Step-by-step explanation:
0.25 + 0.3 = 0.55
0.55 + 0.75 = 1.30
1.30 - 0.20 = 1.10
Answer:
<u>The original price of the coat was £ 275</u>
Step-by-step explanation:
1. Let's review all the information given for solving this question:
Sale price of the coat = £ 220
Discount from the original price = 20%
2. Let's find the original price of the coat
Original price of the coat = x
Sale price of the coat = £ 220
Sale price of the coat = x - 20%x
220 = x - 0.2x
220 = x - 2x/10 (0.2 = 2/10)
2,200 = 10x -2x (Multiplying by 10 at both sides)
2,200 = 8x
2.200/8 = 8x/8 (Dividing by 8 at both sides)
275 = x
<u>The original price of the coat was £ 275</u>
Answer:
121.5
Step-by-step explanation:
75% = 75/100
Step 2 - Mutiply percenatge fraction by the entire (100%) quantity
75/100× 162 = 121.5
Final result
75 percent of 162 is 121.5
5n + 7 = 7(n+1) - 2n
First distribute 7 to all terms inside the parenthesis
7(n) = 7n
7(1) = 7
5n + 7 = 7n - 2n + 7
Simplify. Combine like terms
5n + 7 = 5n + 7
True.
If you want to continue:
Isolate the n, move all variables to one side, and constants to the other
5n (-5n) + 7 (-7) = 5n (-5n) + 7 (-7)
0 = 0
True
hope this helps
