Answer:
no
Step-by-step explanation:
30 cents < 10 cents/dime × d dimes < 1 dollar × 100 cents/dollar
if d = 10
30 cents < 10 cents/dime × 10 dime < 1 dollar × 100 cents/dollar
30 cents < 10 cents/dime × 10 dime < 1 dollar × 100 cents/dollar
notice how the units bolded all cancel out, just leaving cents
30 cents < 100 cents is NOT < 100 cents
You need to isolate the "x" in both inequalities
5x + 7 ≤ -3 Subtract 7 on both sides
5x ≤ -10 Divide 5 on both sides
x ≤ -2
3x - 4 ≥ 11 Add 4 on both sides
3x ≥ 15 Divide 3 on both sides
x ≥ 5
This is your simplified inequalities:
5x + 7 ≤ -3 or 3x - 4 ≥ 11 ---------> x ≤ -2 or x ≥ 5 Your answer is A
X would equal 0 because u would use the distribution 3x+3=3x+3 and then subtract three from the three on the other side and then subtract 3x from 3x and then 0
