Answer:
Given System of equation:
x-y =6 .....,[1]
2x-3z = 16 ......[2]
2y+z = 4 .......[3]
Rewrite the equation [1] as
y = x - 6 .......[4]
Substitute the value of [4] in [3], we get
Using distributive property on LHS ( i.e, )
then, we have
2x - 12 +z =4
Add 12 to both sides of an equation:
2x-12+z+12=4+12
Simplify:
2x +z = 16 .......[5]
On substituting equation [2] in [5] we get;
2x+z=2x -3z
or
z = -3z
Add 3z both sides of an equation:
z+3z = -3z+3z
4z = 0
Simplify:
z = 0
Substitute the value of z = 0 in [2] to solve for x;
or
2x = 16
Divide by 2 both sides of an equation:
Simplify:
x= 8
Substitute the value of x =8 in equation [4] to solve for y;
y = 8-6 = 2
or
y = 2
Therefore, the solution for the given system of equation is; x = 8 , y = 2 and z =0
Answer:
<h2>203.5 </h2>Solution,
Onions less than 60 grams = 2 --> Pickling
Onions greater than 120 grams = 5 + 3 = 8 --> Market
Onions between 60 and 120 = 13---> Processing
Total frequency = 2 + 8 + 13 = 23
Now,
Hope this helps ..
Good luck on your assignment...
Answer:
Step-by-step explanation:
First, deal with the product of the two powers of 2 inside the parentheses.
The two factors are powers of 2, so add the exponents.
You need a common denominator, 4, to add the fractions.
Now you have an exponent raised to an exponent. Multiply the exponents and reduce the fraction.
When a fraction is an exponent, the numerator is an exponent and the denominator is the index of the root. A denominator of 2 means a root index of 2 which means square root.
