Answer:
<em>A) Points earned = 15 - 6</em>
<em>B) Sandy didn't make it to the next level since her score was 9 and she needed a minimum of 10</em>
Step-by-step explanation:
To advance to the next level in her game, Sandy must score at least 10 points.
She scores 15 points for correct matches
She scores -6 points for incorrect matches.
A. The amount of points earned by Sandy in the game is the sum of both scores:
points earned = 15 - 6
points earned = 9
B. Unfortunately, Sandy didn't make it to the next level since her score was 9 and she needed a minimum of 10
The algebraic expression of the statement is 4x + 6
<h3>How to determine the
algebraic expression?</h3>
The statement is given as:
The sum of four times a number and six
Rewrite as:
The sum of 4 times a number and 6
Let the number be x
So, we have
The sum of 4 times x and 6
Evaluate the product
The sum of 4x and 6
Evaluate the sum
4x + 6
Hence, the algebraic expression of the statement is 4x + 6

The volume of a rectangular prism is given by
area of base × height
The rate at which the tank is being filled is 1 liter per minute which we need to convert
1 liter = 1 dm³
But 1 dm = 10 cm. Hence
1 liter = (10 cm)³ = 1000 cm³
The height h of the water is related to the volume by
volume = area of base × h
In one minute the volume increases by 1 liter or 1000 cm³ and the height increases by
h = volume / area of base = 1000 cm³ / 100 cm² = 10 cm <span>
