So, first off it would help if you could define the terms irrational number and integer. Well, an irrational number is basically any real number that can't be expressed as a ratio of integers. They also cannot be represented by terminating or continuing decimals. And an integer is pretty much any number that cannot be written as a fraction or decimal, such as -2, 13, 257. It is not 2 and 1/2, or 4.75. Those would not be integers. Do you think you can figure out the difference?
Answer:
(2, 3).
Step-by-step explanation:
3x+2y=12
6x+3y=21 Multiply the first equation by 3 and the second by 2:
9x + 6y = 36
12x + 6y = 42 Subtract:
-3x = -6
x = -6/-3 = 2.
Plug x = 2 into the first equation:
3(2) + 2y = 12
2y = 12 - 3(2)
2y = 6
y = 3.
Answer:
3
Step-by-step explanation:
Given
- 1 - (- 6 + 10 ) ÷ - 1 ← evaluate parenthesis
= - 1 - (4) ÷ - 1
= - 1 - 4 ÷ - 1 ← evaluate division
= - 1 + 4
= 3

Pasos para resolver una ecuación linea
A=J(1+rt)
Usa la propiedad distributiva para multiplicar J por 1+rt.
A=J+Jrt
Intercambie los lados para que todos los términos de las variables estén en el lado izquierdo.
J+Jrt=A
Combina todos los términos que contienen J.
(1+rt)J=A
La ecuación está en formato estándar.
(rt+1)J=A
Divide los dos lados por 1+rt.
rt+1(rt+1)J=rt+1A
Al dividir por 1+rt, se deshace la multiplicación por 1+rt.
J=rt+1A
Work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number.
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
