For this, you have to calculate Unit rates of all of them.
Unit rate of sample 1, = 10/25 = $0.4
U.R. of sample 2, = 18.50/50 = $0.37
U.R. of sample 3, 27.20/80 = $0.34
So, first one is costlier!!!
Answer:
A. (3, 10)
Step-by-step explanation:
You are told that ...
(x, y) = (number of accessories, dollars)
and you are told that ...
number of accessories = 3
dollars = 10
so the ordered pair is ...
(x, y) = (3, 10) . . . . Point A
Step-by-step explanation:
A - 3×3×-3×-3×-3 = 243
B - 3×-3×3 = 27
C - 3×3×-3×-3 = -81
D - 3×-3 = 9
The correct option is C
Answer:
X=6
Step-by-step explanation:
5(x+2)=6x+3x−1
<u><em>Step 1: Simplify both sides of the equation.</em></u>
5(x+2)=6x+3x−14
(5)(x)+(5)(2)=6x+3x+−14(Distribute)
5x+10=6x+3x+−14
5x+10=(6x+3x)+(−14)(Combine Like Terms)
5x+10=9x+−14
5x+10=9x−14
<u><em>Step 2: Subtract 9x from both sides.</em></u>
5x+10−9x=9x−14−9x
−4x+10=−14
<u><em>Step 3: Subtract 10 from both sides.</em></u>
−4x+10−10=−14−10
−4x=−24
<u><em>Step 4: Divide both sides by -4.</em></u>
−4x / -4= −24 / −4
x=6
