1.
which of the following systems is equivalent to the given system?
2/3 x - y = 2
x + 1/2 y = -3
2x - 3y = 6 and 2x + y = 6
6x - 3y = 6 and 2x + y = 10
2x - 3y = 6 and 2x + y = -6
2.
given the system of equations, what is the solution?
x + 3y = 5
x - 3y = -1
{(-4, -3)}
{(2, 1)}
{(-2, 3)}

step-by-step explanation:

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second

step-by-step explanation:

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).
