Answer:
Elgas is 35.
Step-by-step explanation:
Let's set up an equation.
Alvin is 7 years younger than Elgas.
A = E - 7
The sum of their ages is 63.
A + E = 63
Let's use substitution.
Plug in the first equation of A into the second equation.
A + E = 63
(E - 7) + E = 63
Combine like terms.
2E - 7 = 63
Add 7 to both sides.
2E = 70
Divide both sides by 2.
E = 35
Elgas is 35.

To divide a number by a fraction, multiply this number by the reciprocal of the fraction.

Answer:
$32.80
Step-by-step explanation:
For this case we have that the total daily protein consumption is given by:
Now, we find the percentage corresponding to breakfast:
53g ---------> 100%
17g -----------> x
Where "x" represents the percentage of protein equivalent to breakfast:
Thus, at breakfast approximately 32.08% of the total protein should be consumed.
Sasha worked for 75 dollars an hour. it costs her 20 dollars for gas to get to work. how many hours does Sasha work?
The answer is 923.2 because I found the circumference of the circle which was 153.86 and since it is the volume of the cone you would use the formula V=1\3BH. Using that formula you would do: 1/3*153.86(18) and that would get you 923.16 and since it looks like the answer wants you to round, you would get 923.2. Hope that helps!
