Answer:

It's being divided by 5.

Step-by-step explanation:

In this question, the variable being used in the equation is being divided by 5. This is represented by the / symbol in the equation which is the symbol for division. If we multiply both sides by 5 we can isolate the variable M and get its value like so...

M/5 = -40 ... multiply both sides by 5

M = -200

Therefore in this scenario, the value of M would be -200

madreJ [45]

Answer:

$(x, y) = \left(\frac{3}{2}, \frac{\sqrt{3}}{2}\right)$

Step-by-step explanation:

The rectangular coordinates of the point are:

$(x,y) = \left(\sqrt{3}\cdot \cos\frac{\pi}{6}, \sqrt{3}\cdot \sin\frac{\pi}{6}\right)$

$(x, y) = \left(\frac{3}{2}, \frac{\sqrt{3}}{2}\right)$

What is the perimeter

Slav-nsk [51]

Solution:

Perimeter is the sum of the figure's sides.

10 + 10 + 4 + 10 + 4 + 10 + 10 + 30 = Perimeter of figure

<u>Simplify the expression:</u>

5(10) + 2(4) + 30 = Perimeter of figure
=> 50 + 8 + 30 = Perimeter of figure
=> 88 cm = Perimeter of figure

Arrange the steps to solve this system of linear equations in the correct sequence.

Gwar [14]

Answer:

x=-3

y=1

Step-by-step explanation:

x+y=-2...(1)

2x-3y=-9...(2)

In equation (1) make x the subject of formula by subtracting y from both sides

x=-2-y...(3)

Substitute (3) into (2)

2(-2-y)-3y=-9

Open the bracket

-4-2y-3y=-9

Collect like terms

-2y-3y=-9+4

-5y=-5

Divide both sides by-5

y=1

Substitute y=1 into(3)

x=-2-1

x=-3

Therefore,x=-3,y=1

How much should you invest at 5% simple interest in order to have a balance of 1,200 in two and a half years

BARSIC [14]

Answer:

We should invest 9600 .

Step-by-step explanation:

Interest received in Two and a half year = 1,200

So, Interest that should be received in a year = 1200× $\frac{2}{5}$

= 480

Interest rate = 5%.

Let we had invested amount X.

Thus 5 % of X we will get in a year as interest

Which is $\frac{5}{100}$ ×X = $\frac{X}{20}$ .

It is also equal to 480 as calculated above,

So. X = 480×20 = 9600.

Thus,

We should invest 9600 .
