Answer:
3x - y = 10
Step-by-step explanation:
y-5 = 3(x-5)
y - 5 = 3x-15
-3x+y= -10
3x - y = 10
Answer:
Step-by-step explanation:
Let yesterday's price be x
Discount percentage = 36%
Sale price = $ 560
(100-36)% of x = 560
64 % *x = 560
Yesterday's price = $ 875
A proportional relationship is also a direct variation.
The general equation of direct cvariation is
y = kx,
where k is a number.
In your case, if k = -1, then y = kx becomes y = (-1)x which is the same as
y = -x
Answer:
Step 4.
Step-by-step explanation:
To isolate the x variable, she subtracts 8 from both sides making it another subtraction property of equality justification.
See 5/6 is obviously more than 1/2 so 4/8 works
also 3/8 or 2/8 or 1/8
if you want all fractions then
5/6=x/8
times 24 both sides
20=3x
divide 3
6 and 2/3=x
basically x/8 such that x<6 and 2/3
examples
6/8
5/8
4/8
3/8
2/8
1/8
I would use the odd ones since the even ones simplify to non-eight denomenators
