Answer:
B. Start at -7 on the number line and move 11 to the right.
Step-by-step explanation:
<u>Given:</u>
We can add or remove only positive numbers on the number line to get it correct, so we need to open the parenthesis. When evaluated we get:
-7- (-11) = - 7 + 11 = 4
<u>Correct interpretation of of this expression is:</u>
- Start at -7 and add 11, thus move 11 points to the right, to get 4 as final point.
<u>Correct choice is:</u>
- B. Start at -7 on the number line and move 11 to the right.
It will take 19 years and 6 months for the account value to reach 2900 dollars
Step-by-step explanation:
Given
Principal amount = 1400 dollars
Rate = 5.5 %
Final value = A = 2900
We have to find t
So,
The formula for simple interest is:
![A = P(1+rt)](https://tex.z-dn.net/?f=A%20%3D%20P%281%2Brt%29)
Putting values
![2900 = 1400(1+0.055.t)\\\frac{2900}[1400} = 1+0.055t\\2.071 = 1+0.055t\\2.071-1=0.055t\\1.071 =0.055t](https://tex.z-dn.net/?f=2900%20%3D%201400%281%2B0.055.t%29%5C%5C%5Cfrac%7B2900%7D%5B1400%7D%20%3D%201%2B0.055t%5C%5C2.071%20%3D%201%2B0.055t%5C%5C2.071-1%3D0.055t%5C%5C1.071%20%3D0.055t)
Dividing both sides by 0.055
![\frac{0.055t}{0.055} = \frac{1.071}{0.055}\\t = 19.47\ years](https://tex.z-dn.net/?f=%5Cfrac%7B0.055t%7D%7B0.055%7D%20%3D%20%5Cfrac%7B1.071%7D%7B0.055%7D%5C%5Ct%20%3D%2019.47%5C%20years)
Rounding off to nearest tenth
19.5 years
Hence,
It will take 19 years and 6 months for the account value to reach 2900 dollars

You set 1/5 equal to x/200. Then you cross multiply the fractions to get 5x=200. You divide both terms by 5 to get x, which equals 40.
