Answer:
6
Step-by-step explanation:
If a number and a variable were together in a term, the number would the the coefficient. The coefficient would multiply the variable.
In '6x', the number '6' is the coefficient. '6' would be multiplying 'x'.
The correct answer should be 6.
The 2 is in the tenths place so it is two-tenths.
Two-tenths = 2/10= .2

Answer:
6.5 %
Step-by-step explanation:
The simple interest formula is
I = Prt
Data:
I = $1755
P = $3000
t = 9 yr
Calculation:
1755 = 3000 × r × 9
1755 = 27 000 r
Divide each side by 27 000
r = 1755/27 000 = 0.065 = 6.5 % APR
The annual percentage rate was 6.5 %.
X = the number
14 + 2x = 6x - 7
21 + 2x = 6x
21 = 4x
5.25 = x
The number is 5.25.
The answer is D. The temperature coefficient should be -1,5 as the temperature is dropping by the hour. Furthermore the starting temperature is 72 degrees so that should be added to the final answer. Therefore you get t = -1.5h + 72
