Answer:
x = 5
Step-by-step explanation:
Step 1: Write equation
3x - 4 = 2x + 1
Step 2: Solve for <em>x</em>
<u>Subtract 2x on both sides:</u> x - 4 = 1
<u>Add 4 on both sides:</u> x = 5
Tenths means 1/10
hunderths means 1/100
how many 1/100 makes 4/10?
1/100 times what=4/10
multiply both sides by 100/1
what=400/10=40
answer is 40 hunderths=4 tenths
Answer:
c² √a²+b²
Step-by-step explanation:
use that formula
Given parameters:
Cost price of the article = Nu.28.30
Selling price of the article = Nu.29.30
Unknown:
Gain percentage = ?
The gain percentage is the same as the percentage profit on a trade.
The formula is given as:
Gain percentage =
Profit = Selling price - Cost price
= Nu.29.30 - Nu.28.30
= Nu. 1
Now input the parameters and solve;
Gain percentage =
= 3.5%
The gain percent is 3.5%
