What is a reasonable estimate for the sum of 4 1/8+3 2/3+5 1/2
Bingel [31]
First, mentally add the whole numbers.
4+3+5=12
Now, look at the fractions. 1/8, 2/3, and 1/2.
2/3 is bigger than 1/2, so you can add in another whole number.
12+1=13
1/8 is tiny, and won't add a whole lot to the mix, so just leave that.
A reasonable estimate would be 13 1/8

What is the x-value in the solution to this system of linear equations?
ASHA 777 [7]

Answer:

  4

Step-by-step explanation:

The y-variable can be eliminated by adding 3 times the first equation to the second:

  3(2x -y) +(x +3y) = 3(11) +(-5)

  7x = 28 . . . .  simplify

  x = 4 . . . . . . . divide by 7

_____

Using Cramer's Rule, you can also find the x-value. The math is not so different.

  x = ((-1)(-5) -(3)(11))/(-1(1) -3(2)) = -28/-7 = 4

[5x+10y+15z=60<br> [2x+4y+6z=60<br> [x+2y+3z=60
Alla [95]

9514 1404 393

Answer:

  no solution

Step-by-step explanation:

The equations are inconsistent. The set of equations reduces to ...

  x + 2y + 3z = 12

  x + 2y + 3z = 30

  x + 2y + 3z = 60

No values of x, y, and z can satisfy all three equations. There is no solution.
