<u>Answer</u>:
40 cotton bags and 120 peanuts bags
Step-by-step explanation:
Let cotton candy bags be x and peanuts bag be y
x + y = 160 ........from Theory 1
4x + 2.5y = $460 ...............from Theory 2
<u>Making x the subject:</u>
x + y = 160
x = 160 - y ...........equation 1
4x + 2.5y = $460
4x = $460 - 2.5y
x = ($460 - 2.5y)/4 ..............equation 2
<u>Solving both equations simultaneously:</u>
160 - y = ($460 - 2.5y)/4
4(160 - y) = $460 - 2.5y
640 - 460 = - 2.5y + 4y
180 = 1.5y
y = 180/1.5
y = 120
<em>Therefore there are 120 peanuts bags</em>.
Then the number of cotton bags are: x + y = 160
: x + 120 = 160
: x = 40 cotton bags
Answer:
Set of milk, eggs, sugar and cornflour= 1250ml÷250ml= 5 sets
Number of eggs= 5 sets x 2 =10 eggs
250ml÷50ml=5
Amount of milk needed: 200ml÷5=40ml

Answer:
-5x²+26x-24
Step-by-step explanation:
(5x-6)(-x+4)
=5x(-x+4)-6(-x+4)
=-5x²+20x+6x-24
=-5x²+26x-24
Numerator = -3( - 8) = - 3 - 8 = -11
Denominator = 5 + 7 = 12
So the quotient = -11/12
Answer
- 11/12
