The "step 2" that Malik should take in order to solve the given system of equations is to add both equations.
Given to us
Step 1: Multiply the first equation with 3, while the second equation with 4,
6x + 12 y = 60
20x - 12 y = 44
Step 2: Add both the equations,
(6x + 12y) + (20x - 12y) = 60+44
Step 3: caluculate the value of x,
x = 4
Step 4: Substitute the value of x in equation 1,
2(4) + 4y = 20
8 + 4y = 20.
4y = 12
Y = 3
Step 5: The solution is (4, 3).
Hence, the "step 2" that Malik should take in order to solve the given system of equations is to add both equations.

Answer:
x = -5.33333333
Step-by-step explanation:
Using dist. prop
3x - 6 + 4x = 10x + 10
combine like terms
7x - 6 = 10x + 10
move the 6 over
7x = 10x + 16
move the 10x over
-3x = 16
divide by -3
x = -5.33333333
Answer:
Step-by-step explanation:
We have been given an equation . We are asked to find the solutions of our given equation.
We will use splitting the middle term method to solve quadratic equation.
We will split middle term of our given equation into parts such that whose product is and whose sum is 3.
We know that such two numbers are .
Using zero product property, we will get:
Therefore, the solutions for our given equation are .
Answer:
4.9 (rounded)
Step-by-step explanation:
Square root or 24 is 4.89, so it rounds to 4.9
Answer:
134 cubic centimeters
Step-by-step explanation:
The extended part is basically the volume of HALF A SPHERE.
First, the volume of full sphere is:
Hence, the half sphere volume would be:
We know the diameter is 8, radius is HALF OF THAT, so
Radius = 8/2 = 4
Substituting, we find (remembering to use 3.14 as pi):
To the nearest cubic centimeter, the answer is:
134 cubic centimeters
