Answer:
Yes
Step-by-step explanation:
Because
Step-by-step explanation:
subtract the whole equation by 85 on both sides to get v by itself on the left side
85-85-v=213-85
-v=128
Now we divide the whole equation by negative 1
-1v/-1=128/-1
v=-128
Hope that helps :)
Answer:
1). Rational
2). Irrational
3). Rational
4). Rational
5). Irrational
Step-by-step explanation:
To solve this question we should follow the rule,
"Addition of rational and an irrational number is an irrational number."
1). (rational number)
(negative rational number)
[rational number]
2). π → (Irrational number)
24 → (rational number)
π + 24 → (Irrational number)
Since addition of a rational and an irrational number is an irrational number.
3). = 2 (rational number)
5 (rational number)
2 + 5 = 7 (rational number)
4). (rational number)
(rational number)
(rational number)
5). (rational number)
→ (Irrational number)
→ (Irrational number)
In order to solve this question we first have to break down the terms.
Sum = Adding
Times = Multiplying.
The question states "3 times the sum of a number n and 12 is 45". In written form, it would be the following:
3(12+n) = 45
To solve this you first divide both sides by three and you'd be left with the following:
(12+n) = 15.
Then subtract 12 from both sides. Leaving you with:
n = 3
Answer:
A = 40/n
Therefore, she gave each friend 40/n ounces of jelly beans.
Step-by-step explanation:
Given;
Total amount of jelly beans To = 3 pounds = 3×16 ounces = 48 ounces
Total amount kept for family Ta = 8 ounces
Total amount given to friends = Ti
Number of friends = n
Amount given to each friend = A
Ti = To - Ta
A = Ti/n = (To-Ta)/n
A = (48 - 8)/n
A = 40/n
Therefore she gave each friend 40/n ounces of jelly beans.
