Plug in </span><span>y=5::
4x+7(5)=51
Simplify:

</span>
<span>4x+35-35=51-35

The completion of the table showing the different percentages of the days that Kimmimela and her foster brother fed the rabbits this year is as follows:
<h3>Rabbit Feeding Table:</h3>
Person Time (days) Percentage
Kimimela 350 95.9%
Foster Brother 15 4.1%
<h3>What is a percentage?</h3>
A percentage is a mathematical expression of a number or ratio as a fraction of 100.
A percentage is often denoted with the percent sign, "%."
Most importantly, a percentage shows the relative value of a variable out of the hundredth parts of the class.
For instance, this question showed that Kimimela fed her rabbits 350 out of 365 days of this year. This implies that her foster brother fed the rabbits for 15 days (365 - 350).
<h3>Data and Calculations:</h3>
Person Time (days) Percentage
Kimimela 350 95.9% (350/365 x 100)
Foster Brother 15 4.1% (15/365 x 100)
Total 365 100%
Thus, we can conclude that Kimimela fed the rabbits <u>96%</u> of the days.

The area of a parallelogram is
A= bh
where
A = area
b = base
h = height
Any side of a parallelogram can be used as the base. The height of a parallelogram is a perpendicular line from the base to the opposite side of the parallelogram. If needed, you can replace the opposite line segment with a line that overlays the line segment and continues to infinity in both directions.
Given the 4 points, the line segments (4,1) to (10,1) and (8,-4) to (2,-4) are the most interesting. Both of those lines have a slope of 0, which makes finding the distance between those two lines trivial. The height is simply the difference in their y-coordinate values. So
h = 1 - (-4) = 1 + 4 = 5
And the length of the base is the difference between their x-coordinates. (You can use either line for the base). So
b = 10 - 4 = 6
So the area is
A = bh
A = 6 * 5
A = 30</span>
Answer:
70 decreased by 20% = 56
Absolute change (actual difference):
56 - 70 = - 14
Step-by-step explanation:
<span>If dog food costs $2 a pound and Cara buys 9 pounds, her expenditure on dog food is 9 x 2. This makes $18. If she has a total budget of $25 and spends $18 on dog food, she has $7 left over for treats (25 - 18 = 7). At $1 each, she can buy up to 7 treats.</span>
