3P= 1/2 is an equation to represent the problem
Answer:
75
Step-by-step explanation:
Answer:
1/4 25%
Step-by-step explanation:
The spinner has 4 sides so the denomination is 4 and you are trying to get one of the 4 sides each so it would be a 1/4 chance for both answers so 25%
1.) Let their speed be x, then distance travelled = speed x time
1.5x + 2.5x = 240
4x = 240
x = 240/4 = 60
Their speed is 60 miles per hour.
2.) Let catie's brother's age be x, then catie's age is 3 + x
x + 3 + x ≤ 31
Required inequality is 2x + 3 ≤ 31
2x ≤ 31 - 3
2x ≤ 28
x ≤ 28/2
x ≤ 14
Therefore, the oldest age Catie's brother can be is 14 years old.
3.) Let June's age be x, then her father's age is 6x
6x + x ≥ 77
7x ≥ 77
x ≥ 77/7
x ≥ 11
The youngest age Julio can be is 11 years old.
20,000,000 + 400,000 + 80,000 + 4,000 + 100 + 60 + 3
