Answer:
D.) 2/1
Step-by-step explanation:
QC is 8. BW is 4.
So the ratio of QC to BW is 8/4 which is equal to 2/1
Answer:
A3-a-c=b assuming you mean A=
Step-by-step explanation:
Basically, we'll be using properties of equalities to "balence out the equation" and shift all variables except for b to one side
1) Use multiplication prop. of equality
This property states that if we multiply one side we must multiply the other. We'll be doing this for the "3" portion.
3(A)=3((a+b+c)/3)
3A= a+b+c
2) Use subtraction prop of equality
This one states that if we subtract one side we must subtract the other. We will be doing this for the "a" and "c" portion
(3A)-a=(a+b+c)-a
3A-a=b+c
(3A-a)-c=(b+c)-c
3A-a-c=b
Hopefully that helps a bit T_T
As in step 2 the student added -2 only at one side of equation which is against the law of addition property of equality
so the correct option from above equation is
The student did not properly apply the addition property of equality to isolate x.
SO its B
hope it helps
