Answer:
7x-5 = 9
x = 2
Step-by-step explanation:
Let x be the number
7x-5 = 9
Add 5 to each side
7x-5+5 = 9+5
Divide each side by 7
7x = 14
7x/7 = 14/7
x=2
A is 30% more than B. So, A = B + 30% of B = B + 30/100 *B = B + 3/10 *B = 13/10 *B. B is 60% less than C. So, B = C - 60% of C = C - 60/100 *C = C - 3/5 *C = 2/5 *C.
X= -4; f(x)= -15
X= 2; f(x)= 3
X=5; f(x)= 12
Okay to start off the problem you make a fraction of 360/3. you then divide 360 by 3. 360÷3=120. so the rate and unit rate is 120 customers
