£2200 is deposited in a bank paying 0.5% simple interest per annum. How much interest will have been paid after 18 years?

seraphim [82]

Answer:

The answer would be £198

principal (p) = 2200

Rate (R) = 0.5%

Time (T) = 18

Interest(I) = ?

Now,

or, Interest. = P×T×R/100

or, Interest = 2200×18×0.5/100

or, Interest = 19800/100

Hence, Interest = 198

22<br> Solve for x.<br> 3x - 5 = 10<br> x equals.....<br> help

kramer

Answer:

$x = 5$

Step-by-step explanation:

$3x - 5 = 10$

We want to isolate the x.

$3x - 5 = 10\\+5\;\;\;\;\;\;\;\;\; +5$

$3x = 15$

Now, we want the x not to have a coefficient. We want it just to be x =. We will do this via inverse operations. Since 3 x is 3 multiplied by x, we will divide each side by 3.

$\frac{3x}{3} \;=\;\frac{15}{3}$
