Answer:
x = 20
y = 10
m∡8 = 110°
Step-by-step explanation:
m∡1 + m∡2 = 180
5x + y + 3x + y = 180
8x + 2y = 180
m∡1 = m∡8 (they are alternate-exterior angles and are congruent)
5x + y = 3x + 5y
2x = 4y
x = 2y
Substitute '2y' for 'x' in 8x + 2y = 180
8(2y) + 2y = 180
18y = 180
y = 10
x = 2(10)
x = 20
m∡8 = 3(20) + 5(10) = 110°
Answer:
Step-by-step explanation:
- 3 = 
+ 2x ...... <em>(1)</em>
(1) × 12 :
3x - 36 = 4 + 24x
21x = - 40
x = - 
= 
Final result :
4x3yz2 • (3x - 2y2)

Answer:
480
Step-by-step explanation:
On Thursday there were 400 customers
1/5 of 400 =80
Increase Thursday's amount by 80
400+80 = 480
Friday has 480
