Answer:
ELLA
Step-by-step explanation:
Given that :
Distance covered by Ella = 5/10
Distance covered by Sam = 7/8
Comparing each distance to 1/2
Ella = 5/ 10 = 1/2 ; 1/2 = 1/2 = 0.5
Sam = 7/8 = 0.875 ; comparing with 1/2
0.875 > 0.5
Given
Sam ran farther Than ELLA
Because 0.875 > 1/2
0.875 - 0. 5 = 0.375
Answer:
6 hours
Step-by-step explanation:
To start this, you must use an equation that models the amount that Mathew and Melanie made based on time. The total amount of money earned by the two of them is 120, and they both work for 8 dollars and hour, and Mathew worked 3 more hours, our equation is 120 = 8x +8(x+3)
We must first solve for x
120 = 8x + 8x +24
-24 -24
96 = 16x
x = 6
x is the amount of hours Melane worked.
Divide by 3 on both sides:
Square root both sides:
Take away 3 from both sides:
Divide by 2 on both sides:
Answer:
6423 to the nearest hundred=6400
