The division of whole numbers is commutative. true or false?

1 answer:

3 0

'Commutative' means you can work it in the other direction without changing it.
But 1/2 is not the same number as 2/1 . So I guess division is NOT commutative.

Please solve with working out simultaneous equations 3x+2y=12 2x+2y=10

Novay_Z [31]

Here, 3x + 2y = 12
2x + 2y = 10

Subtract 2nd from 1st equation,
x = 2

Now, substitute in 2nd,
2(2) + 2y = 10
2y = 10 - 4
y = 6/2
y = 3

In short, Your Answer would be: (2, 3)

Hope this helps!

Find the value of x and y Please help me. Thank you

Answer:

Step-by-step explanation:

let each angle=A

A+A+A=180

3A=180

A=180/3=60°

as the angles are equal so sides are equal.

16+y=46

y=46-16=30

applying sine formula

$\frac{30}{sin z} =\frac{46}{sin~80} \\sin~z=\frac{30}{46} \times ~sin~80=\frac{15}{23} \times sin ~80\\z=sin^{-1}( \frac{15}{23} \times sin ~80) \approx~39.96^\circ \approx40^\circ$

z+x=60

40+x=60

x=60-40=20°
