Answer:
112.5 mL
Step-by-step explanation:
Let x represent the amount of grape juice to add. Then the total amount of grape juice in the mix is ...
0.15(1800) +x = 0.20(1800+x)
270 +x = 360 + 0.2x . . . . . . eliminate parentheses
0.8x = 90 . . . . . . . . . . . . . . . subtract 270+0.2x
x = 90/0.8 = 112.5 . . . . . . . . divide by the coefficient of x
112 mL of grape juice should be added to make a mix that is 20% grape juice.
Answer:
C
Step-by-step explanation:
The graph has a x - axis of amount of scarves in intervals of 1 and a y - axis of hours in intervals of 20
Using this information we can see that in the ordered pair, 1 represents x and 16 represents y, which means that the scarves ar 1 and the hours are 16 in the ordered pair
C makes the most logical sense because there is nothing about centimeters in the graph and the scarves are not in the y, but rather in the x

Answer:
6
Step-by-step explanation:
We can use ratios to solve
15 ft 18ft
---------- = -----------
5ft x
Using cross products
15x = 5*18
15x = 90
Divide by 15
15x/15 = 90/15
x =6
