Answer:
<u>A</u>
Step-by-step explanation:
<u>Given</u>
<u>Solving</u>
- Take the square root on both sides
- √x² = √9/4
- ⇒ x = 3/2
- <u>Option A is the correct option.</u>
4/5 x 2/8 = 0.2 or 8/40 = 4/20 = 2/10 = 1/5
The answer for B is 270.
450 • 0.6 =270
Answer:
x = 129, rounded
Step-by-step explanation:
3x + 144 = 532
<u> -144 -144 </u>
3x = 388
divide both sides by 3
x = 129, rounded
