Let e = Emil's age and r = Rosa's age.
e + r = 27 since Emil's and Rosa's ages added together make a sum of 27 years.
(e - 9) = 2r - 9 since Emil's age minus 9 (9 years ago) is two times what Rosa's age is minus 9 (9 years ago)
Since you can't be twice someone's age for only 1 year, Emil is still twice Rosa's age.
So e + r = 27 and e = 2r.
Even though we don't know what 2r is, if we plug it in for e, we can find out.
2r + r = 27
This means 2r + 1r = 27.
Now you can simplify this to find each person's age.
3r = 27
27 / 3 = 9
r = 9
2r = 18
e = 2r = 18
e = 18
r = 9
So Emil is 18 years old and Rosa is 9 years old.
Answer:
64 + x + 85 + x + 55° = 180°
2x + 204 = 180°
The statement is " It was said that the circumstance was represented by the fact that the supper meal has 1500 calories."
<h3>Which statements describe the situation? </h3>
Generally, the equation for Calories consumed is mathematically given as
x = 2/3 of daily calorie
The calories consumed during breakfast and lunch
Cbl=1 - 2/3
Cbl = 1/3
Hence, calories consumed per day
1/3 * cc = 750
cc/3 = 750
cc = 750 * 2
cc= 2250 calories
Calories consumed at dinner
cd= (2250 - (750))
cd= 1500 calories
In conclusion, It was said that the circumstance was represented by the fact that the supper meal has 1500 calories.
