If 150g of sugar is used for 5 cakes
How much is used for 7 cakes?:)

Answers

Well, if 150 grams is used for 5 cakes, we can divide that.
150/5=30. 30 grams of sugar are used for each cake
You want to know how many grams for 7 cakes
30x7=210 grams of sugar are used for seven cakes.
Hope this helps!

150 g - 5 cakes
x g - 7 cakes

$x=(7\cdot150)/(5)\nx=210$

The algebraic expression is a difference between two terms will be 5y - 7. Thus, the correct option is A.

What is Algebra?

Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.

An algebraic expression that is created by removing two terms is known as a difference between two terms. Only one of the suggested expressions corresponds to this description:

⇒ 5y - 7

The difference between the terms 5y and 7, which are being subtracted from one another, is represented by this equation.

Thus, the correct option is A.
