If he pays with a £5 note and gets 30p change, that means the total cost was £4.70
All the items prices have to add up to £4.70
£1.18 + 94p = £2.12 so the two jars of jam together must cost £2.58 (£4.70 - £2.12).
If two jars cost £2.58 then one jar must cost half of that: £1.29
One jar = £1.29
Fasle,2nd degree(^2)polynomials are called quadratics, 3rd degree are called cubics
First you divide G on both sides, and since both Gs cancelout you get 1/G=h+2/3. Then subtract 2/3 on both sides so you get h=1/G-2/3
The answer is 29/21. 4/6 + 5/7 = 29/21. so theres your answer
Y=-x+27
Subtract x from both sides to get y by itself
