The answer is D.$12.15
5(1.29)+10(1.49)+2(1.25)+4(6.00) =$47.85
$60-$47.85 = $12.15
Answer:
3m+4 & m+4+2m
Step-by-step explanation:
substitute m=1
3(1)+4 and (1)+4+2(1)
4+3=7 5+2=7
substitute m=4
3(4)+4 4+4+2(4)
12+4=16 8+8=16
The exterior angle equals the sum of two interior opposite angles
x + 90 = 2x + 40
Sum of all interior angles = 180
x + 90 + (x - 10) = 180
Answers:
x + 90 + (x - 10) = 180
x + 90 = 2x + 40
