Answer:
200
Step-by-step explanation:
If the second digit of 167 is 5 or above it will be rounded to 200.
(-2+3)/(6+4)= 1/10
y+3=1/10(x + 4)
y + 3 = (1/10)x + 4/10
y + 30/10 = ( 1/10)x + 4/10
y = (1/10)x + 4/10 - 30/10
y = (1/10)x - 26/10
y = (1/10)x - 13/5
10(y = (1/10)x - 13/5)
10y = x - 26
-x + 10y = -26
20 because if you think about it 2/3 is equal to 20/30.
Answer: 2.5%
3967.50 - 3450 = 517. 50
i = prt/100
i = 517.50, p = 3450, t = 6
517.50 = 3450 x r x 6/ 100
517.50 = 20700r/100
517.50 = 20700r
517.50/20700 = r
r = 0.025 = 2.5%
