Answer:
14,400
Step-by-step explanation:
I'm assuming this is multiplication so it would be 14,400
Supplementary angles add up to 180°
x = greater supplementary angle
x - 118 = lesser angle
x + (x - 118) = 180
2x - 118 = 180
2x = 298
x = 149
x - 118
149 - 118 = 31
the angles are 31° and 149°
£9 - 90p = £8.10
2 Pencils = 48p
3 Pens = £1.11
3 Sharpeners = £2.31
All together = £3.90
£8.10 - £3.90 = £4.20
£4.20 / £1.40 = 3
Answer = 3 Notebooks
2/20 = 1/10 = 3/30 = 4/40
so 3 equivalent ratios can be 1/10 (or 1:10), 3/30 (or 3:30), 4/40 (or 4:40)
