x = -2
y = 3
z = - 2
Expression2x - 3y - z
Substitute and solve
2(-2) - 3(3) - (-2) Notice that the 3 has 1 minus and the 2 has 2 minus signs. That means the the -3*3 = - 9 and - -2 = 2
-4 - 9 + 2
- 13 + 2
-11

Answer:Se dice que cualquier número que no se pueda expresar como una razón de dos enteros es irracional. Su representación decimal no termina ni se repite infinitamente, sino que se extiende para siempre sin repetición regular. Ejemplos de números tan irracionales son la raíz cuadrada de 2 y π.
Step-by-step explanation:
Using proportions, it is found that the farmer has planted 258 acres.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
He plants 413 acres during the entire year, hence, considering he plants an equal amount daily, and the year is 5/8 over, the amount he has planted is:
A = (5/8) x 413 = 258 acres.

Answer:
(8,21)
Step-by-step explanation:
Since both equations equal y, set both equaitions equal to each other
and solve for x
4x-11=x+13 , subtract x from both sides
3x-11=13, add eleven to both sides
3x=24, divide both sides by 3 to get x alone
x=8
Substitute x=8 into either equation to solve for y
y=4(8)-11
y=32-11
y=21
