So, we first add the 20 and 72 together and you will get 92.
What I like to do next is usually 92/100x8.5. The tax would be then 7.82
92 + 7.82 = 99.82 < 100
The answer is yes.
Answer:
60
Step-by-Step Explanation:
(200-125):125*100 =
(200:125-1)*100 =
160-100 = 60
Now we have: What is the percentage increase/decrease from 125 to 200 = 60
Answer: same.
Step-by-step explanation:
1) 13a=-5
Make a the subject of the formula by dividing both sides by 13(the coefficient of a)
13a/13=-5/13
Therefore a= -0.385
The second one). 12-b= 12.5
You take the 12 to the other side making b subject of the formula (-b in this case)
-b= 12.5-12
-b= 0.5
(You cannot leave b with a negative sign so you will divide both sides by -1 to cancel out the negative sign)
-b/-1= 0.5/-1
Therefore b=-0.5
The third one). -0.1= -10c
You will divide both sides by the coefficient of c(number next to c) which is -10
-0.1/-10= -10c/-10
Hence, c= 0.01
