Answer:

<h2>X=-1 Y=0</h2>

Step-by-step explanation:

-10y+10y=0

Which leaves you with

9x = -9

and

5x = -5

Then you divide 9 off each side of 9x = -9 and 5x = -5

You will get

x = -1 for both

Then you might just try to find y but fail, thats because y is 0

A number is chosen at random from the integers 10 to 30 inclusive. Find the probability that the number is a multiple of 3.
kirill [66]

Answer:

For each part, find how many numbers have the stated characteristic, then divide by 21.

e.g. multiples of 5:

these would be 10, 15, 20, 25, and 30

so prob (a multiple of 5 ) = 5/21

Do the others the same way

Solve system of equation using elimination by addition.<br><br> Will give brainliest!!
DedPeter [7]

Answer:

x = 2, y = -3

Step-by-step explanation:

Add the 2 equations together, then solve for x.

(2x + 2y) + (3x - 2y) = (-2) + (12)\\ 2x + 3x + 2y - 2y = -2 + 12\\5x = 10\\x = 2

Now that we know the value of x, we can easily find y by substitution.

3x - 2y = 12\\3(2) - 2y = 12\\6 - 2y = 12\\-2y = 6\\y = -3

These are the answers

Mega Movies hosted a film premiere on Friday night. They charged $8 for adults and $5 for children. Ninety-two adults and childr
zmey [24]

Answer:

Step-by-step explanation:

a + c = 92.....c = 92 - a

8a + 5c = 688

8a + 5(92 - a) = 688

8a + 460 - 5a = 688

3a = 688 - 460

3a = 228

a= 228/3

a = 76 <==== adults

a + c = 92

76 + c = 92

c = 92 - 76

c = 16 <=== children

The difference of two numbers is 0.77. If the larger number is increased 5 times, then the difference becomes 77. Find the numbe
Lelu [443]

Let the two numbers are x and y

Let larger number = x

and smaller number = y

it means

x-y = 0.77

Now it says larger number is increased 5 times

So it now becomes 5x

So second equation becomes

5x -y =77

Now we have to solve these two equations

x-y = 0.77 and 5x-y = 77

multiply first equation by -1 and then add both equations

-x+y = -0.77

Now on adding we get

-x+5x +y -y = 77-0.77

4x = 76.23

Divide both sides by 4

x=19.0575

We get the larger number , now subtract 0.77 from this , we will get the smaller number

y=19.0575-0.77=18.2875

y=18.2875


Hence the larger number = 19.0575

Smaller number = 18.2875
