Answer:

Step-by-step explanation:

We have that:

x=10.8

x +29.2=40

because

10.8+29.2=40

Another possible expression is

50.8 - x =40

This is so, because:

50.8 -10.8 =40

Another one is:

2x+18.4=40

This is so because:

2*10.8+18.4=40

So, all you need to do is to substitute 10.8 for x in the given expression,

If the solution equates to 40, then that's your answer

Answer:36

Step-by-step explanation:

$\frac{4}{7} =\frac{48\\}{84}$

7*12=84

<h3>What is compound interest?</h3>

Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-

$A=P[1+\dfrac{r}{n}]^{nt}$

a) The amount in the bank after 6 years if interest is compounded annually.

$A=P[1+\dfrac{r}{1}]^{t}\\\\\\A=6000[1+\dfrac{0.01}{1}]^{ 6}$

A= $6369

b) The amount in the bank after 6 years if interest is compounded quarterly.

$A=P[1+\dfrac{r}{4}]^{4t}\\\\\\A=6000[1+\dfrac{0.01}{4}]^{4\times 6}$

A= $6090

c ) The amount in the bank after 6 years if interest is compounded monthly.

$A=P[1+\dfrac{r}{12}]^{4t}\\\\\\A=6000[1+\dfrac{0.01}{12}]^{12\times 6}$

A=$6030

Hence the amount for the investment of $6000 will be a.$6369 b. $6090 and c.$6030.
