Answer:
45 kg = Bethan's share
105 kg = Jade's share
Step-by-step explanation:
Let 3x = Bethan's share
4x = Noah's share
7x = Jade's share
Since Noah's share was 60, then 4x = 60
x = 15
3(15) = 45 kg = Bethan's share
7(15) = 105 kg = Jade's share
Well you divide the 75 percent and the 18 and you will get your answer
Distribute so times what's outside by what's inside so 4×2x=8x and 4×7=28 then get x by itself by dividing on both sides 28÷8=3.5 your answer is x=3.5
-8.8 is the simplify expression and as well as the exact value
