uhhhhhhhhh
Step-by-step explanation:that will bee
20x+30y= c(total cost of money)
Part B: 20(10)+5(30)
200+150=$350
Let x = original price in dollars
x is the original price
9% of this original price is equal to 0.09x
subtract: x - 0.09x = 0.91x
The discount price is equal to 0.91x and it's equal to 90 dollars, so they must be the same value. Ie.
0.91x = 90
0.91x/0.91 = 90/0.91
x = 98.9010989
x = 98.90
So the original price is $<span>98.90</span>
The values of <span> f(-2), f(-0.5), and f(3) can be solved by substituting the values inside the parentheses to the function to the variable x. We do as follows:
</span><span>1. f(x)=-x+4
</span>f(-2) =-x+4 = 2+4 = 6
f(-0.5) =-x+4 = 0.5 + 4 = 4.5
f(3) =-x+4 = -3+4 = 1<span>
2. f(x)= 3/8x-3
</span>f(-2)= 3/8x-3 = -15/4<span>
f(-0.5) </span>= 3/8x-3 = -51/16<span>
f(3) </span>= 3/8x-3 = -15/8
Hope these answers the question.
Answer:
159.69*0.75 = 119.76
Step-by-step explanation:
Cause we have a 25% discount, that means that the skatebord costs 75% of its original price.
The 75% of the original price is the 75/100 part (0.75)
