What was gabriel error

Mathematics
1 answer:
Pavlova-9 [17]2 years ago

The change is given by the difference between how much you paid and how much you actually had to pay. For example, if you pay with a $50 bill and you had to pay $13, your change will be 50-13 = 37 dollars.

In this case, we have

30 - (2.5x+2y-2) = 30-2.5x-2y+2 = 32-2.5x-2y

So, Gabriel's mistake was to leave the negative sign to the "-2" at the end of the expression, instead of flipping it to positive "+2" when subtracting it.

Effectus [21]

Answer:

1/12 of the container of milk will be left in the container

Step-by-step explanation:

To solve the question, we first note the variables

Volume of milk available = 9/12 of a container

Volume of milk poured in a pan = 2/3 of a container

Quantity of milk left = Initial quantity of milk less the quantity poured out

That is 9/12-2/3 = 1/12 of the container of milk

This means that there will be only 1/12 of the container of milk left

Simplify the following 3√28-5√63+4√112
alexandr402 [8]

7√7

using the ' rule of radicals '

• √a × √b ⇔ √ab

simplifying the radicals

√28 = √(4 × 7 ) = √4 × √7 = 2√7

√63 = √(9 × 7) =√9 × √7 = 3√7

√112 = √(16 × 7 ) = √16 × √7 = 4√7

substituting into the expression

3(2√7) - 5(3√7) + 4(4√7) = 6√7 - 15√7 + 16√7 = 7√7
