Step-by-step explanation:
4x -20 + 3x +12 = 90
7x -8 = 90
7x = 98
x = 14
Angle F: 4(14) -20 = 36
Angle E: 3(14)+12= 54
Angle G : 90
Answer:
17. is 20 18. is 9hours 19. is 60mph
you get this by doing 100 divided by 5 which equals 20 360 divided by 40=9 and 420 divided by 7 =60
3 boxes of computer diskettes at $8.99 per box = (3 * 8.99 = 26.97 )
2 packages of pens at $ 2.50 per package = (2 * 2.50 = 5.00 )
6 boxes of paper at $ 22.95 per box = (6 * 22.95 = 137.70)
1 printer ribbon at $25 each. = (1 * 25 = 25)
Add up (26.97+5.00+137.70+25 ) and the answer is = 194.67
