On your calculator your write 8 on the y axis and 4 on the x axis
$304 is the answer because 456/3 and then multiply by 2
you can't factorize it in rational numbers
Amount of money collected in the 2-day fundraiser is represented by the following equations:
- 12x + 4y = 152 .................. (i)
- 32x + 12y = 420 .................. (ii)
where x is the cost of a chicken lunch and y is the cost of a vegetarian lunch
Multiplying (i) with 3 and subtracting it from (ii)
36x + 12y - (32x + 12y) = 456 - 420
⇒ 4x = 36
⇒ x = 9
Put value of x in (i)
⇒ 12 × 9 + 4y = 152
⇒ 108 + 4y = 152
⇒ 4y = 44
⇒ y = 11
Hence, cost of the vegetarian meal is 11.
Answer:
w=4
Step-by-step explanation:
7-16=-9
39-x=-9
39+9=48
39-48=-9
x=48
48/12=4
w=4
