Determine if ( 5 2 , 7 2 ) and (-4,10) are solutions to the system of equations: x + y = -6 6x2 + 9y = 6

We don't know what ( 5 2 , 7 2 ) is supposed to represent, but it seems unlikely that the sum of those numbers is -6. Hence that is not a solution to the system.

The sum of -4 and 10 is +6, not -6, so that point is not a solution, either.

Neither offering is a solution to the equations.

The ratio of the sides of a triangle is 8:13:11. If the perimeter of a triangle is equal to 256, what is the length of the longe
s344n2d4d5 [400]
There asking what the numbers are by The ratios, what I did was did was multiply by 8 for each number 8•8=64 13•8=104 11•8=88 so now what you do is add up 64+104+88=256 those are your answers if you want to double check you will dived them by 8 so 64/8=8 104/8=13 88/8=11
Hope this helps :-)

-6Y-3=3-6Y what the answer
anyanavicka [17]

The answer is the number that 'Y' must be in order for
the equation to be true.
That number is called the 'solution' to the equation.
Here's one way to go about finding it:

You said that                      - 6y - 3  =  3 - 6y

Add  6y  to each side:                - 3 =  3

Let's stop right here.
Is there any value of 'Y' that can make  -3 = 3 ?
I don't think so.
Your equation has NO SOLUTION.

There is NO NUMBER that you can write in place of 'y'
in your equation
                           - 6y - 3  =  3 - 6y
                                                       and have it work out to be true. 

That's OK.  There are lots of equations that have no solution.

Likurg_2 [28]

Answer:

\$1.62

Step-by-step explanation:

Let

x-----> the cost of one pack of 6 cans of soup

step 1

Find the cost of 6 cans of soup

6(1.80)=\$10.8

step 2

Find the cost of one pack of 6 cans of soup

100\%-15\%=85\%=85/100=0.85

x=0.85(\$10.8)=\$9.18

step 3

Find the money saved

\$10.8-\$9.18=\$1.62
