Answer:
b.7
Step-by-step explanation:
you take the three and substitute that in for x. 2(3) + 1
2(3)=6 then add 1
1 3/7 ~ One and three sevenths
Answer:

Step-by-step explanation:
Given equation :

Making the terms of 'x' to one side and constants to the other.






So, the value of 'x' is 29.
Given:
- The product of two numbers is (-9/16).
- One of the numbers is (-4/15)
To find: The other number.
Answer:
Let's assume the unknown number to be 'x'.
(-4/15) × x = (-9/16)
× = (-9/16) ÷ (-4/15)
When we divide a fraction by another fraction, the divisor will be taken in its reciprocal form.
x = (-9/16) × (-15/4)
x = 135/64
Therefore, the other number is 135/64.

Let

be the amount of parts the student answered correctly. Suppose that

is a function between

and the score of a student's project. As the student initially receives a fixed

points for turning the project in and

points for each correct part, the function is initially:

When the students receive

points for each correct part, the coefficient of

changes, as the amount of points received per correct answer increases. Thus:

.
