Answer:
Shane started the problem correctly
Step-by-step explanation:
We are given problem (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
We need to find who started the problem correctly.
The problem should be started by converting the mixed fraction into improper fraction i,e
Now we will solve bracket by multiplying -1 with term inside the bracket i.e
Let's compare both the procedures now:
Mariah:
Therefore, Mariah did not start the problem correctly.
Shane:
Therefore, Shane started the problem correctly.
Answer:
In B) y = x/7 , the constant of proportionality is 7.
Step-by-step explanation:
Two quantities X and Y are said to be in proportion if and only if
X = kY or, ,
where k = Proportionality Constant.
Here, 7 is the constant of proportionality. Then,
A . y = 14x
here, ≠ 7
B . y = x/7
here, = constant of proportionality .
C. y = x
here, ≠ 7
