Answer:
2 integers/???
Step-by-step explanation:
Answer:
1) Solutions are x = 3 and x = 5/3
2) Solution are x ≤ 13/2 and x ≤ -3/2
Step-by-step explanation:
1) Given absolute inequality,
|3x-7| = 2
⇒ 3x - 7 = ± 2
⇒ 3x = 7 ± 2
![\implies x=\frac{7\pm 2}{3}](https://tex.z-dn.net/?f=%5Cimplies%20x%3D%5Cfrac%7B7%5Cpm%202%7D%7B3%7D)
![x=\frac{7+2}{3}\text{ or }x=\frac{7-2}{3}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B7%2B2%7D%7B3%7D%5Ctext%7B%20or%20%7Dx%3D%5Cfrac%7B7-2%7D%7B3%7D)
![\implies x = 3\text{ or }x=\frac{5}{3}](https://tex.z-dn.net/?f=%5Cimplies%20x%20%3D%203%5Ctext%7B%20or%20%7Dx%3D%5Cfrac%7B5%7D%7B3%7D)
2) l 2x-5 l ≤ 8
⇒ 2x-5 ≤ ±8
⇒ 2x ≤ 5 ± 8
![\implies x\leq \frac{5\pm 8}{2}](https://tex.z-dn.net/?f=%5Cimplies%20x%5Cleq%20%5Cfrac%7B5%5Cpm%208%7D%7B2%7D)
![x\leq \frac{5+8}{2}\text{ or }x\leq \frac{5-8}{2}](https://tex.z-dn.net/?f=x%5Cleq%20%5Cfrac%7B5%2B8%7D%7B2%7D%5Ctext%7B%20or%20%7Dx%5Cleq%20%5Cfrac%7B5-8%7D%7B2%7D)
![\implies x \leq \frac{13}{2}\text{ or }x\leq-\frac{3}{2}](https://tex.z-dn.net/?f=%5Cimplies%20x%20%5Cleq%20%5Cfrac%7B13%7D%7B2%7D%5Ctext%7B%20or%20%7Dx%5Cleq-%5Cfrac%7B3%7D%7B2%7D)
Answer: C. 5(6) + 0.65y
Step-by-step explanation:
Process of elimination.
65% of y = 0.65y
A has 65y, completely incorrect.
B has 6y, also completely incorrect.
<u>C has 0.65y, correct.</u>
D has 1.65y, also completely incorrect.
Answer:
1,75 kg
Explanation:
1 kg = 1000 g
2.5 kg = 2.5 × 1000 g = 2500 g
2500 g - 750 g = 1750 g
1750 g = 1750 ÷ 1000 kg = 1.75 kg
