Kesley is thinking of a number. She says that it’s the sum of a number and nine. Multiplied by 2/3, is equal to -18.
Aliun [14]

Answer:

Only the firsts and fourth choices (\frac{2}{3}(x+9)=-18 and \frac{2}{3}x+6=-18)

Step-by-step explanation:

Turn the equation into words:

"A number plus 9"

(x+9)

"Multiplied by \frac{2}{3}"

\frac{2}{3} (x+9)

"Is equals to -18"

\frac{2}{3}(x+9)=-18

Distribute to find the second equation:

\frac{2}{3}(x+9)=-18\\\frac{2}{3}x+6=-18

Ariana borrows $300 on a 6-year loan. she is charged 5% simple interest per year. How much interest is she charged for 6 years?
Aloiza [94]
So first we need to find how much is 5% of 300 , which we can discover by dividing 30p by 100 and multiplying by 5.
300÷100 ×5 = 15
So every year she pays $15 of interests
To find out how much she'll pay in 6 years pf interest , we just need to multiply 15 by 6
which is 90.
Then just add 90 to the original loan (300) to discover the total she will pay:

After 6 years, Ariane is charged $90 in interest. She pays a total amount of $390.
