Its a simultaneous equation:
lets make "x" the used games and "y" the new ones

4x + 2y = 84
6x + y = 78. (multiply this by 2 to cancel out y)
12x + 2y = 156

so now we subtract them:
12x - 4x = 156 - 84
x = 9
used games cost $9
new games cost 78 - 6(9) = $24

Janet has $120 but she already bought 3 NEW games so:
120 - 3(24) = $48 left

48/9 = how many used ones she can buy = 5. something

she can buy 5 used

If a to the power x by y is equal to 1 then the value of x is​
Mazyrski [523]

Answer:

a^x/y=1              x: 0

Step-by-step explanation: w.k.t,        a^0=1( any variable raised to 0 is 1)

                                    so, here the exponent is x/y which should have been 0 so that answer was 1.

What is the value for y?<br><br><br><br> Enter your answer in the box.
Anna007 [38]

Answer:

y = 28

Step-by-step explanation:

since this is an Isosceles triangle (x - 5)° must be equal to 34°

x - 5 = 34

x = 39

the sum of interior angles in a triangle is equal to 180°

if the two angles 34 + 34 = 68

Then the third angle is 180 - 68 = 112°

4y = 112

y = 28
