Step-by-step explanation:
its C. cause if f -g is equal to positive 4
X/2-15=-7
x-30=-14
x=-14+30
x=16
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
The answer is 18 cm because 2.4 cm is in 1 inch. you must multiply 7.5 by 2.4 and get 18
i think the best answer for this question is A)
