0.27 divided by 0.03 = 9


think of it this way it's like doing it 27 divided by 3 which is = 9


but then u see
9x3=27
9x0.3=2.7

so that must mean
9x0.03=0.27
u basically move the decimal point, in this problem its moved 2 or 3 times.

Help please math ..??
astraxan [27]

Answer:

(3, - 1)

Step-by-step explanation:

5x - 4y = -11

2x + 3y = -9

Multiply the top equation by 2 and the bottom equation by - 5 to cancel out the x's.

10x - 8y = - 22

- 10x - 15y = 45

Cancel out x's.

-8y = - 22

- 15y = 45

Add like terms.

- 23y = 23

Can't have a negative variable to flip them.

-23 = 23y

Divide.

y = - 1

Input y into one of the equations and solve for x.

2x + 3(-1) = -9

Simplify.

2x -3 = -9

Cancel out -3 by adding 3.

2x = -6

Divide.

x - -3

Which of the following points are on the line given by the equation y equals 2x?
Rina8888 [55]

Answer:

(5,10)

(3,6)

Step-by-step explanation:

The equation y=2x means that 2 multiplied by the first value would equal the second value, so this means that the second value is twice as much as the first value.  This is not true for the first option because 8 is not twice of 16, and this is the same for (4,6), (4,2), and (1,3).  Therefore (5,10) and (3,6) work.

22.11 divided by 11?
Dimas [21]

Answer: 2.01

Explanation: I rounded 22.11 two 22. So when you divide it by eleven is 2. Then you divide 11 by 11. Which is one, and it seems it was in the hundreths place so you add a cero before the one.

10 POINTS! PLEASE HELP!! The illustration shows a compact disc tray that holds five CDs. The radius of each compact disc is 9 cm
MariettaO [177]

We can see that there are 5 CDs, each of radius 9 cm

<u>Area occupied by 1 disc:</u>

Area of a circle = πr²

Area of disc = π(9)²

Area of disc = 3.14 * 81 = 254 cm²

<u>Area occupied by 5 discs:</u>

Area occupied by 5 discs = Area occupied by 1 disc * 5

Area occupied by 5 discs = 254 * 5

Area occupied by 5 discs = 1270 cm²
