Answer for #1
Let the old price be
$
x
per liter. 10 liters would have cost a total of
$
10
x
.
The new price is
$
(
x
+
0.20
)
per liter. 10 liters would have cost
$
10
(
x
+
0.20
)
.
The total cost is
$
9.20
. So,
10

+
10
(
x

0.20
)
=
9.20
10

20
x
=
0.36
Thus, the old price was

Answer:
w = 15
Step-by-step explanation:
We have an expression and are asked to solve for w.
-19w + 11 = -17w - 19
Subtract 11 from both sides :
-19w = -17w - 30
Add 17w to both sides :
-2w = -30
Divide -2 from both sides to isolate w :
w = 15
Answer:
so
Step-by-step explanation:
We know that Quinton struck out 12 batters, 5 batters, and 8 batters. Key word: in all. In all means addition. So, 12 + 5= 17, and 17 + 8= 25. 25 batters.
2+3.25g=y
G would be the independent variable, which means the total cost would depend on it since it depends on the number of games you bowl. Y could be any variable, such as T or C.
2+3.25g=y
