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
x
+
10
(
x
+
0.20
)
=
9.20
10
x
+
10
x
=
9.20
−
2
x
=
7.20
20
x
=
0.36
Thus, the old price was
$
0.36
per liter.
2.20 is your answer
lol yay
Answer:
y= 1x - 1
Step-by-step explanation:
Slope-intercept form: y=mx + b
(-4,-5) (5,4)
m= (y2 - y1)/(x2 - x1) = (4+5)/(5+4)=1
4=1(5)+b
4=5 + b 4-5=b b= -1
y= 1x - 1
Answer:
MKL = 36°
Step-by-step explanation:
(3x + 6) + (6x + 12) = 54°
3x + 6x + 6 + 12 = 54
9x + 18 = 54
9x = 54 - 18
9x = 36
x = 36/9
x = 4
MKL = 6x + 12
MKL = 6(4) + 12
MKL = 24 + 12
MKL = 36°
