Answer:
She drove 3 hours
Step-by-step explanation:
Leslie drove 2/3 of the 4 1/2 hours trip. To determine how long she drove, multiply these numbers together.
2/3 * 4 1/2
We need to change the second number to an improper fraction
4 1/2 = (2*4 +1)/2 = 9/2
2/3 * 9/2 = 9/3 = 3
She drove 3 hours

The algebraic representation of the expression ten minus one-third of number is 4 is 10 - 1/3x = 4
<h3>Algebra</h3>
ten minus one-third of number is 4
let
10 - 1/3x = 4
10 - 4 = 1/3x
6 = 1/3x
x = 6 ÷ 1/3
x = 6 × 3/1
x = 18
Therefore, the algebraic representation of the expression ten minus one-third of number is 4 is 10 - 1/3x = 4

#SPJ1
Answer:
Julia found 5 coins
Step-by-step explanation:
lets take the # of coins julia found as "x"
alice found6
davi found 5
lucas found 6
and carter found 8
remember how to calculate mean( add all numbers and divide by the# of numbers)
so
6+5+6+8+x/5=6 (since there are "5" terms)
so
25+x/5=6
treat this like a linear equation so multiply by 5 on both sides
25+x/5(5)=6(5)
25+x=30
subtract "25 on both sides"
25-25+x=30-25
x=5
hope this helps
