I'm not to sure about my work, since I got the wrong answer, then plugged in until they were equal. So, I'm not adding it so no one is confused by it. (because it isn't right)
y=3, x=4.
I think that it would be 25p multiplied by 1/2t
I am not for sure though
Answer:
31 scientific calculators
54 graphing calculators
Step-by-step explanation:
X = number of $15 calculators
Y = number of $67 calculators
X+Y = 85 then X = 85-Y
15X+67Y = 4083
substitute for X
15(85-Y)+67Y = 4083
1275 - 15Y + 67Y = 4083
reduce
52Y = 2808
Y = 54
X = 31
Answer:
5
Step-by-step explanation:
when the question asks for evaluate, always substitute the expression with the values given.
So, her x = -3 and y=4
So we find 1/2 of 2x - y
This is also half of -6-4 = -half of -10 = 5
Hope this helps,
Good Luck
