Answer:
0.75x = 23.97
Step-by-step explanation:
The total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75.
275.5 would be the answer. Round it up to 276 though and that's the answer.
Answer:
-5
Step-by-step explanation:
To find the common difference, take the second term and subtract the first term
-2 - 3 = -5
Check with the third term and the second term
-7 - (-2) = -7 +2 = -5
The common difference is -5
The expressions for the ages of Jhonny, Freddy, Estefania and the total sum written in terms of a are :
- Jhonny = a
- Freddy = 3 + 2a
- Estefania = 2 + 3a
- Total ages = 6a + 5
Johnny's age = a
Freddy's age is 3 years more than 2 times Johnny's age ; hence, Freddy's age = 3 + 2a
Estefania's age is 2 years more than 3 times Johnny's age ;
Hence, Estefania's age = 2 + 3a
The ages of Jhonny, Freddy and Estefania's ages can be written using the addition operator thus :
a + (3 + 2a) + (2 + 3a)
a + 3 + 2a + 2 + 3a
a + 2a + 3a + 3 + 2
6a + 5
Therefore, the ages of Jhonny, Freddy, Estefania and the total sum of their ages are a, 3+2a, 2+3a, 6a+5 respectively.
