Number of weeks in a year divided by 6, then multiply that answer by $108
Answer:
x = 0
y = 2
Step-by-step explanation:
3x + 9y = 18 ---------eqn 1
y = x + 2---------eqn 2
Substitute eqn 2 into eqn 1, for the value of y
3x + 9( x + 2) = 18
3x + 9x + 18 = 18
12x + 18 = 18
12x = 18 -18
12x = 0
Divide both sides by 12 , to get the value of x.
12x/ 12 = 0/12
x = 0
Substitute x = 0 into eqn 2
y = x + 2
y = 0 +2
y = 2
Hint: to confirm the values
x = 0
y = 2
Let's take eqn 1 ,
3x + 9y = 18
3(0) + 9(2)
= 0 + 18
= 18
Correct
Let's take eqn 2
y = x + 2
Let's find y
y = 0 + 2
y = 2
Correct too
Answer:
2 2/5
Step-by-step explanation:
It is because the 2 wholes and 2/5
C, because 12 squared plus 16 squared equals 544, then you take the square root of
Add up the numbers and if the sum is divisible by 3 the original number is also divisible by 3.
ex: 357÷3
3+5+7=15
15÷3=5
so 357 is divisible by 3.
