Answer:Robert's minimum age is 11 years.
Step-by-step explanation:
Let x represent George's age.
Let y represent Edward's age.
Let z represent Robert's age.
George is twice as old as Edward. It means that
x = 2y
Edward's age exceeds Robert's age by 4 years. It means that
z = y - 4
If the sum of the three ages is at least 56 years, it means that
x + y + z ≥ 56 - - - - - - - - - - 1
Substituting x = 2y and z = y - 4 into equation 1, it becomes
2y + y + y - 4 ≥ 56
4y - 4 ≥ 56
4y ≥ 56 + 4
y ≥ 60/4
y ≥ 15
z = y - 4 = 15 - 4
z ≥ 11

Answer:
6/5 or 1 1/5
6/5 is an improper fraction, so I didnt know if youd need an improper one or a proper one. They both are the same thing though :)
Step-by-step explanation:
4/10*3
They both need to be a fraction, and any number over 1 = that number. So,
4/10*3/1
4*3=12
10*1=10
12/10
Then, you have to simplify the fraction.
6/5 (bc 2 goes into 12 6 times and 2 goes into 10 5 times)
or 1 2/10= 1 1/5
Hope this helps. Plz give brainliest. Also, plz sub to Kgirl633 on yt.
We presume the temperature is decreasing at midnight, so reaches a low at 6 a.m.. The amplitude of the variation is (87-63)/2 = 12 degrees. We want the period to be 24 hours, so the argument of the sine function will be 2π(t/24) = πt/12. Then we can write
... d = 75-12sin(π·t/12)
