// Solve equation [1] for the variable x


[1] x = 2y - 1

// Plug this in for variable x in equation [2]

[2] 2•(2y-1) - 5y = -3
[2] - y = -1
// Solve equation [2] for the variable y


[2] y = 1
// By now we know this much :

x = 2y-1
y = 1
// Use the y value to solve for x

x = 2(1)-1 = 1

II 24x2 =52<br>in What base at the<br>number?​
amm1812

Answer: WE are multiplying in base 6

Step-by-step explanation:

24 x 2 = 52 can only be in base 6

because    2¹  4            2 x 4 = 8/6 = 1 rem 2.                        

             <u> x        2₆   </u>         2 x 2 + 1= 5

              <u> </u><u> 5      2          </u>

From the above , we can see theta 24 x 2 = 52 can only  be in base 6.

Because only 2 x 4 = 12 can be possible in base 6.

Counting in base 6  gives us that after 5, the next number is 10. Just like counting in the common base 10, which after 9 we get 1 0

in Base 10--- 1, 2,3, 4,5, 6,7,8,9,10

in Base 6---  1, 2, 3,4,5,10,11,12, 13,14  and so o

The graph shows the amount of money paid when purchasing bags of peanuts at the zoo:
Mumz [18]
The constant of proportionality would be "4"  ... proportional relationships are in the form of y = kx..  so in your ordered pairs, you can see that to get the 'y' coordinates you would have to multiply the 'x' coordinates by 4.
