Answer:
110°
Step-by-step explanation:
5x+10=4x+19
5x-4x =19-10
x = 9
m <em>L</em><em> </em>ADB = 5(9)+10=45+10=55°
so m <em>L</em><em> </em>ADC = 2×55° = 110°
3 x 18 = $54
2 x 3.99 = $7.98
1 x 45.00 = $45.00
Add: $54 + 7.98 + 45 = $106.98
Multiply: $106.98 x 0.085 = 9.093
Add: $106.98 + $ 9.09 = $116.07
He paid $116.07 total.
Answer:
350 tickets
Step-by-step explanation:
if you do 42/350, it would equal 12%, so 350 is the total
Question 1. -3 + v5 = 0
Work : -3 + 5v = 0
5v = 3 ( divide )
answer v = 3/5
Question 2. 1 - 7B = -20
work : -7b = -20 - 1
-7b = -21 ( divide )
answer b = 3
question 3 : -k - 5 = 0
work : -k = 5
answer : k = - 5
Question 4 : -1 + 8a = 129
work : 8a = 129 + 1
8a = 130 (divide )
answer a = 65/4
