Answer:
a) y = 9.95(x-3) + 20.00
b) Cost of 5 software packages = $39.90
Step-by-step explanation:
Given that:
Cost of 3 software at sale = $20
Cost of regular = $9.95
Let,
x be the number of software purchased.
We will subtract 3 from x because they cost $20.
y be the total cost.
y = 9.95(x-3)+ 20.00
Putting x=5 in expression
y = 9.95(5-3) + 20.00
y = 2(9.95) + 20.00
y = 19.90 + 20.00
y = $39.90
Hence,
a) y = 9.95(x-3) + 20.00
b) Cost of 5 software packages = $39.90
Answer:
The <u>correct answer</u> would most likly be C. Triangle JKL is similar to triangle RST.
Step-by-step explanation:
In the question, we see that triangles JKL and RST have the same slope at lines JL and RT. <u>Triangles with equal slopes are not necessarily congruent; however, it means that they are similar.</u> Therefore , Triangles JKL and RST are similar
Thanks Have a good day!
Hey there!
1. 5(s-2) This is because s-2 is the length of each side, and there are 5 sides in a pentagon all of that length, so multiplying it by 5 like this shows its perimeter.
2. 5s-10 This can be found by distributing the first equation, multiplying both s and -2 by 5.
3. (s-2) + (s-2) + (s-2) + (s-2) + (s-2) Each grouping in the parenthesis represents each of the 5 sides, so adding them all together will get you the perimeter.
4. 5(s) + 5(-2) This one is most like the first one, except it's a little more spread out. Multiply the term s by the 5 sides in one grouping, and the integer -2 by 5 in the other.
Hope this helps!
Answer:
$4.75
Step-by-step explanation:
As the price per pound is a one-to-one ratio, one could just simply multiply by using: 0.7 lbs * ($6.79 / 1 lb) = $4.75/1 = $4.75
