Answer:
2l + 3 = 39
Step-by-step explanation:
Let l = Lindsay's age in years.
Carol's age is three more than two times Lindsay's age
Carol = 2l+3
Carol = 39
39 = 2l+3
The transformation(s) that can be used to map one triangle onto the other is : (C). dilation, then translation
<h3>Meaning of dilation and translation</h3>
Dilation can be defined as the process of compressing and reducing a shape to a particular scale
Translation can be defined as a process of transferring a shape from one point to another.
In conclusion, The transformation(s) that can be used to map one triangle onto the other is : (C). dilation, then translation

This is a lot of calculation.
So we know that the sum of angles for any heptagon is 900, because heptagon can be divided into five non-overlapping triangles and sum of angles of each triangle is 180.
Now you just add up all angles and simplify the equation:
900 = (6x - 8) + 120 + (7x - 64) + (5x - 4) + 135 + (3x + 31) + (4x + 15)
900 = <span>25x + 225
Now it's just regular algebra equation. You can solve for x:
675 = 25x
x = </span>27
So the value of x is 27

Jamil has already 6 3/4 cups of butter.
He need 12. SO in order to get the needed butter, we subtract 6 3/4 to 12.
= 12 - 6 3/4
= 11 4/4 - 6 3/4
= 5 1/4
So Jamil needs 5 1/4 cups of butter to achieve the 12 cups.
