Let x = the number of songs you can buy.
If you use company A at 0.79 dollars per song, your variable is 0.79x. If you use company B at 0.99 dollars per song, your variable is 0.99x. You are going to set both equal to 30.
Company A: 0.79x = 30
Company B: 0.99x = 30
When solving (though I know you didn't ask), do note that you cannot buy part of a song so you would need to round down to the nearest whole number.
So if you use company A, you divide both sides by 0.79 to isolate the variable x and satisfy the division principle of equality:
x = 30/0.79.
Simplify and your answer is 37.97, round down to 37 songs; you'd have 37 songs with company A and 77 cents left over in your account just sitting there because what really can you do with 77 cents on the App Store?
Answer:
x^4 + 7x^3 + 12x^2
Simplifying
x4 + 7x3 + 12x2
Reorder the terms:
12x2 + 7x3 + x4
Factor out the Greatest Common Factor (GCF), 'x2'.
x2(12 + 7x + x2)
Factor a trinomial.
x2((4 + x)(3 + x))
Final result:
x2(4 + x)(3 + x)
Step-by-step explanation:
20 Days. The least common factor of 4 and 10 is 20 so that is how many days it takes for him to clean both on the same day.
Given:
Cost of each shirt = $14.95
Cost of a tie = $12
Discount on Sale = 15% off
Manny buys three shirts and a tie.
To find:
The Manny's total cost.
Solution:
We have,
Cost of 1 shirt = $14.95
Cost of 3 shirt = 3 × $14.95
= $44.85
Cost of a tie = $12
Total cost before discount = Cost of 3 shirt + Cost of a tie
= $44.85 + $12
= $56.85
Everything in the store is on sale for 15% off. So,
Therefore, the Manny's total cost is $48.3225.
Answer:
first of all,
Step-by-step explanation:
In triangle ABC one side equal and two sides equal
Step-by-step explanation:
We are given a prism whose base is square with sides 8 in and height 12 in.
If we take cross section through vertices A, B and C
We will get a cross section as triangle.
In triangle ABC, sides are AB, BC and AC
AB is diagonal of top square whose side 8 in.
AC is face diagonal of front face.
BC is face diagonal of right face.
AC=BC≠AB
Hence, In triangle ABC one side equal and two side equal
Hope this helps!!
