$60 + (60 · 0.20) = 60 + 12 = 72
$72 - (72 · 0.20) = 72 - 14.4 = 57.6
Answer: $57.60
Answer:
<A =21
<B = 84
<c = 75
Step-by-step explanation:
<A =x
<B = 4x
<C =5x-30
The sum of A+B+C = 180
x+ 4x + 5x-30 = 180
Combine like terms
10x -30 = 180
Add 30 to each side
10x-30+30 = 180+30
10x = 210
Divide by 10
10x/10 = 210/10
x= 21
Since x =21 we can find the value of the angles
Substituting x into the equations for angles A, B and C
<A =21
<B = 4x = 4*21 = 84
<C = 5x-30 = 5*21-30 = 105-30 = 75
A)y=-6x+4
Slope and intercept a=-6 b=4
equation for new line:
y=cx+d
If new line is parallel c=a=-6 so
y=-6x+d
We substitude point (2,10)
10=-6*2+d /+12
d=22
so y=-6x+22
b)
y=-
x-5
a=-2/3
b=-5
new line:
y=ex+f
If line is perpendicular e=-
so e=
we can write
y=
Substituting point (6,3)
3=
f=3-9
f=-6
y=
Step-by-step explanation:
- -x=y
2.4-y=x
