1 answer:

4 0

Y = -4x + 5
y = 3x - 2

-4x + 5 = 3x - 2
+ 4x    + 4x
   5 = 7x - 2
      + 2 + 2
   7 = 7x
   7    7
   1 = x
   y = -4x + 5
   y = -4(1) + 5
   y = -4 + 5
   y = 1
   (x, y) = (1, 1)

Use the associative property of addition to find total of 1,10,18 in two different ways

Nuetrik [128]

Answer:

Step-by-step explanation:

According to the associative property of addition, for any given real numbers, a,b, and c;

$a+(b+c)=(a+b)+c$

$1+10+18=(1+10)+18$

$1+10+18=11+18$

$1+10+18=29$

Or;

$1+10+18=1+(10+18)$

$1+10+18=1+28$

$1+10+18=29$
