Make them all fractions over 4, so 3 would be 12/4, and 1 1/4 would be 5/4 so add them together
12/4+5/4= 17/4 then divide by 4 to reduce it, to get 4 1/4
64=2^6, 72=2^3*3^2
gcd (64,72)=8
Therefore 64/8 =8
72/8=9
gcd (8,9) =1
8,9 are relatively prime.
Thus, 64/72=8/9
Step-by-step explanation:
-3x+3x-(b÷2)=-3
0-(b÷2)=-3
-(b÷2)=-3
b=-2×-3=+6
=> b=6
Answer:
C
Step-by-step explanation:
most of the dots are along the line C
X=0.5
y=1
(4x0.5) + (7x1) = 9
2 + 7 = 9
