simplify the expression:
(-0.25x - 3) - (1.5x + 1.4)
THANK YOU!
(-0.25x - 3) - (1.5x + 1.4)
-0.25x - 3 - 1.5x - 1.4
-1.75x - 4.4
(3x+1.5)+(7x-4.5)
10x-4
(0.25x-3)-(1.5x+1.4)
Instead of using the distributive property to expand 0.25 x ( 16.60a + 12.20y), could you have first found the sum 16.60a +12.20y? Explain.
To simplify the expression (-0.25x - 3) - (1.5x + 1.4), you need to follow these steps:
Step 1: Distribute the negative sign across the second parentheses:
(-0.25x - 3) - 1.5x - 1.4
Step 2: Combine like terms:
-0.25x - 3 - 1.5x - 1.4
Step 3: Combine the x-terms (-0.25x and -1.5x):
(-0.25x - 1.5x) - 3 - 1.4
Step 4: Combine the constant terms (-3 and -1.4):
-1.75x - 4.4
Therefore, (-0.25x - 3) - (1.5x + 1.4) simplifies to -1.75x - 4.4.
