Answer:
a) 30%
b) 280
Step-by-step explanation:
a) 3/10 = 30/100 = 30%

Answer:
57.4g
Step-by-step explanation:
32.8g of sugar is needed to make 4 cakes. How much sugar is needed for 7 cakes?
From the above questions, we know that:
4 cakes = 32.8g
7 cakes = x g
Cross Multiply
4 × xg = 7 × 32.8g
x = 7 × 32.8g/4
x = 57.4 g
Therefore, 57.4g is needed for 7 cakes
Answer:
x^2+4x-32=0
(mid-term breaking---4 x 8=32)
x^2+8x-4x-32=0
x(x+8)-4(x+8)
x+8=0 or x-4=0
So x=+4 or x=-8
