Answer:
$9.25
Step-by-step explanation:
2.75+ .5(13)
.50 (13)= 6.5
6.5 +2.75= 9.25
Plug in for x.
7(2y - 4) + 5y = -66
14y - 28 + 5y = -66
19y - 28 = -66
19y = -38
y = -2
Put it back into the equation.
2(-2) - 4 = -8
x = -8
The x-value is x = -8
Answer:
x = 90
y = 50
Arc LM = 100
Step-by-step explanation:
Arc MK = 180 degrees
<x = 1/2 Arc MK
<x = 90 degrees
<x + <y + 40 = 180 all angles in a triangle add to 180
90 + <y + 40 = 180
130 + < y = 180
Subtract 130 from each side
< y = 50
Arc LM
1/2 Arc Lm = <y
1/2 Arc LM = 50
Multiply by 2
Arc LM = 100
