Simplify (3(3n-10) - 2n + 5). The solution for (n) is: a) 2n - 25 b) 5n - 35 c) 7n - 25 d) 7n - 25
Answers
Answer:
7n - 25
Step-by-step explanation:
given
3(3n - 10) - 2n + 5 ← distribute the parenthesis by 3
= 9n - 30 - 2n + 5 ← collect like terms
= (9n - 2n) + (- 30 + 5)
= 7n + (- 25)
= 7n - 25

Answer:
The cost of the fencing is $1425 .
Option (A) is correct .
Step-by-step explanation:
As the sides given in the figure are
I.e
Thus
Perimeter of the fencing = 39.3 + 75.5 + 50.2 + 120
= 285 foot
As the fencing costs $ 5.00 per foot .
Cost of the fencing = 285 × 5
=$1425
Therefore the cost of the fencing is $1425 .
Option (A) is correct .
39+75+120+50 =284
What you have left: 1/2, 1/3, 1/6
Make the 1/3 to 1/6:
1 (•1)/3 (•2) = 1/6
1 (•2)/6 (•1) = 2/6
1/6 + 2/6 = 3/6 = 1/2
1/2 + 1/2 = 1
284+1
285 feet • $5 = $1425

Answer:
5F = -15C ( 1F=-17.2222222)
Final answer:
The highest temperature on a winter day of 5°F is equivalent to -15°C. This is derived by using the formula to convert Fahrenheit to Celsius: C = (5/9)*(F - 32). Therefore, the temperature in Celsius is -15°C.
Explanation:
The problem is asking for the conversion of temperature from Fahrenheit to Celsius. The formula to convert Fahrenheit to Celsius is C = (5/9)*(F - 32). Let's use it to solve the question.
Given that the Fahrenheit (F) temperature is 5°F, the Celsius (C) temperature would be calculated as: C = (5/9)*(5 - 32), resulting in a Celsius temperature of about -15°C. This means that 5°F is equivalent to -15°C.

5:7
Step-by-step explanation:
To simplify the ratio 25:35, you can divide both numbers by their greatest common divisor (GCD). In this case, the GCD of 25 and 35 is 5. So, dividing both numbers by 5 gives us the simplified ratio: 5:7.
Answer:
25:35 or 25/35 = 5/7 or 5:7
Step-by-step explanation:
1. Start with the ratio 25:35.
2. Find the HCF of 25 and 35. The HCFof 25 and 35 is 5.
3. Divide both numbers in the ratio by the HCF.
25 ÷ 5 = 5
35 ÷ 5 = 7
4. The simplified ratio is 5:7.
Therefore, the simplified form of the ratio 25:35 is 5:7.
