Answer:
42kg of water
Step-by-step explanation:
84kg person contains 56kg of water
63kg person contains (x)kg of water
(x)kg of water = (63x56)/84=42kg of water
A: no
X = 3
2x + 3
2(3) + 3
6 + 3
9
For the other one:
2(x + 3)
2(3+3)
2(6)
12
2x + 3 and 2(x + 3) are not equivalent because one has parentheses, which means you will have to do parentheses first instead of multiplication (PEMDAS rule)
Hope this helps!
Answer:
about 4.52
Step-by-step explanation:
Since pi times radius squared is the formula for area, you would first divide 64 by 3.14 to get about 20.4. Then since you square the radius, you would do the opposite and find the square root which is about 4.52.
129.95 * 0.55 = 71.4725
71.4725 * .06 = 4.28835
71.4725 + 4.28835 = $75.76
Answer = $75.76
