T = 1/5(x - y + z)
First, let's get rid of the 1/5. To do this, you can multiply both sides by the reciprocal, or 5/1.
(5/1)T=[(5/1)1/5](x-y+z)
5T = x - y + z
Now subtract x from both sides.
5T - x = -y + z
Add y to both sides.
5T - x + y = z
So the answer is:
z = 5T - x + y
Answer:
2x - 15
Step-by-step explanation:
None
Answer:
99
Step-by-step explanation:
x = 90 x 10/100 + 90
=> x = 900/100 + 90
=> x = 9 + 90
=> x = 99
Answer:
- A: 700
- B: he put the decimal point in the wrong place
Step-by-step explanation:
Part A: The problem 49/0.07 can be rewritten as 4900/7 by multiplying numerator and denominator by 100. Then it is more clear that the correct answer is (49/7)×100 = 700.
___
Part B: I've always had trouble reading Marco's mind, so I cannot tell you what mistake he made. I can tell you the decimal point in his result is in the wrong place.
