Answer:
x= -5/2
Step-by-step explanation:
4 - (2x+4)=5
4-2x-4=5
-2x=5
x=-5/2
It is systems of equations.
Let cups=c and l=liters
7c + 3l = 9.8
<span>5l - 9c = 6 </span>
<span>35c + 15l = 49 </span>
<span>15l - 27c = 18 </span>
<span>62c = 31 </span>
<span>c = 1/2 pint </span>
<span>l = 2.1 pint </span>
<span>1 cup = 1/2 pint 1 liter = 2.1 pints</span>
Marcus had 5 horses and Rachel had 5 times more. She had to divide them into 5 stalls. How many are in each stall?
Answer:
Option 3 is correct that is prime numbers.
Step-by-step explanation:
Even numbers are those which are divisible by 2
Prime numbers are the numbers which are divisible by 1 and the number itself
Since, we have to take only positive numbers
Carrie has taken out the set of even number within the set of prime number
So, 2 is the only number inside this eset because 2 is even as well as prime
Hence,universal set will be prime numbers
Therefore, Option 3 is correct that is prime numbers.
The answer is 3.14 m
The area (A) of the circle with radius r is: A = π · r²
The area of the quarter of the circle is: A1 = 1/4A = 1/4 · π · r²
We have:
A1 = ?
r = ?
π = 3.14
d = 4 m
A diameter d is the twice of the radius r: d = 2r.
Therefore, the radius is the half of the diameter: r = d/2
So, the area of the quarter circle would be:
A1 = 1/4 · π · r² = 1/4 · π · (d/2)² =1/4 · π · d²/2² = 1/4 · π · d²/4 = 1/16 · π · d²
A1 = 1/16 · π · d² = 1/16 · 3.14 · 4² = 1/16 · 3.14 · 16 = 3.14 m
