Answer:
There's not enough information to answer the question.
Step-by-step explanation:
The question says that out of 84 kids, 3/7 bought their lunches. Then it asks how many of the 3/7 got pizza without providing a number of those who bought a different food. And so, there's not enough information to solve this question.
Answer:
36
Step-by-step explanation:
Answer: Both the equations when solved have different answers, the solutions for both the equation are given below. In the the first equation 4 (x-3)=16 , 4 is multiplied with both the terms in the bracket. Whereas, in the second equation 4x- 2 = 16 there is no variable to multiply with the LHS equation
Solution:
4 (x-3)=16
4x - 12 = 16
4x = 16 + 12
4x = 28
x = 7
4x - 3 = 16
4x = 16 + 3
4x = 19
x = 19/4
x = 4.75
Personally if I would of put it in a fraction it be 2/10
Between emma and dave, we have 7/10ths of the money
3x + 2x = 7/10
5x = 7/10
x=(7/10)/5
x= 14/100
Dave will get 28/100 or 7/25ths
Check : 30/100 Colin
42/100 Emma
+ 28/100 Dave
-----------
100/00
