One tart =25.20-12.40/16 One tart =80c therefore cake =9.20. Multiply the $9.20 by 5 to get your answer😊

If June is 5kg heavier than the average of her friends, we can say that the total mass is 5units + 5kg ＝ 43kg x 5 1 unit + 1kg ＝ 43kg 1 unit ＝ 42kg Mass of June ＝42kg + 5kg ＝ 47kg.

5x43kg=215kg 215kg-5kg=210kg 210kg/5=42kg Mass of June = 42+5=47kg

Sorry, but you cant assume it is 1/4 of a side of a sqr in figP

I think this would be a better method: Realise that the sum of ALL the horizontal lines in Figure P is equals to the sum of 6 sides of the squares. The sum of ALL the vertical lines in Fig P is equals to sum of length of 6 sides too. Hence, 12 sides ＝ 240cm 1 side ＝ 20cm Now for Fig Q. Notice that the sum of ALL vertical lines is equals to 6 sides, while sum of ALL horizontal sided is equals to 4 sides of a square. Thus, Perimeter of Fig Q ＝ 10 sides ＝10 x 20cm ＝200cm

I mean... how did you know how the squares are put. Maybe the length of the two bottom sides in the middle layer is 1.35cm and 0.65 cm?

After Siti gave away w pears, she had 3w pears left. Take away 1 pear since she ate that, she had (3w - 1) pears left. Her brother ate half of what remained = (3w -1)/2. Hence, she had (3w -1)/2 left
