3(3x + 7) > 4-8(4 + 5x).
Answer:
x > -1
Step-by-step explanation:
Step 1: Distribute
3(3x + 7) > 4 - 8(4 + 5x)
(3 * 3x) + (3 * 7) > 4 + (-8 * 4) + (-8 * 5x)
9x + 21 > 4 - 32 - 40x
Step 2: Combine like terms
9x + 21 > 4 - 32 - 40x
9x + 21 > -28 - 40x
Step 3: Add 40x to both sides
9x + 21 + 40x > -28 - 40x + 40x
49x + 21 > -28
Step 4: Subtract 21 from both sides
49x + 21 - 21 > -28 - 21
49x > -49
Step 5: Divide both sides by 49
49x / 49 > -49 / 49
x > -1
Answer: x > -1

Step-by-step explanation:
B; 25.65+13.23+6.35=45.23
To do this mentally just add the 2 decimals places together first (1.23). Then just add the whole numbers (44). Then add the 2 numbers together, 44+1.23=45.23
y = -6x+32
