Answer:
<u>u ≤ -6</u>
Step-by-step explanation:
Given :
Add 2 on both sides :
- 22 + 2 ≤ -4u - 2 + 2
- -4u ≥ 24
Divide both sides by -4 (remember the sign changes direction when divided by a negative number) :
- -4u/-4 ≥ 24/-4
- <u>u ≤ -6</u>
Charge for x cars is 25x
Charge for y trucks is 50y
Total charge is 25x + 50y
25x + 50y = 3000
x + 2y = I20
Answer: x + 2y = 120
Answer:
D
Step-by-step explanation:
3.19 become 3.20 . 1.69 becomes 1.70. Then 3.20 plus 1.70 is 4.90 or 4.9.
