Answer:

The solution of the given equations

x =4 , y = 1

Step-by-step explanation:

<u>Explanation</u>:-

<u>Step(l</u>):-

Given the system of equations -5x+13y = -7 ..(l)

                                                     5x+4y=24 ..(ll)

<u>Step(ll)</u>

Adding (l) and (ll) equations and cancelling '5x' terms we get

         13y+4y = -7 +24

               17y = 17

dividing '17' on both sides, we get

                y=1

<u>Step(lll):-</u>

Substitute y=1 in equation (l) , we get

-5x+13y = -7

-5x + 13(1) = -7

subtracting '13' on both sides, we get

-5x +13 -13= -7 -13

-5x = -20

Dividing '-5' on  both sides, we get

x = \frac{-20}{-5}

x = 4

<u>Conclusion</u>:-

The solution of the given equations

x =4 , y = 1

Dafna11 [192]

As given by the question

There are given that the profit of $16 milonin 2018 and $24 milion in 2019.

Now,

To find the profit,

\frac{24-16}{16}\times100

Then,

\begin{gathered} \frac{24-16}{16}\times100=\frac{8}{16}\times100 \\ =\frac{1}{2}\times100 \\ =0.5\times100 \\ =50\% \end{gathered}

Hence, the correct option is C.

What is the smallest multiple of 18 of the form 2A945B, where A and B are digits?
musickatia [10]

Answer:

219456

Step-by-step explanation:

It must end in 0,2,4,6,8 (divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).

The digit sum is 2+A+9+4+5+B=20+A+B.

We want to make A as low as possible because it's a higher digit than B.

If A is as low as possible, we have that the sum is 20+0+7=27. Uh-oh. B has to be even! So A=0 doesn't work.

If A=1, we have that the sum is 20+1+6=27. Yay!

So, the answer is \boxed{219456}
