Answer: $255
Step-by-step explanation:
A store advertises 15% off an item which sells for $300. The sale item will then be calculated as:
= $300 - (15% × $300)
= $300 - (0.15 × $300)
= $300 - $45
= $255
The sales price is $255.
A 15% discount is similar to a 15% decrease because in both cases, one has to subtract the value of 15% from the selling price.

Step-by-step explanation:
Answer:
x= -13
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 1 • 13 = 13
Step-2 : Find two factors of 13 whose sum equals the coefficient of the middle term, which is 14 .
-13 + -1 = -14
-1 + -13 = -14
1 + 13 = 14 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 1 and 13
x2 + 1x + 13x + 13
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x+1)
Add up the last 2 terms, pulling out common factors :
13 • (x+1)
Step-5 : Add up the four terms of step 4 :
(x+13) • (x+1)
Which is the desired factorization
-2x+3=5x-4
3+4=5x+2x
7=7x
x=1
y=5x-4=5*1-4=5-1=1
(1,1)
Answer:
Find the area of the square first
A = LW
= (149.5)(160)
= 23920 m^2
Find area of the triangle thing
A = BH / 2
= (268.5)(160)
= 42960 m^2
Add the two up to get the total area
23920 + 42960 = 66880 m^2
Hope this helps!
