Step-by-step explanation:
Answer:
x - 3y + z
Step-by-step explanation:
Terms are just names for objects inside the equation -- anything that isn't an operation. A coefficient the is the number a given term (variable) is being mulitpled by. In this case, -3 for y, and 1 for. x. We can deduce from this the start of the expression (x has no coeff. bc of multiplicative identity)
x - 3y
We know we are missing one term, and we also know that the third term cannot be constant, so it must be another variable. In this case I have chosen Z, in theory it shouldn't really matter but z is the best variable name in this case.
Answer:
Option 3. In step 3, she did not subtract one x from the left side
Step-by-step explanation:
we have the repeating decimal
0.272727...
Convert to fraction number
step 1
Let
x=0.272727...
step 2
Multiply by 100
100x=27.272727...
step 3
Subtract x from 100x
100x-x=27
99x=27
step 4
Find the value of x
x=27/99
therefore
Manda's work is not correct
In step 3, she did not subtract one x from the left side
