we can determine the value of this number by setting an equation
the sum of the number and 7, multiplied by 3, is equal to 8 plus the number.
making x= the unknown number, we can say:
3(x+7) = 8 + x
now we can distribute the 3 and solve for x
3x+21 = 8+x
2x+21=8
2x= -13
x = -6.5

Answer:
B) 5
Step-by-step explanation:
$6000 × 0.03 = $180 - this means that every year, $180 is added to the invested amount.
We can now do $900 ÷ $180 to find out the number of years the money was invested for: $900 ÷ $180 = 5
The money was invested for 5 years
Hope this helps!

Answer:
![10\frac{2}{15}](https://tex.z-dn.net/?f=10%5Cfrac%7B2%7D%7B15%7D)
Step-by-step explanation:
We want to write
in simplest form
We convert the mixed numbers to improper fraction.
![\frac{16}{5}*\frac{19}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B5%7D%2A%5Cfrac%7B19%7D%7B6%7D)
We look for common factors to cancel out
![\frac{8*2}{5}*\frac{19}{2*3}](https://tex.z-dn.net/?f=%5Cfrac%7B8%2A2%7D%7B5%7D%2A%5Cfrac%7B19%7D%7B2%2A3%7D)
![\frac{8}{5}*\frac{19}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B5%7D%2A%5Cfrac%7B19%7D%7B3%7D)
We multiple the numerators and the denominators to get:
![\frac{8*19}{5*3}](https://tex.z-dn.net/?f=%5Cfrac%7B8%2A19%7D%7B5%2A3%7D)
This simplifies to:
![\frac{152}{15}=10\frac{2}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B152%7D%7B15%7D%3D10%5Cfrac%7B2%7D%7B15%7D)
