Deena said that she received a 25 dollar discount but the equation says 9x + 25 = 28.
The Rewrite would be: 9x - 25 = 28.
How to make the situation fit the equation?: "I bought some shirts at the store for $9 each and received a $25 add on. My total bill was $88. How many shirts did I buy?"
Answer:
$120
Step-by-step explanation:
100x30=3000
4x30=120
27/2=13.5(radius)
area: pi*r*r=
pi*13.5*13.5=
572.55526
rounded, 572.56
circumference: 2*pi*r(which is basically diameter times pi)
27pi=84.823
rounded, 84.82
We know that
<span>1. The number of all 4-letter words written using the alphabet of 20 symbols (from A to T) is
20</span><span>^4=160,000
</span><span>
2. The number of all 4-letter words written using the alphabet of 19 symbols (from B to T) is
19</span><span>^4=130,321
</span><span>
3. The difference represents exactly the number of all words of the inhabitants of the island of Jumble
difference=</span>(160,000-130,321)= 29679.
the answer is
29679
The answer is A. for this, you have to set up a system of equations. the first one will be the area equation. since you know area=length x width, your equation will be LxW=50. the next equation is L=2W, since the length is two times the width. then, plug in 2W for the L in the other equation and you get 2W^2=50. divide by 2 and get W^2=25. square root both sides and you get W=5. plug back into the other equation to find L=10. Then, add the sides of the rectangle for the perimeter. 10+5+10+5=30.
