The property used is the Associative property
3 × 70 = 3(70) = 3 (7×10) = (3×7) ×10
The formula is
a × bc = a (bc) = a (b×c) = (a×b) ×c
3x - (2x + 8) = -6
3x -2x - 8 = -6
x - 8 = -6
x - 8 + 8 = -6 + 8
x = 2
Answer:
x = -4 y =-4
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
The inequality is: x < 90 ( or x is less than 90 ).
Answers A and D are represented by: x > 90.
Answer B is represented by: x = 90.
Therefore this situation is:
C ) A kiddie pool holds under 90 L of water.
