Your answer is probality B
Step-by-step explanation:
I LOOKED IT UP
S+m+l=28
4s+2m+l=58
6s+5m+4l=135
Eliminate the variable l from the first 2 equations
s+m+l=28
-4s-2m-l=-58
-3s-m=-30
Elminiate the variable l from the last 2 equations
6s+5m+4l=135
-16s-8m-4l=-232
-10s-3m=-97
Now solve for s and m using the 2 equations without l
-3s-m=-30
-10s-3m=-97
9s+3m=90
-10s-3m=-97
-s=-7
s=7
Then plug in s into one of the equations without l
-3(7)-m=-30
-21-m=-30
-m=-9
m=9
Now plus in s and m into one of the original 3 equations
(7)+(9)+l=28
16+l=28
l=12
Final answer:
Small=$7
Medium=$9
Large=$12
I know it only asks for large but I wanted to show you how to find them all for future reference. :)
Answer:
1500
Step-by-step explanation:
STEP 1 900 = 60% × Y
STEP 2 900 =
60
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 60 we will arrive at:
STEP 3 Y = 900 ×
100
60
STEP 4 Y = 900 × 100 ÷ 60
STEP 5 Y = 1500
Well, there are lots, but if you get rid of the parenthesis...
you would get 21c and that equals to 7(3c).
I believe the answer is positive rotation
