<u>Answer:</u>

The solution of −3/8÷−6/7 is \frac{7}{16}

<u>Solution:</u>

The given equation is -\frac{3}{8} \div-\frac{6}{7}

In the above equation we can see that more than one mathematical operator has been used.

To figure out which one to solve first we need to follow the BODMAS rule.

BODMAS mean brackets, of, division, multiplication, addition and subtraction.

To make the calculation simply we will invert one of the fractions. This will make the division operator into a multiplication one.

-\frac{3}{8} \times-\frac{7}{6}

This equation can be simplified as 6 is divisible by 3. Also the negative signs cancel out each other.

\frac{1}{8} \times \frac{7}{2}

On multiplying the remaining terms we get;

\frac{7}{16}

Hence the solution of −3/8÷−6/7 is \frac{7}{16}

the length of a rectangle is equal to triple the width . if the perimeter is 8 centimeters .what is the length and the width of
madam [21]

Answer:

Length = 3 cm

Width = 1 cm

Step-by-step explanation:

Let the length of rectangle be l and width of rectangle be w.

According to problem,

l = 3w  {Length of rectangle is equal to triple the width}

And Perimeter,P = 8 cm

Since, P = 2 ( l + w )

or 8 = 2( l + w)

Plug l =3w in the above perimeter equation.

We get:

8 = 2( 3w + w)

8 = 2(4w)

8 = 8w

or    w = 1 cm

Then length ,l = 3w =3 * 1 = 3 cm

Hence length of rectangle is 3cm and width of rectangle is 1cm.

dangina [55]

Answer: $107,836.69 or about $107,837 (to the nearest dollar)

Step-by-step explanation:

Formula to the  accumulated amount received after investing principal amount (P) at rate of interest (r) compounded monthly for t months :

A=P(1+\dfrac{r}{12})^{t}

As per given , A = $130,000

r= 7.5% = 0.075

t= 30 months

Now,

130000=P(1+\dfrac{0.075}{12})^{30}\\\\\Rightarrow 130000=P(1+0.00625)^{30}\\\\\Rightarrow 130000=P(1.00625)^{30}\\\\\Rightarrow 130000=P \times1.20552661036\\\\\Rightarrow\   P=\dfrac{130000}{1.2055266}=107,836.69

Hence he need to invest $107,836.69 .

add 1x to each side
should be left with 3x=6
divide both sides by 3 to get x alone
your answer then is x=2
