The answer is 6.
3(4)-5=7 (12-5=7)
6(7)=42
42-9(4)=6. (42-36=6)
Answer:
y = 12x-3
Step-by-step explanation:
X = (y + 3) / 12
Multiply each side by 12 to clear the fraction
12 x = (y+3)/12 *12
12x = y+3
Subtract 3 from each side
12x -3 = y+3-3
12x-3 =y
There's two ways to do this.
The first way:
Work out the amount of sugar needed to make one cake, and then multiply that by 7.
30 grams ÷ 4 cakes = 7.5 grams for 1 cake.
7.5 grams × 7 cakes = 52.5 grams for 7 cakes.
The second way:
Work out the ratio of sugar:cake by doing 7 ÷ 4, and then multiplying that value by 30.
7 cakes ÷ 4 cakes = 1.75
1.75 × 30 grams = 52.5 grams for 7 cakes.
Either way, the answer is 52.5 grams.
