Answer:
the answer would be 105!!
Step-by-step explanation:
5×3=15
15×7=105 aka our answer
15x15= 225
15x + 105= 225
15x= 225-105
15x= 120
X=8
X+ (x+1) + (x+2) + (x+3)…etc all the way up too +(x+14)=225
The first five numbers of the set: 8, 9, 10, 11, 12
200,000 is 20% of 1,000,000
There is no solution. Here is the explanation with both of the methods :)
