Answer:
True
Step-by-step explanation:
Suppose a system contains a large number of variables than equations, then there is a need to make assumptions of some values for the extra variables in order to solve the system. So, the assigning of these values can be done in several ways. Thus, the system cannot contain a unique solution.
Also, for a system of the linear equation:
can have a unique solution if:
Augmented matrix(rank) = coefficient matrix(rank) = no. of variables.
Provided that there exist fewer equations and more variables,
Then;
coefficient matrix(rank) < no. of variables
Thus, the system cannot contain a unique solution.
Answer:
B
Step-by-step explanation:
If you look at the frequency, only 1/3 is odd. so I would pick 45. 100/3 is 33.3333, so yeah pretty close. The answer is B. Please mark brainliest if correct.
We can use a system of equations to solve this.
Notice that we are required to find 3 consecutive even integers.
This can be represented as x, y, and z, where x is the smallest integer, y is the next largest, and z is the largest of the three.
x = x
y = x + 2
z = y + 2
Take a moment to make sense of the above system of equations.
I can simplify the system a bit more by plugging in the second equation into the third one.
z = (x + 2) + 2
z = x + 4
Now the new system of equations is
x = x
y = x + 2
z = x + 2
Now for the second part of this problem. We are given this equation
2x + z = 268216
You may notice that we no longer need the second equation, y = x + 2. Also, the first equation is redundant, so we can ignore it.
That leaves us with this system:
z = x + 4
2x + z = 268216
What do you think we should do? We can plug in z to solve for x.
2x + (x + 4) = 268216
3x + 4 = 268216
3x = 268212
x = 89404
Now we know the first number in the sequence! Then we can find the other two numbers, because we know that the next numbers must be the next largest even numbers in sequence!
89404, 89406, and 89408 are your answers.
The number 1 is a the number 2 is b and the number 3 is a
40%=0.4
0.4+1=1.4
4.5(1.4)=6.3
The answer is $6.30
