m = money earned in one week
h = hours worked
x = times credit card was swiped
m = 14.45h + 8.50x
If you go to sc and slide to filter you’ll find one that solves the problem
7/8 = x/48
Perform cross multiplication:
a/b = c/d
ad = bc
a = 7 ; b = 8 ; c = x ; d = 48
7*48 = 8x
336 = 8x
336/8 = x
42 = x
7/8 = 42/48
42 ÷ 6 = 7
48 ÷ 6 = 8
Answer:
x = 20
Step-by-step explanation:
7x° + (x + 20)° = 180° (linear pair)
Solve for x
7x + x + 20 = 180
Add like terms
8x + 20 = 180
8x + 20 - 20 = 180 - 20
8x = 160
8x/8 = 160/8
x = 20
