3? i don’t know or maybe 10
Odd integers are 2 apart
the 3 consecutive odd numbers are x,x+2, x+4
sum is x+x+2+x+4 or 3x+6
the sum is 15 more than 2 times middle one
3x+6=15+2(x+2)
3x+6=15+2x+4
3x+6=19+2x
minus 2x both side
x+6=19
minus 6 both sides
x=13
x+2=15
x+4=17
they are 13,15,17
Week 7 And the amount is 230$
You can check it by getting a Graphing Calculator and Inserting the Equations into y= And Go down the list where x=7 and the two variables are the same Number
-7 = x/2 + 1
Subtract one from both sides
-8 = x/2
Multiply two on both sides
-16 = x
Answer, x = -16
Checking,
-7 = (-16/2) + 1
-7 = -8 + 1
-7 = -7
