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

Answer:
$525
Step-by-step explanation:
Edgar Anderson earns in a week = $300
He also earns commission on the sales he makes after his first $1,000 = 15%
Mr. Anderson's sales for one week are = $2,500
His commission is on his sale = 2,500 - 1,000 = 1,500
He earns commission = 15% of 1,500
= 0.15 × 1,500
= $225
His gross pay for that week = $225 + $300 = $525
Mr. Anderson's gross pay for that week is $525.
The volume of a hemisphere is .
What is volume of a hemisphere?
A hemisphere is half of a full sphere, we can calculate the volume of a hemisphere just by halving the volume of the complete sphere.
So, we can calculate the volume of a hemisphere by using the following formula,
Here, is the radius, is the volume of hemisphere.
So,
It is given that the radius is .
We have to find .
So,
Hence, the volume of hemisphere is .

Answer:
volume of hemisphere =1912.26cm^3
Step-by-step explanation:
radius(r)=9.7cm
now volume of hemisphere=(2/3)π
=(2/3)*(22/7)*(9.7)^3
=(2/3)*(22/7)*912.673
=(2/3)*2868.40086
=1912.26cm^3
