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:
option B)
Step-by-step explanation:
According to the given conditions, the total number of outcomes are 24.
The probability that of drawing hearts card is
P=
total number of hearts cases= 6
thus P= 
now the probability of 4 or 6 is,
P=
thus P= 
thus, by multiplication law,
final probality is P= 
P=
First we need to find the volume of water that can be filled in water
Then we will use the equation that
1 gallon = 3.8 lires
Then by using this we will calculate the amount of cup used by equalizing with litres and then by gallons and then calculate number of cups in gallons
Answer:
Yes, these create an isosceles triangle, where two sides are equivalent
Step-by-step explanation:
4x - 12 < 16 + 8x
Bringing like terms on one side
-12 - 16 < 8x - 4x
-28 < 4x
-28/4 < x
-7 < x
