OPTION D = 2q is right answer
We can solve this system using elimination:
(x+y=24)3
3x+5y=100
3x+3y=72
-(3x+5y=100)
0x-2y=-28
y=14
We can then plug this back into one of the original equations:
x+14=24
x=10
We can check our answer by plugging this into both of the original equations:
10+14=24
24=24
3(10) + 5(14)=100
30+70=100
100=100
Therefore, there are 10 3-point questions and 14 5-point questions.
I'm not sure if this question was correctly transcribed but is it suppose to read find if x=15, find y = 6x+30 ?
If so then y = 120
The way it is written now, If x = 15 then 6x cannot equal 30 which is why I asked. Sorry if I'm not understanding the question.
Answer: Approximately 28
Step-by-step explanation: 55.25 + 250 = 305.25 next 305.25 ÷ 11 = 27.75 you can round to approximately 28
(Let me know if im wrong)
Answer: x=4
Step-by-step explanation: write down 11x-2+9x+1=19x+3, then combine the like terms... 20x-1=19x+3, then subtract 19x from both sides which will give you x-1=3, and 4-1=3 so x=4
