Answer:
2x²+ 7x + 12
Step-by-step explanation:
2x(x+5)-3(x-4)
2x²+ 10x - 3x +12
2x²+ 7x + 12
<u>ANSWER: </u>
The equation is y = 1.06x, so option D is correct.
<u>EXPLANATION:</u>
Given:
Amount Catherine is paid for an MP3 player=$159.00
The price paid includes a sales tax= 6%
To find:
Equations that can be used to determine the price of the MP3 player before tax?
Solution:
Now, we know that, total cost = selling price of item + sales tax on item
y = x + 6% of x
y = x + 
y = x + 0.06x
y = 1.06x
Hence, the equation is y = 1.06x, so option D is correct.
Answer:
Step-by-step explanation:
1/4 of the 300 skiers are beginners......1/4 of the 260 snowboarders are beginners..
so we want the total number of beginners..
the distributive property in this situation would be :
1/4(300 + 260) .......to solve this, u first have to get rid of the parenthesis. To do this, u multiple the number directly to the left of the parenthesis, by everything in the parenthesis.....u distribute it.
1/4(560).....now we multiply
560/4 = 140
OR
this way
1/4( 300 + 260) = 1/4(300) + 1/4(260) = 300/4 + 260/4 = 75 + 65 = 140
The awnser is 27
hope that helps
