + 0.95 y = 0.65 (70)
Solving by substitution:
0.45 x + 0.95 (70 − x) = 0.65 (70)
0.45 x + 66.5 − 0.95 x = 45.5
21 = 0.5 x
x = 42
y = 28
Step-by-step explanation:
2 × (First Angle + Second Angle) = 360°
5x + 9x + 26 = 360°/2
14x + 26 = 180°
14x = 180 - 26
14x = 154
x = 154/14
x = 11°
The answer is B.
Answer:
answer is A
Step-by-step explanation:
Answer and Step-by-step explanation:
First, plot the y-intercept. This is (0, -8)
So, go down -8 units from the origin (0,0).
Now, go down 3 and right 1 units from -8, until you reach the bottom. Do the same thing from -8 but up 3 and left 1 unit.
This is what it should look like:

The best way is to use the number 3 because they would have a equal amount of kids in each group..10×3=30
