Step-by-step explanation:
The equation that Kaitlyn solved is as follows :
-5.4+x=12.2
The steps to solve it as follows :
Step 1. Add 5.4 to both sides,
-5.4+x+5.4=12.2+5.4
Step 2. 5.4 will cancel out as both have opposite signs
x=17.6
But Kaitlyn solved it as :
5.4.x=6.8
She has multiplied -5.4 and x which is wrong. The correct answer is 17.6.
Answer: 4.22
Step-by-step explanation:
Answer:Tn=29-2n
Step-by-step explanation:
Firstly u determine the differences between the terms and see if it's common. These case the common difference is -2 which means these is a linear pattern.
Now Tn=a+(n-1)d
Tn=27+(n-1)(-2)
Tn=27-2n+2
Tn=29-2n
Answer:
0.05
Step-by-step explanation:
When you subtract 1 3/4 by 0.25, as a decimal is 1.5 and when you divide 1.5 by 30, you'll get 0.05.
Tell me if I'm wrong or not.
