Answer:
Option (d) is wrong.
Step-by-step explanation:
Slope is:
- rise over run
- The rate of change of a line
- Change in y over the change in x
- <em><u>The ratio of vertical change to the horizontal change. </u></em>
It can be given by mathematically as follows :

Hence, the option which is not a description of slope is (d) "the ratio of horizontal change compared to vertical change"
Perimeter is the sum of all sides in the figure. Here, all six sides are equal in length so it would be:
p = 6 * side
p = 6 * 3.9
p = 23.4 cm
In short, Your Answer would be: 23.4 cm
Hope this helps!
Jace bought 4 cookies and 2 brownies from the bakery.
Let x represent the number of cookies and y represent the number of brownies.
Since he bought $9 worth of cookies and brownies. Each cookie costs $0.75 and each brownie costs $3. hence:
0.75x + 3y = 9 (1)
Also, he bought twice as many cookies as brownies, hence:
x = 2y
x - 2y = 0 (2)
Solving equation 1 and 2 simultaneously gives x = 4, y = 2
Hence Jace bought 4 cookies and 2 brownies from the bakery.
