Social Studies rate, S = 30/ 1.5 = 20pages/hr
Novel rate, N = 150/2 = 75pages/hr
Novel rate as a % of Social Studies rate...
N/S × 100% = 75/20 × 100% = 375%
Answer:
1. -40=12x+8 : x=-4
2. -4x+2≥-6x : x≥−1
3. -11≤7x+3 : x≥−2
Step-by-step explanation:
1. Step 1: Flip the equation.
12x+8=−40
Step 2: Subtract 8 from both sides.
12x+8−8=−40−8
12x=−48
Step 3: Divide both sides by 12.
12x
12=−48

x=−4
3. Step 1: Flip the equation.
7x+3≥−11
Step 2: Subtract 3 from both sides.
7x+3−3≥−11−3
7x≥−14
Step 3: Divide both sides by 7.
