Answer:
70
Step-by-step explanation:
Solve any pre-algebraic equation with inverse operations:
-7 = y/-10
multiply both sides by -10
-7 * -10 = y
now simplify:
remember that multiplying two negatives with result in a positive
70 = y
In order to solve this you need to do the original price - the sold price and figure the difference.
90-180= <span>£</span>18
therefore making it 20% of a profit sale.
4.5 ÷ 3 = 1.5
This means that the ratio has increased by 1.5
Since anything multiplied on one side of a ratio has to be multiplied on the other side too, we multiply 1.5 by 4:
1.5 X 4 = 6
The width would be 6cm
To solve this, you’d multiply 50 by 1.15 to get 57.5 grams of crisps.
Both Coordinates should be negative
