To solve this problem, we know that b = 1/2 and c = 1/4
The equation is 8(b/2) - (c + 4)
The problem is asking us to plug in 1/2 for b and 1/4 for c into the equation.
8(1/2/2) - (1/4 + 4) = 2 - 1/4 - 4 = -1/4 - 2 = - 9/4 (A)
You could do 21-5 and get the answer 16
A= 16+5 = 21
So therefor, he is 16 years old now.
solution:
3x-2y=1 , -9x-6y=-3.
solution system can be represent in (13,0) ( 1 3 , 0 ).
Answer:
4
Step-by-step explanation:
because The square root of 16 is 4, which is a rational number.
