the negatives cancel out :)
Answer:
If you subtract -2x+y=0 and -7x+3y=2 you will get 5x-2y=-2
Step-by-step explanation:
Subtract -2x and -7x which is 5x
Subtract y and 3y which is -2y
Subtract 0 and 2 which is -2
Result: 5x-2y=-2
Hope this helps!
From the looks of it, each one is multiplied by -2, so it will be
-4,8,-16,32,-64,128,-256
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.
