X+y=31.5
x-y=5.25
add 2 equations
x+y+x-y=31.5+5.25
2x=36.75
x=18.375
y=31.5-18.375=13.125
check : 18.375+13.125=31.5, 18.375-13.125=5.25
so
Answer:
18.375 and 13.125

You have to divide the numbers that do not have the variable y in it.
Answer C
When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy. Water has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius
Answer:
Step-by-step explanation:
-4y = -5x + 16
4y = 5x - 16
y = 5/4x - 4
perp. -4/5
y + 8 = -4/5(x - 5)
y + 8 = -4/5x + 5
y = -4/5x - 3
