Answer:
24 students
Step-by-step explanation:
So we started with 32 cups of juice.
Kahled drunk 2 cups so (32-2)=30 cups is left.
If x represents the number of students he receive juice and each student gets the same amount of juice which is 1.25 cups, then we have the equation
1.25x=30 to solve for x.
Divide both sides by 1.25:
x=30/1.25
x=24
24 students receive juice
Answer:
25
Step-by-step explanation:
Use the order of operations.
Answer: a=2 b= 11/6 or 1 5/6
Step-by-step explanation:
Let the distance of Judy from intersection is x and distance of Jackie from intersection is y.
We convert the given information to equations, step by step.
Point 1: When Jackie is 1 mile farther from the intersection than Judy.
This means y is 1 mile more than x.
So,
y = 1 + x
Point 2: The distance between them is 2 miles more than Judy’s distance from the intersection.
Distance between is x+ y.
So, x+y is 2 miles more than y.
x+y = y + 2
⇒
x = 2
From point 1 we have:
y = 1 + x = 1+ 2 = 3
So,
Distance of Judy from intersection is 2 miles and distance of Jackie from intersection is 3 miles.
Let Mary's age be x.
Paul is three times as old as Mary, so Paul's age would be 3x.
Peter is four times as old as Mary, so Peter's age would be 4x.
The sum of their ages is 64
⇒ Paul's age+ Peter's age+ Mary's age= 64
⇒ 3x+ 4x+ x= 64
⇒ 8x= 64
⇒ x= 64/8
⇒ x= 8
Paul's age is: 3x= 3*8= 24
Peter's age is: 4x= 4*8= 32
Final answer: Paul is 24 years old.
Peter is 32 years old.
Mary is 8 years old.
Hope this helps~
