3(-3)-4=9-4=13

3(3)-4=9-4=5

$${\frac{{\mathtt{8}}}{{\mathtt{14}}}} = {\frac{{\mathtt{4}}}{{\mathtt{7}}}} = {\mathtt{0.571\: \!428\: \!571\: \!428\: \!571\: \!4}}$$

Interest compounded annually is modeled by the exponential function, A=A0(1+r)t where r is the growth rate, A0 is the initial amount invested, A is the final amount and t is the number of years.

In this problem:

A0=1000t=18A=1800

The equation that models the bank account is:

1800=1000(1+r)18

To solve for r, first divide both sides by 10000.

18001000=(1000(1+r)18)1000

1.8=(1+r)18

You must now take the 18^th root of each side.

1.03319=1+r

0.03319=r

After converting the decimal to a percent,the rate is approximately 3.32%.

$${\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{10}} = {\mathtt{19}}$$  

$${\mathtt{23}}{\mathtt{\,\times\,}}{\mathtt{23}} = {\mathtt{529}}$$ 23 squared is 529

hahha oh mine bad did not read it right hahah lol

Thw squared root 23 is 4.79 which i about five 

28%of $6000 equal to 1680 i think because you put the percent into decailmal which is 0.28 now time it by 6000 which u get 1680 not sure if i am right

9/4 x 1 1/6 = 2 15/24 reduces that number
