Answer:
19.59
Step-by-step explanation:
7.2+4.9 = 12.10+7.49 = 19.59
Both angles equal 117 so you put both angle equations together and set them equal to 117 then x= -2
Plug the -2 in for the x in both separate equations to get
M< XYW = 32°
M< WYZ = 85°
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
The circumference would be 6 inches because you do 3 times 2
Answer:
<h3>
EVEN</h3>
Step-by-step explanation:
the product of odd numbers is always odd
the product of even numbers is always even
the product of odd number and even one is always even
the <u>sum of two odd </u>numbers is always <u>even</u>
and the sum of two even numbers is always even
so if x is even number we have:
x²=x•x - even number
x⁴=x²•x² - even number
3x²=3•x² - even number
y = x⁴+3x² <u>- even number</u>
and if x is odd number we have:
x²=x•x - odd number
x⁴=x²•x² - odd number
3x²=3•x² - odd number
y = x⁴+3x² <u>- even number</u>
