Answer:
4. 54- 8.5x>20
Step-by-step explanation:
Catherine only has $54, so she cannot spend more than that.
The canvas will cost at least $20, but we don't know how much exactly.
The tubes cost $8.50 each.
So, she starts with a total budget of $54, out of which she will buy paints (8.5x) and she wants to have at least $20 left for canvas.
So, we transpose those facts into the inequity:
54 - 8.5x > 20
2 2/3 ÷ 2/4= 1/3
The answer is 1/3.
Answer:
quotient =6.2222222222
remainder =20
Step-by-step explanation:
Solution:
The given inequality is
−4 ≤ 5 − x ≤ 5
Breaking the inequality into two parts and then Combining Constants with constants in the inequality
⇒ -4 ≤ 5 -x ∧ 5-x ≤5
⇒ -4 -5 ≤ -x ∧ -x ≤ 5-5
⇒ -9 ≤ -x ∧ -x ≤ 0 --------(1)
⇒ Keep in mind , if , -a ≤ -b
then , if negative sign is removed , the inequality changes to
→ a ≥ b
Expression (1) Becomes
→ x ≤ 9 ∧ → x ≥ 0
The solution set of given inequality −4 ≤ 5 − x ≤ 5 is [ 0 , 9]
